The Subframe Market Grows and Specializes
Part 1
Hello: This may or may not be interesting for most, however I did a small amount of research into what Sub frames makers are out there and what is the current market offering by them. I will warn you, this is a very long post, so if it's just going to bore you or P*ss you off, feel free to pass on it. I wasn't able to get EVERY product of it's kind on the market, but just a sampling. If you know some that could be added to this list, please add them to it. Some of the samples I took I didn't include all the links associated with it, so please if your interested an all the information, click on any links you can find with regards to the sub frame. As mentioned in another post some companies are really broadening their product line to hit all the sub frame niches that might be in the market. One company offered 4 different. (Drag, Road Race, Wide Track, and replacement) Others are changing the track width from -2 inches to +4 inches. Here is what I have found so far. Please add to it.

The system features Chassisworks g-Machine double A-arm, rack-and-pinion crossmember. Its direct bolt-on design enables a time-saving, straight-forward installation that requires absolutely no custom fabrication. Unlike others, ours is the only subframe that includes mounting provisions for all major vehicle system components, as well as an optional chassis stiffening, subframe connector system. As an option, factory welded motor plate and mid plate brackets can be added for vehicles requiring maximum chassis stiffness. Base bolt-on subframe (770, above) must be combined with a suspension and steering package (PKG A-ARM, right) to form a complete system. Precision Fit Quality Through Advanced Technology One of the key pieces of advanced technical equipment used in development of our vehicle retrofit component system is the FaroArm portable coordinate measuring machine. The FaroArm is an articulating, multi-segmented arm that enables precise three-dimensional digitization of vehicle surfaces and mounting points, accurate to within .003”. To begin, multiple identical vehicles are extensively measured to find the OEM tolerance range we must accommodate in our final design. From these scans, an exact model of the vehicle chassis is created in our Pro/Engineer software. Engineers can then accurately and efficiently design systems, simulate movement or conditions, and conduct Finite Element Analysis (FEA) testing to optimize performance and durability before physically making any parts. Manufacturing fixtures and tooling are also based on the original vehicle scans, avoiding loose tolerances of transferred prototype dimensions, and ensuring the quality and ease of fit of the final product. Clean Sheet Design, Not Revised OEM Geometry Chassisworks’ g-Machine front end is a truly versatile “high- performance” system, suitable for g-Machines, muscle cars, or any project in need of optimized handling. State-of-the-art en- gineering workstations with Pro/ENGINEER software, combined with our advanced, automated factory enabled Chassisworks’ engineers to create a current technology, competitively priced g-Machine front clip and suspension for 1967-69 Camaros and 1968-74 Novas. The complete suspension and steering system is factory welded directly to the bent-tube billet-com- ponent crossmember, ensuring perfect geometry, and elimi- nating the need to weld multiple pieces, or make complicated measurements while installing the system. Chassisworks new g-Machine design is far superior in performance, reliability, and ease of installation than components made to replace 40-year-old 60’s muscle car geometry, and variants of the 30-year-old Mustang II suspension. Although late-model Corvette based systems offer similar performance, your choice of wheels is extremely limited to flat-face, high-negative-offset wheels. End of Part 2 |

The Truth about Hydroforming and It’s Myth of Superiority
With the tremendous hype surrounding hydroforming we feel its time to explain the pros and cons of Hydroforming. Hydroforming starts with a pre-bent tube in the basic frame shape needed. Internal hydraulic pressure is then applied to further form the bent tube into the shape of a mold cavity that matches the exterior of the new frame component. Hydroformed components can be produced very inexpensively which explains their popularity with OEM automobile manufacturers. The major drawback to hydroforming is that the tooling is very expensive. As the demand for frames in the automotive after market is very small compared to the volume an OEM builder needs, the tooling cost must be amor- tized over an infinately smaller quantity of parts. This alone could add hundreds of dollars to the selling price of a frame. The second problem is the tube must be stretched to flow into the mold cavity thus decreasing its wall thickness. This also makes some shapes impossible to form. This is why Hydroformed frames look so much like a stock frame, they both suffer from the same manufacturing limitations. Chassis works’ manufacturing method to produce complex aftermarket frames avoids the drawbacks of hydro forming. Laser-cut sheet blanks are formed into shape with a sophisticate CNC controlled forming The FaroArm is used to digitally scan multiple vehicles and create an exact computer model for development. 3 press and then robotically welded together. This process produces very elaborate and vehicle specific frames which can be built economically in the small aftermarket quantities Chassis works can accomplish this because we have the most advanced state-of-the-art manufacturing facility building aftermarket frames and components. Our flexible manufacturing methods were designed specifically to build lower volume sophisticated parts. Look at our chassis products and you will see that they are all very elaborate, application specific, with a tremendous amount of individual accessories to compliment each other. The Chassisworks’ design is superior in these key areas: Chassisworks fabricated subframe is larger and stronger than all other tubular designs. Large 3” x 4” subframe structure at the critical chassis stiffness area from the suspension cross- member rearward, through the firewall mounts. By making our own billet rack-and-pinion assembly, we are able to offer perfect front-suspension geometry at the correct hub-to-hub width. Rack and pinion is placed forward of the axle centerline (front steer) for better oil-pan clearance and rotates to eliminate sharp universal joint angles and improve exhaust clearance. Virtually no bumpsteer in 6” of suspension travel enables predictable handling regardless of the vehicle’s changing pitch-or roll-state. Broad lower A-arm increases load capacity and stability during braking and cornering. Lower A-arm length reduces track width change and roll center movement during suspension travel, for smoother transitions entering and exiting turns. Lower shock mount is located very close to the balljoint, increasing the shock-motion ratio, and allowing use of lighter, lower rate springs for better suspension control without degrading ride quality. The g-Machine spindle is taller than OEM spindles which increases camber gain during body roll, keeping tires in better contact with road surface. Two-inch dropped spindle lowers ride height and center of gravity to improve overall handling. Short/Long Arm Suspension (SLA) layout is a compact, low-profile suspension design that leaves plenty of room around the engine. Traditional hub-style spindle accepts up to 4” brakes with more wheel choices than Corvette-style spindles. Suspension and Steering Components A broad range of suspension and steering components enable the system to be custom outfitted to match your performance requirements. Options include: manual or power rack-and-pinion, Street- or g-Machine control arms, behind-crossmember or forward-of-rack mounted antiroll bars, fabricated or sculpted spindles, and -3/4”-rotor for street brakes, or 3”- and 4”-rotor for high-performance brakes. Bolt-on installation, perfect geometry, and tailored performance make the g-Machine system an excellent choice for your next project. 4 True Direct-Fit NoFab Installation Direct-fit installation ensures that all major drivetrain components remain in their exact factory positions. Engine height and set-back are stock, requiring no additional hood clearance or modification to the firewall or transmission tunnel. Two mounting styles of antiroll bars are available. The standard rear mount antiroll bar has the same forward clearance as the stock Camaro clip. Optional splined-end, forward-mount, antiroll bar attaches under the front frame rails, forward of the rack and pinion to provide approximately two-more inches of forward pan clearance. A hub-to-hub width of 60” matches the original factory dimensions, allowing use of preexisting or factory wheels without the need for spacers. Ride height is approximately -/” to ” below stock and maintains 4-/” of ground clearance below the suspension crossmember. The system accepts factory height (5.5”) tires, with up to an ” tire section width and 5” wheel backspacing. Acceptable sizes include: 75/45-6, 75/40-7, 75/35-8, 75/30-9, and 75/5-0. Note: 967-68 Camaro fenders may limit tire section width to 9.5”. \ Fabricated Subframe with Integrated g-Machine Crossmember Subframe Design and Construction The subframe structure is made up of specially-fabricated frame rails, frame horns, and our g-Machine suspension crossmember. Our unique completely enclosed subframe structure is stronger and more rigid than commonly used open-channel designs. Each frame rail is assembled from four separate, -gauge (.04”) sheet metal panels to create a strong, yet lightweight boxed structure. This assembly procedure enables us to construct a tapering frame rail with uniformed wall thickness throughout the entire structure; not possible by any other manufacturing technique. Rail width remains constant at 3”, but height gradually increases from 3”-tall, underneath the body where clearance is of concern, to 4” at the suspension crossmember, where strength and stability are highly important. Rail panels are CNC-laser cut and include numerous detailed positioning features. Once the contour bends have been made at our fully-automated press, the panels are assembled using the positioning features. Similar to a three-dimensional puzzle, the rail panels can only be fit together in the absolute correct shape. The four corner seams are welded with a continuous bead to completely bond the joint. Subframe rails, suspension crossmember, and various mounts are then assembled and welded in a fixture. The final fixture welding of the sub-assemblies ensures that body, motor, transmission, and bumper mounts are perfectly positioned for a trouble-free installation. Completed base subframe assemblies are shipped as bare steel with raw corner welds. As an option, welds can be sanded smooth ready for paint or powder coating.

Single-Piece 4” x 2” g-Machine Crossmember
Bent-tube, billet-component crossmembers are a completely closed rigid structure with greater strength, and resistance to bending and twisting than other designs. Formed from a single-piece of 4 x x .0” steel tubing, large radius mandrel bends are placed at each end to distribute loads throughout the crossmember, eliminating fatigue points at critical areas. Slots for the billet-mount tabs are machined in a large horizontal machin- ing center with dedicated fixturing to guarantee correct component geometry, ensuring the suspension moves as designed. Interlocking Slot-Tab Technology Self-fixturing female slots used with machined male tabs, provide an interlocking assembly method which enables A-arm, rack and pinion, and shock mounts to be accurately positioned in all axes. This guarantees the suspension will perform as designed. Non-interlocking designs are not nearly as accurate after welding. Superior spray- arc welding process produces the best weld penetration with excellent appearance. Billet Steel A-arm Mounts with Pivot Pins Billet-steel, CNC-machining allows us to create A-arm mounts with specific areas of increased thickness for added strength; not possible with other designs. Unlike slot or eccentric mounted A-arms, Chassisworks exclusive fixed-axis pivot-pin design eliminates the possibility of shifting pivot shafts, provides greater shear strength and increases bending resistance. Threaded bosses at each end of the mount enable use of set screws to lock A-arm pivot-pins into position. Using slot-tab technology, upper A-arm billet-mounts snap and weld into place providing anti-dive geometry and cap- ping the open ends of the 4 x ” crossmember to better distribute forces, decrease flex throughout the structure, and provide a solid location for the upper shock mount. The lower A-arm mount is a single-piece component passing directly through the crossmem- ber and supported by the antiroll bar mounting plate to distribute bending forces throughout the crossmember. This increases rigid- ity and geometry accuracy of the control arm for more predictable handling. One-Piece Clevis Shock Mount Our g-Machine upper shock mounthas a -5/6”-wide, formed clevis which accepts /” mounting hardware and provides adequate clearance for use with VariShock coil-overs or Shock- WaveTM air suspension. Our one-piece design with integrated gusset across the top, and sides extending downward, bridge the billet upper A-arm mount to the 4 x ” crossmember. This provides a larger, more stable mount base, with better appearance than welded designs, and eliminates bending fatigue possible with common sheet metal or tubing mounted designs of other manufacturers. Anit-Roll Bar Mount PlateSingle-Piece Billet Lower A-Arm Mount Billet Upper A-Arm Mount Locating features are machined into each crossmember to enable self-positioning of billet components. Billet rack-and-pinion mount inserts into machined slot on crossmember. 6 Billet Rack Mounts and Clamps Steel billet rack mounts, using dual slot-tab technology, form an interlocking bridge between the x 4 cross member and billet aluminum rack brackets. The angled mount fixture welds to 4 x ” cross member, attaching to rack body at widest points, while positioning rack above bottom of cross member, safe from road hazards. Billet aluminum rack clamps attach into interlocking grooves in the rack gearbox, preventing flex in hard cornering unlike rubber-mounted designs. This also allows rotation of input shaft to aid steering shaft installation around engine obstacles and exhaust system. Subframe Installation Features Detailed Installation Guide Included with each g-Machine Camaro subframe is a very detailed 04-page installation guide. The guide features over 300 individual photos completely illustrating the installation process at each and every step. Beginning with clip assembly, and then continuing on with removal of factory components and final installation, our comprehensive guide makes installation and setup an uncomplicated task. Alignment Holes To simplify subframe alignment in relation to the body, the OEM alignment holes have been duplicated on the g-Machine sub frame. Note that not all replacement subframes on the market have this important feature. A pair of CNC-machined alignment pins is supplied to make subframe installation simple, and highly accurate. Body Bushings Body bushing kits are available for g-Machine or stock sub- framed 967-69 Camaro/Firebirds and 968-79 Novas; in urethane (P/N 68) or billet aluminum (P/N 686). Urethane bushings have adequate rigidity for performance street cars, but significantly dampen noise and vibration transferred into the passenger area. Billet aluminum bushings are more suitable for road race or drag race vehicles where maximum rigidity is required, and noise and vibration are less of a concern.

The bracket overlaps the entire top panel of the subframe, increasing total material thickness. Two sets of mounting holes at the bracket allow use of the same g-Machine tubular transmission crossmember with V8 engine blocks, or modern LS engines. Mounting hardware is inserted from the bottom side of the bracket and threaded directly into the weld nuts of the crossmember. This eliminates the need for hardware access space above the mounts and allows the crossmember to be positioned tighter against the body into the channel in the stock floor to obtain maximum exhaust clearance. Direct-fit transmission crossmembers are available for Turbo 350, Turbo 400, Powerglide, 700R4, 00-4R, 4L60, 4L65E, Muncie 4-speed, Richmond 5- or 6-speed, and many Tremec 5- or 6-speed transmissions. 6067 - 4-Speed, Powerglide, Turbo 350 6068 - 700R, Tremec, Richmond 5-speed, 460L 6069 - Turbo 400, 00-4R, 4L65E 6070 - Richmond 6-speed ROD Transmission Crossmembers Part Number Description Position1 Price 6067 4-Speed / Powerglide / Turbo 350 Transmission Crossmember 0.55” $65.00 6068 700R / Tremec / Richmond 5-Speed / 4L60 Transmission Crossmember .95” 76.00 6069 Turbo 400 / 00-4R / 4L65E Transmission Crossmember 6.848” 86.00 6070 Richmond 6-Speed ROD Transmission Crossmember 4.375” 07.00 Footnote: Position of mount is the measured distance from back surface of engine block to center of transmission mounting holes.

Bumper and Core-Support Mounts
All factory bumper and core-support mounts for both 967-69 Camaros and 968-7 Novas have been duplicated at the g-Machine frame horns. Weld nuts are factory installed in fixed positions or movable adjustment slots to simplify installation. Weld nuts eliminate the need for backside hardware access, allowing a boxed frame horn design that contributes to front-end vehicle stiffness. Inner Fender Splash Flaps Durable rubber splash flaps are available to take the place of the OEM pieces. Debris within the engine compartment is kept to a minimum due to the flaps contoured edge, specifically designed to fit the g-Machine suspension and OEM inner fender. Part Number Description Price 6656 Inner Fender Splash Flaps for OEM Inner Fender with g-Machine Front Suspension (pair) $93.00 Clutch Pivot-Shaft Bracket Mount Three threaded holes along the driver’s side frame rail are used to mount our clutch pivot shaft bracket (P/N 633), sold separately. The bracket supports the factory clutch pivot shaft in the same position as the factory bracket. Part Number Description Price 633 Clutch Linkage Frame Pivot Mount, for g-Machine Camaro Subframe (770) $30.00 Parking Brake Brackets Provisions to mount the factory parking brake cable are included as part of the welded subframe assembly. A sleeve allows the cable to be routed through the driver’s side frame rail, protecting it from possible undercarriage scrapes, and permitting use of the factory adjustment mechanism and passenger’s side cable anchor. Subframe Connector Mounts The g-Machine subframe is the only system available with a built-in subframe connector mount. Mounts are CNC-machined billet steel and serve to cap the rear end of the frame rail for added rigidity. Tubular sub frame connectors simply bolt to the mount extensions and to the factory leaf spring mounting bracket, tying front and rear chassis structures together. Bolt-In Subframe Connectors Chassis works is the only manufacturer to incorporate a bolt-on chassis stiffening system into our direct- fit 967-69 Camaro/Firebird, 968-7 Nova subframe design. Our unique clamping method is simple to install, and creates a connection equally strong as a welded connector. Once installed the connector system provides a direct structural bridge between the rear subframe at the spring mount, and the g-Machine front suspension subframe. A noticeable improvement in chassis rigidity yields more responsive handling and sharper acceleration, while relying less on the flexible sheet metal for chassis stiffness. The g-Machine sub frame’s profile-milled, billet-steel connector mount enables a non-flexible, precision fit for the subframe connector. The tubular connector fits snugly over the mount, flush along the lower face, and is securely held in place by doubling plates to more evenly distribute the clamping force from two /” grade 8 bolts, x Tubular Subframe Connector Black Powder- Coat Finish Grade 8 Mounting Hardware Doubling Plate Clamp Body Bushing Mount (hollow underneath) Slotted Holes for Easier Installation Billet-Steel Connector Mount Doubling Plate Clamp Nylon Insert Locknuts Parking Brake Mount with Frame Sleeve Chris Alston’s Chassisworks, Inc. 8661 Younger Creek Drive Sacramento, CA 95828 [email protected] www.cachassisworks.com Order: 800-722-2269 Tech: 916-388-0288 Fax: 916-388-0295 All prices subject to change.

Note: One pair CLICK HERE TO SEE PICTURES OF THE DEVELOPMENT PROCESS HYDROFORMED SUBFRAME Detroit Speed & Engineering’s all new front subframe is a bolt-in replacement for the original stock subframe. It improves the handling and ride quality by utilizing DSE’s unique suspension geometry. It is the ONLY subframe in the aftermarket industry with hydroformed frame rails. The hydroformed frame rails feature strength and stiffness, relatively low weight, and precise quality and repeatability. Hydroforming preserves the steel’s strength and stiffness because it is performed at low temperatures, unlike traditional high temperature processes which decrease material strength. The subframe comes complete with the following components: • Hydroformed Framerails • Stamped Crossmembers • Tubular Upper and Lower Control Arms • Coilover Shocks for Subframe with "Detroit Tuned" valving • Coilover Spring • Power Rack and Pinion Steering • Splined Sway Bar • C6 Steering Knuckles and Bearing Packs A 10" wide wheel can be packaged without modification to the inner wheel wells. Both the main and secondary crossmembers are stamped for structural rigidity. SBC, BBC, LS1, LS2, and LS7 engines have been designed as a direct bolt-in into this subframe. The DSE subframe has been designed, engineered, and developed for the road and track. This subframe blends the benefits of current OEM technology and aftermarket performance into one product! The subframe is available uncoated and unassembled for your SBC, BBC, or LSX engines. We also offer the subframe powdercoated satin black and assembled.

It also fits 1968-72 Chevy Novas. Through use of a specially modified C5 spindle with lowered steering arm mounting, the AGR power rack & pinion steering unit is mounted some 2” lower in the frame, which allows for a lower CG and improved handling. Big block, small block and LS-series Chevy engines can be employed, as well as virtually any popular automatic or manual transmission —including Richmond 5/6-speeds, Tremec T56 and TKO, Mncie, Powerglide, TH-350 & 400, 700-R4 and 4L60E— thanks to a series of available mounts. Designed through use of FEA (finite element analysis) the 105 lb. front clip has outstanding strength and stiffness, yet is significantly lighter than the bulky OEM unit. With a reduced unsprung weight, forged aluminum C5 Corvette control arms, a shortened front view swing arm, modified caster, and adjustable coil-over shocks, Morrison’s GT-Sport clip will provide awesome handling. It comes with a near-stock tread width for optimum wheel fitment opportunities, and can use a wider-than-stock tire (265/35R18 tested). As no cutting or welding is required, installing a GT-Sport clip can be performed by most competent do-it-yourselfers in the comfort of their own garage. With an aggressive, lower stance and incredible handling characteristics, the look and “feel” of a Morrison GT-Sport Clip-equipped Camaro is unbeatable! AME '07 Cat hel 1/16/07 4:39 PM Page 35 ============================================== End of Page 7 Thanks for your patience I hope this turns out to be helpful. (At least I tried) As time goes on the products offered to us are continuing to evolve for the better. Please help sum up the Important facts between these products. (Pro and Con and why?) I think it would give the consumer and the manufacturers a way of making a better purchase decision, and possibly an insight into future development direction. Add your thoughts and additional info you find. I think it would be really revealing how each stack up against each other. Thanks, Ty O'Neal |
nice break down, the compare feature on Amazon.com would be envious but you lost me about the end of page three. Those squares made me crave french toast so you might want to delete those. Maybe put a boobie picture somewhere in the middle to wake people up.
Can you embed a few pictures...no boobies as that was a joke. French and surup makes me babble and playfull. |
There's a lot of good information there, thanks for posting it, but I think if anyone were to actually figure out what it would cost for what they want they would come up with a very confused total.
I've had Chassisworks quote me a clip before and they went through all the options on the phone with me. I'm sure Art Morrison, DSE, etc. would too. |
Tyonel, good documentation!!!
