DSE vs. SpeedTech Performance. . .

Fitting a 315 on that frame is pretty awesome

But the trade-off is less header clearance due to the frame rails being located further inboard to allow room for that 315.

I'm sure the frame on the Speedtech is alittle narrower, but the bigger issue is just the header and steering shaft. The Camaro we are doing is tight on the headers with the stock position steering shaft. The frame is just narrower in that area over the DSE sub. With the UCA position of the Speedtech makes it a battle. But that geometry position is the gain in clean slate design.

Granted we have Porto type LT4 headers but it's not much different over the LS headers. Plus the steering column has the electric power assist so that add a few variables.

But doesn't change much at all.

YES the steering and headers are TIGHT. but they do work, we have a couple in the shop right now having everything installed including RedZed, Rogers 69. and it is all working out as planned. the port location on the LT is slightly different from what I have seen also.

We can supply all the parts column, shaft kit, headers that all work together.

Blake can you post up a couple of pics of the steering shaft to header clearance on the extreme subframe?

Blake - I hear you have the 1st get headers done. When can you post up some pics of the 2nd Gen headers fitted up. I spoke to you near X-mas and you seemed to be close to having them ready. Any update? I'm interested to see the overall fitment but mostly the ground clearance since that's a huge issue for 2nd Gen cars.

GROUND CLEARANCE!! Exactly. we decided to do a 3/4 length header for that very reason. in testing Ultimate tells me they are only 10hp down on some of there 3/4 length VS full length. I figured that was acceptable as full length headers that are SMASHED not only look and sound bad but are probably worse the 10hp Plus the customer isn't happy.

I HATE headers that hang down this way you will be able to run a 3" tube as close to the floor as possible the Trans cross member will be the deciding factor but at that point oval tubing would be the answer.

Tomorrow!! Rogers is all mocked up and just about finished.

After measuring & running calcs on all of them, I'm clear they each have good bump steer & camber gain.

The notable differences (advantages) of the Speedtech eXtreme clips & frames are:
* 100% Ackerman for increased grip on inside front tire.
* A spindle custom designed for this suspension ... not the other way around.
* Roll Center above ground in dynamic conditions ... and in exact optimum location ... for increased front end grip ... and corner entry stability.
* Fits 315 front tires with clearance for 30° of steering.
* Increased caster capacity for optimum tire contact patches on both front tires. (Slugged for 7° to 9° static caster ... plus 0.6°-2.0° caster gain iin dive).
* A real racing power steering rack from Sweet ($900) ... with dual power to live forever & excel at turning sticky 315's ... instead of reproduction/remanufactured production car rack from Mavel ($300).
* 3-piece race style front sway bar with Speedway Engineering chromoly bars offering a range of rates from 400# to 1300#.
* Lastly is the option to come with Ridetech or JRI shocks with digressive pistons & my modern secret sauce, high grip valving.

Proof is on the pavement, not a sheet of paper. I'm Really excited to see a comparable year/model cars compete to show which handles better. I wouldn't be so quick to say anything negative about C5/C6 spindles or OEM steering racks. If it works, it works. Modern cars especially vettss are kicking butt out there at the autocross

Ideally a sheet of paper is where it all starts.

true but just bolting on a system designed well for another chassis and platform does not usually translate very well to all or other platforms. Same goes for racks, just because the "fit" doesn't make them optimum.
