A little copy and paste action:
Do the AFX spindles change my track width?
No. The AFX spindles were engineered to retain the factory track width of a disc brake equipped spindle. Wheel back spacing changes should not be required.
What kind of brake system will fit the AFX spindles?
Any braking system designed to bolt onto a C5 or C6 Corvette will bolt directly onto the AFX spindle. We distribute for AP Racing, Baer, and Touring-Classics, but we also recommend Wilwood, SSBC, Brembo, Alcon and others.
How far will the AFX spindles drop my car?
Both the tall and the stock AFX spindles will lower the vehicle approximately one inch.
I have the Guldstrand Mod or DSE coil over system on my car. Which AFX spindles should I use?
We recommend the stock version of the AFX spindle for use on the F body in these instances. A tall spindle could be substituted in the event of a race only vehicle, as the camber gain is too aggressive for street driving.
I have the B body spindles on my car. Will the AFX spindles fit my current setup?
Yes. The AFX spindle was engineered to be a direct upgrade for the plagued B body spindle swap. The AFX spindle cures all of the negative issues associated with the B body spindle such as bump steer, and the decreased turning radius that occurs when installing the B body spindle. Just be sure to note you have a B body lower ball joint when ordering so we can outfit your spindles with the correct screw in ball joint inserts.
What is the bolt pattern for the AFX spindles?
The AFX spindles use a C5 Corvette sealed hub assembly with a 5 on 4.75” bolt pattern. Additional benefits of the sealed hub are larger bearing surfaces for open road racing, and integrated individual wheel speed sensors.
What kind of lug studs are offered on the AFX spindle?
The standard option is a metric stud 12mm x 1.5. We can outfit the hub with a race stud in either 14mm x 1.5 or in ½” x 20. Additional machining and cost is involved in the upgrade.
Do I need to run bumpsteer adjustable tie rod ends with the AFX spindle?
No. The AFX spindles were engineered with bump steer in mind. We designed the steering arm attachment points lower than factory to improve the bumpsteer for the F body cars. By re-using the factory F body steering arm, we were able to bring bump steer down to nearly zero. Because the A body cars are front steer (and therefore require the steering arm holes to be raised from the factory location) a new steering arm was designed in-house to cure the issue. Bump steer correcting tie rod ends can still be used as an additional tuning method, but the install should be measured afterwards with a bump steer gauge to make sure that the issue was improved, and not worsened.
What applications do the AFX spindles fit?
Currently the AFX spindles fit the 64-72 A body cars, the 67-69 F body cars, and the 68-74 X body cars. In development are fitments for the 78-88 G body, 70-81 F body, and 73-81 B body. Any street rod styled suspension that uses one of these vehicles as a donor for its spindle choice, can be replaced with an AFX spindle.
Will my aftermarket tubular control arms fit with the AFX spindle?
Yes. The F/X body version of the AFX spindle will fit with any factory or aftermarket replacement control arm. This includes Global West, DSE, Hotchkis, Speed Tech, and others. For the A body version of the tall AFX spindle, the upper control arm will have to be replaced. We recommend SC&C or B body spindle swap arms from Global West, Hotchkis, and other similar manufacturers. If using a stock version of the AFX spindle on the A body, both stock and aftermarket will bolt up, so long as they were not designed with the B body spindle swap in mind.
I have an aftermarket rack and pinion unit installed. Can I still use the AFX spindle with this steering setup?
Yes. The AFX spindle has a bolt on steering arm, which can be replaced with aftermarket arms designed for rack and pinion conversions. This includes the BRP, Flaming River, and UniSteer conversions.
How much weight does the AFX spindle shed over a stock type replacement?
The AFX spindle is forged from 6061 T6 aircraft spec aluminum, and is therefore exceptionally strong and light weight. The weight of a bare AFX spindle to bare factory spindle yields close to a 4 lb savings per side. Fully loaded spindles net a 1.5lb savings over factory per side.
I have a Baer racing track kit on my car now. Will it fit on the AFX spindles?
No. Most Baer Racing Track kits are based of off the C4 Corvette PBR brakes. The mounting bracket of the caliper will not match up with the forged bracket of the AFX spindle, plus the rotor offset is too great to work with the C5 Corvette brake design. We recommend selling of the Baer kit hanging on the factory spindle as a complete unit to help offset the cost of a new C5 Corvette braking system.
What kind of ball joint tapers do you offer on the AFX spindle?
The AFX spindle is offered with either a 1.5 taper per foot (roughly 7 degrees), or a 2.0 taper per foot (roughly 10 degrees). Custom tapers can be machined into the inserts for an additional cost.
What is the overall height of the Tall AFX spindle?
The tall version of the AFX spindle is 8.5” in over all height from lower ball mounting joint surface to top ball joint mounting surface.
What is the reason for the stock version of the AFX spindle?
We opted to re-create the AFX spindle in a stock height so that people with the Guldstrand Mod, DSE weld-in coil over modification or SC&C tall ball joint upgrade could reap the benefits of the AFX spindles, without effecting the geometry already in place.

To make this easy,if you`ve got a car they fit then they`re your top choice,period. I`d say the same thing even if we weren`t their biggest dealer.
