I'm going with the BRP modified Subframe with the rack and pinion and ls1 mounts, t56 cross member. Has any onever ever used c4 spindles and brakes (or arms for that mater) along with the the standard subframe? I have spindles, brakes, shocks, Arms, off of an 84 corvette and before I attempted to try anything wanted to know. What are the best arms to go with if I'm looking to use qa1 coil overs. Thanks in advance

what car?

i am also searching for similar info. Would a C4 spindle work with 2nd gen camaro arms?

Regarding both 1st and 2nd Gen F body cars-

I think with enough modification it could be made to work, but I doubt it is a direct bolt on, no matter how many aftermarket parts are involved.
The first item you need to concider is why you want a C4 spindle on the car. Is it for the look or bragging right of having a Corvette item on the vehicle, or is it a brake upgrade solution? Do you know what this spindle will do your geometry, track width, bumpsteer, and turning radius? If not, you might want to research those questions first, as they are much more important than whether or not a C4 spindle will bolt onto a pair of control arms.

I'll try and help you out and help you look for the some of the pitfalls you might encounter when trying to adapt a late-model donor spindle onto factory or upgraded aftermarket frame.

#1- ball joint taper. The C4 Corvette uses a different taper than any of the control arms offered for the 1st gen F body. 2nd gen might be closer, but more than likely not an exact match. The easiest solution would be using the C4 upper and lower ball joints, and fabricate a solution for mounting them to a set of factory or aftermarket control arms. SC&C uppers would do this job very nicely.

#2- Steering arm attachment to outer tie rod end. This is very lucky for the BRP modded subframe guy, as he has a front steer rack and pinion now. 2nd gen guys also use front steer. This will make it easier for both of you vs a factory 1st gen frame with rear steer and a steering box as the C4 spindle has the steer arm cast into the front of the spindle. I don't think the outer tie rods on any of these frames, no matter what mods have been done, will be in the correct arc for a good bump steer curve. Hell- they won't be the same taper, or even close to the right length, so this is just a minor set back. You will need to do some serious re-working to the steering geometry and components to pull the swap off. You'd need to check turning radius as well to make sure you can still park the car, or make a U-turn.

#3- Track width. You have no idea what this might do to your track width. (Neither do I, so don't feel bad.) It could make it too wide to fit your current rims, etc. Pin drop would be a factor here too. It may make the car too low to drive with the current wheel/tire package.

As you can see there are quite a few variables, but with some research, fabrication, and determination, you could install the spindles onto most any car. Please be safe in your execution should you decide to persure this.

Our AFX spindle is a great no hassle solution for this. It will work with the BRP subframe if it is for a 1st gen, and we will be releasing a fitment for the 2nd gen in the near future.
