All of this just so you can run some original ZR1 wheels? I know we must be missing something.

Hey Fellows, after reading the replys to this thread.. and I do say you guys sure know this stuff. Is it safe too assume that if I replace the rear spindles on my 1987 corvette with a set of 1988-1996 spindles I would be able to use my 11x17 wide rear rims with out using any spacers?? or is there other things that I would have to change?? thanks, gary

no , thats pretty much it. i have the wheels, rear axle , a shop that can do the work but didnt want to go that direction yet, but its looking like it would be easier in the long run .

gman35

well if all I have to do is change the spindles.. I will be looking for a set of 1988-1996 rear spindles.. does anyone here have a set they would be willing to sell?? thanks, gary

That's a ton of time and money spent to ruin a perfectly good IRS, just to run a particular set of wheels. Whether it's worth it is all in the eye of the beholder, of course. But damn, I'd just spend some money on the flares or buy some wheels with the offset you need (probably 50mm, like I run). Go crazy and get a whole set of 18x11s and run a square setup. People will compliment your car!

In post #14, WVZR-1 notes that this spindle swap may not be a plug-n-play procedure. And from the little scanning of the big doggie mod that I did, there is machining involved.

the wheels aren't available in aftermarket that i want, yes it would be easier to concede and buy a wheel that would fit, but i want a particular wheel which i found and got a smoking deal on , 500 hp and nos doesn't work well or long in front of a d36, in the end i will be using a solid rear axle, i can set the distance etc when putting the in the axle assy , brackets are easy , trans cross-member is easy , in the end i have exactly what i want a quick reliable rock solid c4 corvette. it all cost money in the end, its just how much and where you spend it .

I feel you! I bought a set of ZR1 Fikse wheels because I got a good deal years ago and machined the parts to narrow the 1990 axles... fast forward I bought the correct wheels and now I am sitting on a set of Fikse ZR1 rims I doubt I will ever use....

If I ever do it again I will get wheels to fit the car and not make the car fit the wheels....

It is recommended that one not make any corrections other than body work to compensate for the misalignment.

Anyways, you can only see one side of the car at a time....

I have seen this in an old thread a long time ago on the forum here. A member purchased a car that had been curbed on one rear wheel and when the parts were bent, replacement early parts were used and it caused the side to be much more inboard. Just thought id mention that it might be worth looking into before moving things over and/or adding spacers.

I also have an 87 C4 that has the rear end offset to the drivers side. No frame damage and no apparent trailing arm or other damage. The driveshaft runs very close to the tunnel at the rear but the Engine/trans are centered up front. The car drives straight , no pulling or wonky issues with driving. Could this be the body issue that someone mentioned? Oh, and the wheels are centered in the wheel wells, not canted at all.

I just put +36 mm ZR-1 repros on my 86. It accentuated the offset to the driver side... I just had it aligned and camber is set at 0. It makes the offset more noticeable for sure, but I dont care. Car drives perfectly down the road....

I may be missing something here so I'm going to ask the question. If there is a difference in the overall length of hub assembly between early and late C4's (which I assume is true based on some of the earlier statements), if you sit them side by side on a flat surface is the depth where the spindle washer goes the same on both or close?
If they are different, wouldn't it require either a longer half shaft or spindle to compensate for that increase in length?
