I have a chance to pick up a set of C4 Corvette wheels for a pretty good deal, wondering if they'll fit on my '93 without sticking out a lot? I believe they're 8" front wheels, 11" rears. Currently set up with P245/50R16 for the front and P295/50R16 on the rears.

 

Check above FAQ sticky ...

WHY WON'T MY NEW WHEELS FIT OVER THE REAR HUBS ON MY 4TH GEN?

The 1993 to "late" 1996 4th Gen F-Bodies have a larger hub on the rear axle than on the front spindles. The rear axle hubs are about 0.03" larger in diameter than the front hubs. This problem was corrected in late 1996 model year or possibly in early 1997.

As a result, if you buy C4 or C5 wheels, or if you buy 1997 or newer F-Body wheels, they may not fit on the rear hubs of your 1993-1996 F-Body.

The solution is very simple. First, DO NOT FORCE THEM ON WITH THE LUGS! Very dangerous, and you may not be able to get them off. You need to lightly sand or grind (e.g. - Dremel) the inside diameter of the hub hole in the back of the wheel. Don't go nuts.... just remove enough metal so the wheel cleanly fits over the rear hubs, with no interference.

Think about doing this to all 4 wheels, so you can "rotate" the tires in the future.

This will not harm the wheels.... you are taking off the thickness of a sheet of paper. Just be sure you do a neat, smooth job. This will also NOT affect the centering of the wheels on the hubs. The 4th Gen wheels are "lug-centric" - they are centered by the conical lugs, not by the hubs.

 

I DID check the faq, and I searched as well (although the search engine on this board is largely worthless), but whether or not the wheels will fit over the hub doesn't tell me diddly squat about whether the wheels will stick out from the car...

 

Exactly what year C4 wheels? I don't think there was ever an 8.0" wide wheel on a C4. The only 11.0" wide wheels were the 17x11's on the Corvette ZR1 and the 1996 Grand Sport. Each of those have different backspacing.... the small offset wheels will stick out and the 50mm offset wheels MAY require the modifications described in the FAQ.

To get an answer, you have to provide the correct width and offset of the wheels.

 

Most people on the board dont know about the FAQ that has been establish and you did not state in your original post, that you had already looked there... I just posted what I knew about C4 wheels.. I did not have the time to look over the whole FAQ reguarding your question...

So, dont look for me to assist anymore..
