c5 wheels on a c4

Ive got a 87 corvette, my question is what do you have to do to get c5 wheels to fit it. Isnt the backspacing different? Can i get wheel spacers to make them work?

Here is what you need. I haven't done it yet but I'm going to run my C-5 wheels on my 1987 C-4. I had them powdercoated black and I'm going to put a red pinstripe on the lip in the groove. here is the link.

Front and rear. The adapters are normally 3/4". Spacers are not recommended. Adapters are prefered because of wheel stud length, safety and stability. $.02

On my 86 I used 1" adapters to bring the C5 thin spokes out flush with the fenders with stock sized tires. Front and rear.

This is the only pic I have available that shows the fit with 1" spacers. I was having the WBO2 bung installed.

Your rears don't sit in at all? I put my 98' wheels on my 88 and the rears seem to sit in the fender a bit.

Hi, these 'wagon wheel' rims look good indeed! Wat tire size are you running on these C5 rims? (as they are 18" in the rear versus the 17"at the front) The most seen size is 245/45-17 at the front and 275/40-18 at the rear, yet these are quite different in size... Does that matter a lot?

Put C5 wheels and Firestone Firehawks from a 2003, on dad's 93 vert. They sat in too far on the rear. Did 3/4 in hub centric adapters on the rear, 1/8 in spacers on the front.

I put them on my 84. They did fit without spacers but did sit too far inboard. I ended up putting adapters as stated above.

The wheel mounting surfaces on the hubs of 88-96 C4s are 18mm further outboard than on the 84-87 cars. Therefore, what fits properly on a later C4 like yours will sit 18mm too far inboard on an earlier car like the OP's. The spacers fix that.
