I successfully installed factory corvette c5 rims and tires without major issue but I did have to use a dremel to take a bit of material from the centre of the rear rim to fit over the hub. i was happy with the look but with the offset they really sat inside the fenders. Then I got a deal on new tires that were a couple sizes wider front 265/40R17 and rear 295/35R18. The front was fine but the rears were hitting the bump stops. So I ended up buying 1.5” spacers for all 4 corners and it looks fantastic. Much better than without, they sit about even with the edge of the fenders now. Changes the entire look of the car, super happy with it.

Just thought I’d pass on the info for anyone looking to put C5 rims on their firebirds.

I got C7 rims on my 95 firebird, front 275/40ZR17 102W rear 285/40ZR17 104W, didn't need modification or spacers on mine but slightly smaller rears then yours.

I love the look of mine though, they are great.

The issue with the rear axle hubs being slightly larger than the front hubs is a know problem with the early 4th Gens. This was the result of GM pulling the 10-bolt 7.5/7.625" rear axle assembly for the 4th Gens out of the S10 pickup parts bin. The problem exists with 1993-1996 model years. In 1997 model year the problem was corrected by making the rear hubs the same diameter as the front.
