C5 Brake conversion
Have ordered the parts and will be doing the conversion on my track car next week. The car is an 88 with stock 17X9 wheels. Can anyone tell me if I am going to need spacers to make these wheels work. I will be upgrading to 11" wheels sometime in the future, but it is probably a year away.

On the early sawblades some people have claimed that they have fit. I've never been able to verify this myself. I know the later sawblades definitely don't work. I think you would need about a 1/2" spacer so the inside of the spokes don't hit the caliper. By the way it's not really the width of the wheel that causes the problem. If you switch to 17x9.5" A-Molds you'll be fine.

or maybe not!The 17" 1988 "salad shooters" will not work (IMHO) without spacers. The C5 calipers are much wider than the C4 and will hit the inside of the wheels.
The spacer/adapters are expensive. I picked up a nice set of Y2k wheels in C5 parts for sale at only about double the cost of the adapters

I bought my kit for VBP but have not installed. They told me that if you have a 17"x9.5 inch rim you will be ok but if you have an 8.5 inch wide rim you may have clearance problems. I know that 1990 corvette rims are 9.5 inches wide but in 88 they may have been 8.5 inches up front... I am not sure.

Your 88 stock wheels should be fine without spacers.
If you look at my front wheel you'll see the C5 caliper, and i believe the 88 thru 90 wheels were the same backspacing
