Be careful with tyre sizes, I have read heaps re tyre fitment. What sort of flares do you have, do you mean the factory flares fitted to all 70 and later C3's, or do you mean fatter aftermarket type flares?

What backspacing  do the wheels you ordered have?  For 8" wide rims the normal backspacing for a vette is 4", you can go more backspacingand have the rims stick out but this can put unwanted loads on the rear wheel bearing.

The three things that may be a problem if you are running 295's on 4" backspaced rims on the rear of a C3 are:
1. The handbrake cables and brackets, this problem can be aleviated by relocating the handbrake cable or just using zip ties to hold them back.

2. The trailing arms might interfere, you will need 'offset' trailing arms that are available from several suppliers in the U.S. these just have a bit more of a kick in them and will clear fat tyres.

3. The transverse leaf spring, this can also interfere with the rim/tyre, there are a couple of ways to fix this problem. The cheapest is to get longer adjusting bolts and just wind the spring down more, these may or may not get you enough clearance. Otherwise you will need a shortened rear leaf spring, a spring place here may do it for you, otherwise there are a few suppliers of custom made short springs in the U.S.

Let us know how you go, and post pics!

What size tyres are you going on the front.

Cheers,
Cosmic
