Wanted to know if you can fit a 17x8 wheel with 5 inch backspacing all the way around on a 69 camaro. I know most people go with 4 3/4. The wheels I like only come with 4 inch or 5 inch backspacing. I know 4 inch will not work but the 5 might. The car will have a full hotchkis suspension with 2 inch lowering springs in front & 1 1/2 lowering springs in the rear. It will also have baer brakes all the way around. If they will fit I was thinking of running a 235/45/17 for the front and a 255/45/17 for the rear. Thanks for any help

After doing a search(s) and reading thru 50+ messages, info on 5" bs is somewhat limited. Below are some tidbits I've gleaned:

From Chevy High Perf mag(issue was Jan 2001), they say the following is max for 1st Gen
FRONT

15-inch
Backspacing: 3.75
Wheel: 7.0
Tire: 225/55

16-inch
Backspacing: 5.0
Wheel: 8.5
Tire: 245/50

17-inch
Backspacing 5.0
Wheel: 8.5
Tire: 245/40

REAR

15-inch
Backspacing 4.875
Wheel: 8.5
Tire: 28x10.5

16-inch
Backspacing: 5.5
Wheel: 8.5
Tire: 255/50

17-inch
Backspacing: 5.5
Wheel: 9.5
Tire: 275/40

Also, this site is handy for calculations:

I have the exact setup you have as far as suspension is concerned and hope(pray) that 17x8 5bs will work. Ordering American Racing 200S wheels that only have the 5bs available
