i'm getting c5 wagon wheels that i want to put on my 67 camaro to be able to clear new disk brakes i got for the front. I am pretty sure i will need to run spacers but not sure how much. Wheels are 2 17x8.5" and 2 18x9.5"
Anybody have any idea?

 

Probably around 2". The 1st gen cars should need about the same amount of backspacing as 3rd gens, right?

 

i thought it was somewhere around 2" but still not sure on exact. And yea, just looking at the wheels on my bird and camaro they have about the same backspacing.

 

i don't seem to be able to find the backspace specs for the wheels i got. I found that the front wheel got 56mm offset and the back ones got 61mm offset. I was reading the wheel sticky but not still not sure on how to convert those two into backspace numbers. anybody else have any ideas on how to fit the wheels?
