Offsets and Backspacing

**classicfirebirds** · 02-25-2007, 05:03 PM

I'm thinking of running a set of TT II's 17x9.5 front 18x10 rears on my '94 Firehawk. Can anyone help me out with the correct offsets and backspacing to minimize rubbing? I cant seem to figure out this whole offset measurement deal.

anything within 6-7mm of +50mm offset should make it perfect.

i should have different offsets for the front verses the bac right?

Sweet SS! I didnt think you could get 17x11 on the front of f-bodys, yours seem to fit quite well

if they're within that range, you're fine.
stock 17x9" are +50mm on all corners and fit nicely.
