I need a set of autox wheels and I was looking at some 15x8's with 32mm offset. Now, I know these will stick out past the fender, which is ok becausethat's the fast way anyhow I will be running springrates high enough so that I won't have to worry about rubbing. Tires will be 225/50/15 Hoosiers.

However, what's the backspacing on a 15x8 at 32mm? I want to make sure they aren't too close to an control arm or something.

Thanks.

 

that's a tough one. try IM 2fknfst - he runs 8" rims on his R with 3mm spacers I think. Not sure about the offset though.

 

2fknfst runs 16x8 mazda RX7 rims with 38mm (?) offset + the spacer. Ask him or BlackR for the exact offset on those RX7 rims.

BTW, why do you even need 15x8" rims? 15x7" not good enough? Surely, you can't squeeze 245's in there...

 

I'd rather stretch a tire over a 8" wide rim than have a bulge on a 7" rim. More precise handling and a wider contact patch with the 8"

16" wheel/tire is waaay to big. Heck, even a 15" is a little large for a FWD autox car.

 

can someone explain
what exactly is the offset of a wheel
how do you determine what offset you should get
when purchasing wheels
