offsetting
 

what are the bonus's of offsetting i know you gain grip / handling but does it help out any other way?
im ordering RPF1's and was wondering how i should offset
17x7 w/ 17x9?
17x7.5 w/ 17x9?
STOCK? (17x7 front 17x 8.5 rear) (why go with stock?)
the car is lowered so i am trying to go with the stock tire to prevent rubbing etc. im just wondering if addinging an extra ".5" width will do anything positive
thankyou for all advise .

Hmm well, not sure if "offsetting" is being used properly here...but to try an answer your question.

We'll look at the rear wheels...stock is 17 x 8.5 +65 offest...yes, the RPF1 is only .5" wider, but it is also +45 offset, which means the outside of the wheel extends an extra 26mm. This means that the track of the wheel/tire is pushed out, which can be good, but then you have a chance of rubbing over large dips or full compression if your fenders aren't rolled and your rear bumper tab is not relocated.

If you run stock tire sizes on 17 x 7.5 +48 and 17 x 9 +45 I think you should be ok, but the rear may rub slightly.

Thankyou, and im not familiar with rolling fenders and relocating bumper tabs
how much does it cost and who is willing to do it? (tunning shops, body shops (macco?) )
