I'm looking to buy wheels obviously and the ones I would like to get are 42mm offset. I read some where that ours was 40mm. Would that make a difference? They are 17" think they would rub?
96 w/ HS CAI(soon to be installed), timing @ 17, Naxos muffler, Eibach Sportlines, KYB GR2's all around(soon to be replaced w/ Motivational fronts), APC Clear corners, and Focus short throw.
B14 stock wheels are 15x6 w/ a 40mm offset. Anytime you increase the width of the wheel, you "should" go down in offset size so you don't get into rubbing w/ suspension components. Always good to stay within minus 5 mm(35mm) or plus 5 mm from stock(45mm), since 5mm is 3/16 of an inch in measurement.
The higher the offset, the more you are putting the wheel towards the suspension components.
