Will 17" 50mm offset work on the 818s? The rims are 7.5". I assume since the rims are not that wide that these will fit with no spacers. I'm going with 215/40r17 front and 225/45R17 rear. I have not assembled the spindles yet and need to know if I need extended studs or not. I'm thinking that the wheels will probably be recessed in the fenders a little with this offset. Anyone with any experience with this size offset?
