im will be lowering my e with eibach spring soon but i also with be getting some bigger rims as well. I cant decide which offset i should get. The rims are 20x8.5 with either +35 or +45. I thought i would get the +35 but im worried about them sticking out to far and rubbing the fenders, and with the +45 im worried the back of the rim will rub the inside of the wheel well or strut, but what i thought i could do is get the +45 and maybe a 3 to 8mm spacer to push the rim out a bit if it rubs on the the strut or well. Any info would be appreciated.
