Well, while I do appreciate your help, I must say I do understand what +/- offset means. I just wanted to know these specific setup will work on E92 due to high offset.
It seems that tireracks's site has variety of rims/tires choice for 335i sport package and offsets scatter from anywhere inbetween 30 to 40 which is very close to the offset that I mentioned above. As I put down on the #1 post, I know that these set up will work if offset is right.
I just wanted to be extra curious/careful because, 1) E90 and E92 has 5mm difference in rear fender width, and 2) if I do decide to buy, it will be several thousand dollars I'm talking.
So my question is... will these setup work with just merely spacer?
