Personally my favorite bmw is probably the MKI M3's I loved the big boxy fenders on em and I am thinking about doing some work to mine to get the same effect for my lude, hopefully widen the fenders a little so I can get another inch of tire on there once I upgrade my wheels... 18x9's would look sweet on it plus traction would rock!

EDIT:Oh yeah I am prolly gonna go with BBS RGR's if I can find them in the right size
