Here's an early Christmas gift you should buy for yourself
FIKSE Profil 10

19"x10" offset 25mm weight 23lbs REARs

It came out of an 2003 E46 M3, the wheels is in very good condition, no curb rash or bends. They cost around $5000 new.
The wheels was ordered specifically for E46 M3 but, I think it should fit E90 M3 or many others. Also please do your own research on the fitment. PM me if you have any questions $2750 shipped obo
