I polished these things myself last winter. One rim has a little warp in it, but it's nothing you can feel while driving.
No curb rash. If you want to put these on an E36, you don't need hub rings!
Anyway, they're 17x8 and 17x9. Offset is around 20 front and 22 rear I believe. 5x120
The front rims have brand new BFG KDW's on them and the rears should be replaced.
$1600 (I just paid $450 for tires)
