2008 BMW 135 with OZ Ultraleggera

Suspension/Fender Mods/Camber:
Car is running KW Variant 3's at the lowest setting in the rears, almost lowest setting at front (level on the street)

Had the rear fenders rolled a little when I got the wheels put on, no rolling on the front

Notes:
Rears rub on medium to large bumps at speed, also while in sweeping corners at high speed the rears rub. I can get the fronts to rub a tad if I brake hard while turning (stupid idea but I did it to test).

Going to try raising my KW's a little. If that doesn't stop the rubbing, I'm going to have to roll the rears out more, and roll the fronts as well.
