Guys at the track said this is a normal issue with 4s and I should try Eagle F1s or the Cup 2s... unfortunately, those tires are not made in the sizes needed for the staggered M340i.

Any luck upgrading wheels?
I was going to potentially go with Cup 2s next summer, if you use the stock staggered set up wheels, they have fronts in the OEM size, but for the rear you have to go down from 35 to 30 side wall. This will also drive a reduction up front to 35 to make sure you have the diameters close enough to not freak out the xDrive system.
