Rear Wheel Camber

DFW Tom · 04-01-2024, 11:33 PM

I’ve got a 2006 e85 with the M sport package, just replaced the rear tires and went from 255 to 265 for a more aggressive stance. The tilt inward looks a little more pronounced now, is it an optical illusion? I love the wider tires and the cornering is insane with Michelin A/S 4’s, and everyone knows the ride is incredible compared to the run-flats. But should I adjust the camber to level them better?

No. If you’re concerned that they’re out of spec, have the car aligned.

The spec for negative camber is pretty aggressive for the Z4. The wider the tires, the more you see it. I think is does put more pressure on the RTAB (rear trailing arm bushings. If you do not know for sure those have been changed, it is time. The inside edge of the tire will wear very fast. keep an eye on it.
