I'd strongly suggest the Ireland fixed camber plates. The added 3/8" on top of the springs really puts the car back into a decent travel over bumps & potholes. I would have pulled the bav auto springs from my 535 if not for the camber plates. The plates also help initial turn in.
Another not so great point about the bav auto springs with big wheels; 18's are gonna ride like crap. I think my 16" winter wheel & tires ride much better than the 17" m5 wheels. The 235-45-17's do not have much sidewall. I never bent or scuffed any of these forged rims, surprisingly. The 225-50-16's ride much better.
I also have the single pot 850 front brakes. Hawk HPS pads are on there right now, & they are greatness. Mintex pads on these brakes are very messy, but stop the car well from cold.
