Front tire rubbing w/ 20in wheels - The Unofficial BMW M5 Messageboard (m5board.com)

Hi everybody--I've had my 20in BBS LM wheels and Dinan stage 2 suspension for a few weeks now, and I've started to notice worse tire rubbing in the front on turning the steering wheel. I had no rubbing whatsoever when the suspension was first installed, but I guess the springs have settled over time. There is no rubbing with the wheels pointed straight ahead or over bumps, but when the wheel is turned to go around a 90-deg corner, say in a residential neighborhood or parking lot, I hear a nasty rub from the outside front part of the front tire against the inside plastic fender liner. The liner seems to be smooth and flexible, so I assume I'm not doing a lot of damage to the tires, especially since it occurs during 20mph maneuvers, but it sure is annoying. Anyone else have this issue? Suggestions? Thanks.

Could be a problem with one of your front Dinan Springs. I know a few members have had spring defects where the spring compresses and doesn't fully rebound. If the spring doesn't rebound completely you could definitely have some rubbing.

what size are you front tires?

Overall rolling diameter is the same as stock--255/35-20 PS2s in front. The LMs do require a 10mm spacer in front to clear the struts, so the wheel is pushed further out than stock--I think by 12mm or so.
