I am using ST-Tech (KW) adjustable on my 2000 M5 and I am running 19x8.5 - 18MM - 255x35x19 & 19x10.0 - 25MM - 285x30x19. Car is lowered several inches front and rear. No rubbing. No mods. Very clean look. I can post pictures if you want it.
Had 5 people in the car and was going reasonably fast on a highway. No rubbing of any kind.
