Just installed a set of factory M parallels on our "new" (three days old for us) '94 750iL. Wheels are 8" in front (20mm offset), and 9.5" in rear (25mm) offset. Tires are Pirelli PZero in 245/40/ZR18 in front and 275/35/ZR18 in rear. Oh my God! The car now looks incredible. No spacers, no fender modifications, no clearance problems. I'll post pics as soon as I get a chance to shoot some.
