...is there any other tyre brand recommended for the Z3? I've been running continental sport contacts (summer) and conti winter contacts on my previous cars (an Audi a3 & an E91 3 series) with good results. I never had this tracking problem (car chasing the camber and irregularities of the road). Then again it might just be that the cars weren't prone to this. My Z3 is currently running Mythos tyres up front and Pirellis at the rear. Wheel geometry up front is within manufacturer's spec (recently adjusted) but rears slightly out of spec (and apparently NON adjustable). I'm hoping to fit a set of tyres that'll cure or at least *minimize the problem. Any suggestions?
