I have the same problem, my tracking is badly out as well as my camber i think. I'm about to fit a 35mm drop as well. the car pulls to the left quite badly but they have said my tracking was ok, i can see its out though just by looking. I would say its either a bad tire or something to do with the wheel geometry i will see what they say when i take mine in and get back to you, sounds like we have the same problem
