Are you driving 135i? If yes, you need camber plates for negative camber,
I tracked 135i for 6 years and in stock form that car was understeering like a bus.
I never used these tires but I hear they are very good when pushed hard.
Sticky tires need negative camber, especially on that car. I was running -3.5 front and -2 rear plus other suspension upgrades and only then I was able to use sticky tires and get all the benefit they provide.
If you are not tracking your car you are wasting really good tires.
For the street I would recommend bridgestones re 71 R tires.
Hope this helps
