Will the M sport calipers from the F30 fit on 345x32 rotors?
I am thinking about upgrading my calipers and was wondering if the calipers would fut the rotors I am running now.
I want to get rid of the heavy steel ATE calipers I have for now

Would you say 370x30 is better than 345x32?

Also how is the performance of the sport/performance package?

Can they handle track use or should I be going aftermarket like brembo or stoptech?
