I've got a 2017 430i convertible with base brakes (312/300 rotors) that I purchased after it was returned from a lease. The rear rotors have been overheated at some point in their life. I'm considering upgrading to the M Performance brakes. My research has generated a few questions:
- I have the 18" staggered wheels. Will the performance brakes fit inside them? Having just installed new tires, I'm not interesting in upgrading to 19" wheels at this time.
- The kits all have red/orange/yellow calipers, but I'd prefer blue. Is there a car that had the 370/345 rotors?
- I've done some ebay searches, but none of the vendors list the rotor diameter with their so-called M Sport or M Performance calipers or sets. How can I determine if these are the right calipers for the 370/345 conversion?
Thanks in advance.
