Rotors and calipers

[Mutant107]

Will the new calipers from the M56 fit the M45? Looking at changing out the brake system

I doubt anyone would know. You will need to take some measurements to find out.

I have always been curious about this too. I "assumed" that they were the same size as the G-Series BBK's??

subscribed for more info on this as well.

i just upgraded mine to cryo treated rotors and HPS pads, but this is always good to know.

The new M series calipers has Infinite on the side, TW dealer parts department their no help they can only look up parts according to VIN # . I'm assuming if I get the Rotors and entire brake system from the new M37 or M56 one should work. One problem they claim is the special order can not be returned if it doesn't fit, anybody has knowledge on this subject please reply.

The old BBK from the G37 would fit on our older gen M's, however with the stock wheels you would have to run spacers to get the rim spokes out past the caliper.
Might be similar for these new ones designed for the new M
