I have a vendor telling me he thinks I can put the oem brembos (rotors and calipers) from the front of my '07 on the rear and then put a 6P caliper BBK on the front. I want to upgrade to 6P calipers on the front and 4P calipers on the rear, but can I actually do that? Won't that jack up the emergency/parking brake?

 

im no expert on something like that but im fairly sure the bolt holes wont line up and the rotors defenetly wont work. the rear e brake has a little drum inside the rear rotor...

 

Yeah, its def not possible to swap the rotors. If you did swap the caliper, you would need some sort of adaptor bracket, and the swept area is much smaller on the rear rotor, so it wouldn't be right anyway. No-go.
