Default rear oem bbk upgrade

I was thinking, if we have the 4 calipers up front, can we just buy the 2 calipers front from the non-f-sport and install the 13" rotors in the rear? You would just need to bend the dust cover.

Any parts guy here can check that out? (Is the non f sport front calipers aluminum?)

It would nice with those 4 calipers on and painted!

I dont think so because the caliper mounting points are different.

I wish it would be that easy, as they say easier said than done.

Brake balance will probably not be correct. Even though there are various numbers of pistons that can be used in calipers, there is also piston sizing that needs to be considered.
