6-piston front BBK, 4-piston rear dual-caliper BBK - Full installation

Special thanks to "dentprotony@gmail.com" for supplying all the parts to the rear BBK

I did the fronts years ago here: https://g05.bimmerpost.com/forums/sh....php?t=1779038

But why not document it again? Got the wheels back from powdercoat, refinished the (front) calipers in red, and decided to go a completely different direction with it.

the new "look".

Yes, it is in loading mode. In sport mode, it does not rub at all.

Wheels are 22x10.5 front, 22x12 rear.
Tires are OEM sized 275/35/22 front, 315/30/22 rear
Tires are Continental Sport Contact 7s - The tires with the widest treadpatch on the market, so they don't look "stretched" over the rims.
