And..... it's done. I "believe" I'm the first person to retrofit an X5M 6-piston big brake kit onto a G05.

Pedal feel..... absolutely do different
Braking feel...... absolutely no different
Looks/appearance? Different..... better.

Is it a worthwhile upgrade? Ehhh.... if nothing else, there's bragging rights I suppose.

Worthwhile note: If you're considering the same thing, make 100% SURE you buy a kit with calipers, rotors, caliper bolts, caliper brackets, and an OEM X5M brake wear indicator sensor.

Worthwhile note 2: The rotor locking bolts do not match up, so you cannot use one. No safety issues, but you need a centering bolt to line up the hub, rotor, and wheel. No need to remove dust shields. Brake lines match up with no issues as well.
