Having aftermarket Brembo Grand Tourism (#1B1.7009A) 332mm brake kit installled on the front axles has left me with an nice set of removed originally installed factory OEM (#34111161177) 324mm Brembo's. Does anyone have an opinion on the feasiblity of mounting those 324mm four pucks on the rear, replacing the small OEM two pucks? Would this affect the braking balance? I am not an engineer, just a tinkerer, nor have I inspected the mounting compatability, which might require fabrication outside of my capability.

I've had 8 pots and 6 pots where the 4 pots did as good a job if not better, You need to put the car on a track and really get the brake temp up to appreciate the differnce of a Big upgrade, It's too hard to do in traffic or on the streets, Unless it's a high speed chase!--) There just for looks in everyday traffic but they look good.

Reading all the articles on the referenced website was an education! For a non racer like myself, considering BMW's balanced design, the previous owner of my 840 wasted a lot of money ($3200) for the big brake upgrade. Of course I really like the look of those Brembo's peeking through the spokes....
