Hey guys, I wanted to share with you another killer option for our M3.
Racing Brake, made these 4.5lb 4-pot calipers with quit change pads, two-peice rotors (front are 4.5lbs and rear 6lbs lighter than stock)! They do make a larger rotor setup, but I optioned for the std size because of my application. I'm building up an autocross car for STU out of my E90 and this is one of the many steps. The kit comes with lines and everything you need to install. They also give you a discount on pads if you buy them at that time.
Everything is hardness tested, build in dust boots, true float rotors w/ vented grooves, SS pistons, powder coated calipers, rebuildable...etc.
Here is the link and a few photos for you guys to drool over.
