Have some full on Brembo m4 calipers for sale. 34mm pistons. Great calipers and only ever done 1 track day and some road use. The bite on these is unreal. In awesome condition comes with part worn pads. £360
Can't take some now as they are in my storage unit. But here are some taken 2 weeks ago. I assure you they are in great nick. Bike is well taken care off
