FS: Stillen Master Brake Cylinder Stiffner
I am running a JBT BBK...6 piston front and 4 piston rear. I did notice a difference on braking. It helped out when stomping on the brakes...I didnt get to experience the full potential because I bought it for my track days with my supercharger but didnt get a chance to actually try it out because my motor blew...
still available!
