Add stopping power, better brake modulation and better brake thermal capacity with installing StopTech's ST40 big brake kit!  With a much stiffer as well as lightweight 4 piston brake caliper, you can guarantee your stopping distances will be shorter.  We also guarantee that the aesthetics of your BMW will be better as well with 5 different caliper color choices


This kit includes all the pieces to install big brakes on the front of your E46 M3 including stainless brake lines, aero vented rotors, fully forged calipers and slotted rotors.


Benefits of installing StopTech big brakes include the following:

- less brake noise (with street pads - race pads WILL make noise regardless)

- less vibration through the caliper

- better pedal feel under extreme braking conditions

- faster brake response

- less pad taper  

- patented 355mm x 32mm aero rotors and hats provide up to 80% greater flow compared to stock brake components


***Yellow & blue calipers may take longer than the standard (red, silver & black) colors***
