STM Front Drag Brake Kits for 2005-2021 Subaru WRX and STi allow you to ditch the weight of your big, heavy stock rotors and calipers and clears room to run 15" wheels and slicks for drag racing applications and lose almost 50 pounds. We all know less rotating mass is the best way to free up power!
More Info:
The STM brake kits include Wilwood calipers and your choice of standard rotor or the lightweight scalloped rotor, custom STM aluminum mounting brackets, black anodized rotor hats, STM brake lines and all mounting hardware. The rotors will ship pre-assembled to the hats with safety wire as pictured.
The scalloped rotor is 2.7 pounds lighter than the standard rotor and is recommended for cars that see more miles on the drag strip than on the street. The scalloped rotor is not a street rotor.
• This brake set-up is specifically designed for drag racing
• This is not intended for constant, on/off braking as in road-racing or autocross
• Will clear most 15" wheels
