Fitment

  • 2022-2026 Subaru | WRX

Description

STM Rear Drag Brake Kits for the 2022 Subaru WRX 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. Save 32-35 pounds of rotating mass!

Vehicle Fitment:
2022 Subaru WRX
• Deletes the E-Brake

More Info:
The STM brake kits include Wilwood calipers and your choice of standard rotor or the ultra lightweight scalloped rotor, custom STM aluminum mounting brackets, STM spacers, 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.

This kit will also remove the rear parking brake for additional weight savings. Again, this is designed for drag cars only.

The scalloped rotor is 1.15 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.

Installed pics coming soon!
