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.
