Stage 2 Slotted brake upgrade with slotted rotors for the 2004+ Subaru WRX includes StopTech stainless steel brake lines for front and rear, 3 bottles of Motul RBF600 brake fluid, StopTech Street Performance brake pads for front and rear, and StopTech slotted rotors for the front and rear. StopTech Street Performance is a very similar compound to Axxis Ultimate, except that it has a ceramic heat shield between the friction material and backing plate to help prevent heat transfer into the caliper and brake fluid.
