Rotora Subaru Wrx 02-04 Brake Kit; 4 Piston Front 330X24 1Pc Drilled Slotted [MP# RBK1101]Fully cast and CNC machined to ensure the highest quality; Rotora?s high performance brake system enables superior brake modulation while improving overall pedal feel to ensure equal distribution of weight transfer when braking. To achieve this proportional front-to-rear brake bias, Rotora?s 2-piece cast aluminum calipers are fine tuned by increasing the clamp load to the optimal level while utilizing the stock master cylinder to retain overall front-to-rear brake bias. Rotora?s high performance brake system is comprised of a set of 1 or 2-piece cross-drilled/slotted or slotted directional rotors (295-355mm), a set of high performance (2, 4, or 6-piston) calipers, carbon steel (S45C) mounting brackets, Rotora ceramic friction material race pads, and stainless-steel braided brake lines (D.O.T. compliant). All Rotora brake systems are direct bolt on replacement with minimal modifications required. Fits Rotora Subaru Wrx 2002, 2003, 2004.
