Rear Big Brake Kit - Stage 1 - 2-Piece Ventilated Cross-Drilled & Slotted Rotors (306x22)

ECS introduces our own in-house engineered complete braking solution for your MkIV. This bolt-on upgrade replaces your standard 232mmx9mm rotors with massive 306x22mm vented rotors as well as upgraded calipers from the GLI/337/20th Anniversary edition. A larger diameter brake rotor increases braking force, much like a longer wrench will increase the torque applied to a stubborn bolt. These rotors are vented, cross-drilled and slotted for maximum cooling and cleaning efficiency. They're bolted to black anodized hats for a long-lasting, great look behind your favorite alloys This complete kit comes with everything necessary for a smooth installation. 2-piece 306mm ECS Tuning Tru-Float brake rotors, slotted and cross-drilled Rear 337/20AE/GLI brake calipers and caliper carriers with mounting hardware ECS designed caliper carrier brackets with hardware Exact-Fit Stainless Rear Brake Lines with Brackets We recommend pairing up this great upgrade with a quality ECS Front Big Brake Kit for maximum stopping power. **Please NOTE: QTY 4 .50mm shims are included in each kit to accommodate for manufacturing tolerances in rear trailing beam mounting knuckle thicknesses.
