StopTech - Performance Slotted 2-Piece Rear Big Brake Kit - Subaru 08-14 WRX / 10-14 STI

A StopTech Big Brake Kit represents the ultimate high-performance brake upgrades and gives vehicles that supercar look and feel.

StopTech Big Brake Kits exceed stock performance in two key areas: First, larger rotors increase heat capacity, allowing a driver to brake harder stop-after-stop with a reduced chance of fade. Second, stiffer calipers and stainless steel lines reduce system compliance, providing a consistent pedal feel and confidence-inspiring responsiveness.

The key, however, is to increase heat capacity and reduce compliance without upsetting a vehicle's stock front-to-rear brake torque ratio. That is why StopTech developed the Balanced Brake Upgrade design philosophy, which precisely apportions front and rear braking resources while factoring in vehicle weight transfer under braking. In contrast, a brake upgrade that adds too much front torque (as many do), will reduce your car's ability to maximize the traction available from all four tires, robbing you of performance. In addition, a system that uses too many pistons or pistons that are too large will make the brake pedal much more difficult to modulate, limiting a driver's control of brake input.

• The Stiffest
• Fully Forged 2-piece
• Opposed Piston Calipers

StopTech 2-piece calipers have the lowest amount of flex and deflection among 25 of the leading caliper models (including some monoblocks) from well-known manufacturers. This is accomplished using StopTech's patented bolt-in bridge, which is strong enough to stop distortion without sacrificing cooling through the top of the caliper. The standard StopTech caliper finish is a glossy high-temperature paint available in one of six different colors - red, black, silver, blue, yellow, and gold. Trophy Sport and Trophy Race Big Brake Kits use weight-optimized STR calipers finished with a deep natural anodized coating that resists fading and discoloration at extreme temperatures.

• Less vibration
• Less Noise
• Better pedal feel under extreme braking conditions
• Faster braking response
• Less pad taper

StopTech has developed several design innovations to improve rotor airflow. The patented 2-piece AeroRotors push more air thanks to curved, airfoil-shaped vanes and an air-channel that widens at the trailing edge of the vanes. StopTech aluminum AeroHats are lighter and feature directional stand-offs between the rotor and mounting hat that increase airflow to the (hotter) outside face of the rotor by over 15%.

• Specifically engineered and patented AeroVanes for optimum cooling
• Optimized to provide even performance and consistent feedback
• Longer pad and rotor life
• Hard-Anodized 6061-T6 Billet aluminum Mounting Brackets with Stainless Steel Studs
