Stop Tech Silver Caliper Big Brake Kit for 04-07STi


StopTech BBK 01/03-04 Subaru WRX STi Front ST-40 Trophy Anodized Caliper 332X32 Slotted Rotors


Intended for ultra-high performance street use. They are designed for street driven production vehicles. The Trophy Sport Big Brake Kits use the same STR calipers, AeroRotors and AeroHats found in the full-race Trophy Kits, but add silicone dust boots for extended service intervals and anti-rattle rotor mounting hardware for quieter operation. They also include StopTech Street Performance Brake Pads for high performance street and occasional track use. Trophy Sport Big Brake Kits are the ultimate street braking system.

*StopTech STR Calipers* * Stiffest aftermarket caliper available gives a consistent firm pedal * Fully machined and lightweight for track action * Hard anodized finish that is impervious to color change or fading * Fully forged and extremely stiff for firmer brake pedal feel * Meticulously engineered 2-piece design reduces flex * Patented, removable center bridge further resists yaw(flex) * Carefully selected piston sizes for precise torque output

*StopTech AeroRotors* 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. * Specifically engineered and patented AeroVanes for optimum cooling * Patented, billet 7075 aluminum AeroHats for improved airflow * Full-floating mounting hardware to eliminate pad knock-back * Optimized to provide even performance and consistent feedback * Hard-anodized hats are impervious to color change or fading *Hard Anodized 6061-T6 Billet aluminum Mounting Brackets with Stainless Steel Studs*

Application-specific hardware that is stronger than most competitors, with studs instead of the more commonly used bolts and hard anodized aluminum billet composition. * Hard anodized billet aluminum mounting brackets * Stainless steel studs secured with set screws for strength and durability * Fully machined aluminum or steel that is precise and strong * Application specific design for precise and proper fitment * All necessary hardware for easy installation

*StopTech Stainless Steel Brake Lines* Braided stainless steel lines reduce system compliance and improve brake pedal feel and modulation. StopTech’s Stainless Steel Brake Lines are D.O.T. compliant and designed to fit your vehicle. * Stainless steel braiding for lower compliance and extra protection * Provides quicker response * Firmer pedal feel * A variety of fittings for hundreds of applications * All necessary brackets and fasteners for easy installation * Better brake modulation * D.O.T. compliant

*StopTech AeroHats* 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 50 percent * Patented design with directional stand offs between the rotor and mounting bell * Increases airflow by 50%-100% over traditional 2-piece designs * Increased airflow reduces the temperature difference between the inside and outside rotor faces * Results in less distortion and better performance compared to other fully floating designs * Outer pad wear is reduced
