StopTech Big Brake Kits offer superior street performance.StopTech Big Brake Kits feature fully forged calipers with patented stiffening bridges, patented 2-piece AeroRotors for optimized cooling, braided stainless steel brake lines, performance brake pads, mounting brackets and all necessary hardware to make installation as quick as, well, stopping fast. StopTech Big Brake Kits were the first Balanced Brake Upgrades on the market, offering optimized brake bias to utilize all the traction available from all four tires. This history, combined with StopTech quality and durability, are just some of the reasons they are one of our recommended Big Brake Kit options.Performance detailsThe StopTech CalipersFully forged 2-piece calipers4-piston DesignLowest amount of flex and deflection among industry peers (including some monoblocks)Offered in a glossy black high temperature paint to ensure good looks throughout the life of the caliperThe StopTech Rotors2-piece Slotted AeroRotor designIncreased air flow thanks to curved, airfoil-shaped vanes and specifically shaped air channelsAluminum AeroHats that are lighter and increase airflow to the (hotter) outside face of the rotor by over 15%Optimized to provide even performance and consistent feedbackDesign ensures longer pad and rotor life due to enhanced cooling characteristicsBillet Aluminum Mounting BracketsBrackets made of hard anodized 6061-T6 Billet aluminumStainless steel studs secured with set screws for strength and durabilityFully Machined design to ensure precision fit and strengthAll necessary hardware included for easy installation StopTech Stainless Steel Brake Line KitsStainless steel braiding for lower compliance and extra protectionProvides quicker system responseFirmer pedal feelVariety of fittings to ensure proper fitmentAll necessary brackets and fasteners for easy installationBetter brake modulationD.O.T. compliant StopTech Street Performance Brake PadsAggressive pad for high performance street drivingPara-aramid composites provide linear response regardless of pad temperature100% positive molded for uniform friction material densityLow dust formulation is rotor friendly and leaves wheels cleanerScorched to raise initial cold effectiveness and ease of bed-in100% Asbestos-free formulas
