StopTech® Big Brake Kits are the ultimate high performance brake upgrades, giving vehicles that supercar performance, 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 reduced chance of fade. Second, stiffer calipers and stainless steel lines reduce system compliance, providing 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.
Every StopTech Balanced Big Brake Kit is engineered to produce that optimal balance using caliper bores and pistons specifically selected and tested for each vehicle application. This is what sets StopTech apart from off-the-shelf solutions.
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.
Reasons for a StopTech® Big Brake Kit
Features and Benefits:
Balanced Brake Upgrades® with optimum brake bias offer the shortest stopping distance with the best pedal feel.
Patented AeroRotors® offer the best airflow available for better cooling, less fade and longer rotor and pad life.
StopTech® provides the stiffest fully-forged aftermarket calipers with patented, removable bridges that provide better clamping under hard braking and less pad taper.
StopTech® Big Brake Kit components are made in the USA in a 70,000 square foot California manufacturing, engineering, and R&D center.
Choosing the correct StopTech® Big Brake Kit
StopTech® offers a number of different Balanced Big Brake Kits® for a variety of vehicle applications.
StopTech® Big Brake Kits offer superior street performance.
They 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 complete the installation. 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.
Trophy Big Brake Kits
For ultimate track racing performance StopTech offers Trophy Race Big Brake Kits, with naturally anodized lightweight components designed to survive the rigors of racing. Trophy Kits feature fully forged, lightweight STR calipers, 2-piece AeroRotors®, braided stainless steel brake lines, mounting brackets and hardware. The MAX Float hardware allows for the greatest amount of float between the hat and rotor. These Trophy Race Kits are used on many of the top competitors in the SCCA Pro Pirelli World Challenge Championship as well as in Grand-Am and other race series.
Ultimate street performance is obtained with a StopTech® Trophy Sport Big Brake Kit. The Trophy Sport Big Brake Kits are designed for street driven production vehicles and use the same STR calipers, AeroRotors® and AeroHats® as the Trophy Race Big Brake Kits, but add silicone dust boots to extend service intervals and anti-rattle rotor mounting hardware for quieter street operation. Trophy Sport Kits also include StopTech® Sport brake pads for high performance street and occasional track use. They are the ultimate street braking system.
1-Piece Rotor Big Brake Kits
StopTech® 1-piece rotor big brake kits offer the best performance from a 1-piece rotor upgrade system. Designed for street driven production vehicles, 1-Piece Big Brake Kits include the same forged 2-piece calipers as the StopTech® Big Brake Kits, as well as StopTech® Stainless Steel Brake Lines, StopTech® Sport Brake Pads, application-specific caliper brackets and hardware. The difference is in the use of larger than stock 1-piece rotors, which offer the most value to those seeking better performance than their factory setup.
StopTech® Big Brake Kit Components
StopTech® calipers are available in 6-piston, 4-piston and 2-piston configurations, depending on vehicle application.
The Stiffest, Fully Forged 2-piece, Opposed Piston Calipers,
StopTech® 2-piece calipers have the lowest amount of flexnd 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.
Stiffer Calipers Offer:
Less vibration
Less Noise
Better pedal feel under extreme braking conditions
Faster braking response
Less pad taper
Patented AeroRotors® and AeroHats® that offer up to 61% greater airflow
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%.
Benefits of StopTech® AeroRotors® and AeroHats®:
Specifically engineered and patented AeroVanes® for optimum cooling
Optimized to provide even performance and consistent feedback

Required Pre-Purchase Fitment Check: Vehicle-specific wheel fitment templates for StopTech® Big Brake Kits
To help identify whether your existing wheels will fit over a StopTech® big brake kit, download the wheel fitment template for your vehicle and follow the instructions to verify clearance before you purchase. While wheel clearance is completely dependent on the diameter, offset and spoke design of your wheels, a general guideline is that StopTech® kits usually require the following:
