StopTech Big Brake Kit: 4-Piston Red Caliper (Rear) / 355mm x 32mm Slotted Rotors (996 Carrera)
Designed to fit:
- 1999 - 2004 Porsche 911 Carrera 2 / 4 (Rear)
NOTE: verify fitment with your wheel set-up by using the Wheel Fitment Guide.
All kits include calipers, two-piece rotors, pads, stainless steel brake lines, and all mounting hardware required to replace the front factory brakes. This system for your Boxster S or Cayman S replaces the factory components with a lighter package reducing upsprung weight while increasing thermal capacity through larger and thicker rotors. This kit utilizes 14" rotors over the factories 12.5" rotors and also expands the thickness to 32mm from 28mm.
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 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.
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
Patented AeroRotors and AeroHats that offer up to 80% 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%.
- 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
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 Line Kits
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 Street Performance Brake Pads
StopTech Street Performance Brake Pads are included in all Big Brake Kits besides the track-only Trophy Race Big Brake Kits. StopTech Street Performance Pads are intended for high performance street driving as well as light duty track use.
- Aggressive pad for high performance street driving
- Para-aramid composites provide linear response regardless of pad temperature
- 100% positive molded for uniform friction material density
- Low dust formulation is rotor friendly and leaves wheels cleaner
- Scorched to raise initial cold effectiveness and ease bed-in
- 100% Asbestos-free formulas
StopTech is the high performance and racing brand from Centric Parts - a leading innovator of world class brake components and systems for production-based race cars and high performance vehicles on the street and track. StopTech was the first to offer balanced brake upgrades for production cars and remains the worldwide leader with over 700 platform offerings that dramatically improve overall braking performance.
StopTech was founded in 1999 with the singular mission of becoming the leading aftermarket manufacturer and supplier of high performance brake components and systems. The company founders sought to challenge the status quo in known brake technology, and set new paradigms for brake system upgrades. United by their passion for racing and high performance vehicles, the company quickly earned a reputation for quality and performance both on and off the track.
StopTech’s industry-leading technologies and materials - from rock solid calipers to ingeniously efficient heat handling rotors - have earned the company four patents and numerous industry honors over the years. In 2013, StopTech earned full ISO/TS 16949:2009 Quality Management System certification for the design and manufacture of automotive brake systems and components, allowing the company to supply OEM vehicle assembly plants directly in a Tier 1 relationship.
StopTech has been awarded the highly coveted TÜV approval on several big brake kits. StopTech kits successfully passed TÜV’s demanding series of tests that range from performance and durability, to proper fitment and ease of installation. Although TÜV certification is not required in all countries, TÜV approval demonstrates that StopTech’s Balanced Brake Upgrades meet the rigorous standards set by this respected German agency. StopTech Big Brake Kits have been awarded a Teilgutachten. The complete kit is certified to run on a particular application, so customers do not need to pay for further testing with the TÜV agency.
