CA: Chassis, Brakes, Suspension & Steering Upgrades

StopTech was founded in March of 1999 with a singular mission: to become the leading manufacturer and supplier of high performance brake components and systems. United by their passion for racing and high performance vehicles, the founding staff sought to challenge the status quo in known brake technology, and set new paradigms for brake upgrade systems.

In service of the mission, and as a direct result of our ongoing brake research, StopTech has to date received three patents in brake technology and has one patent currently pending.

StopTech is the first aftermarket brake company to offer balanced front brake upgrades, engineered to dramatically improve overall braking performance while remaining compatible with the stock OE rear brakes. This has significantly advanced the state of art in aftermarket brake upgrades.

StopTech is now the worldwide leader in Balanced Brake Upgrades™ for production cars, with over 277 platform offerings. The company consistently wins braking contests performed by independent publications, and is now the dominant, preferred brake system in the SPEED World Challenge® Touring Car Series, the most competitive, production based sprint race series in North America. The company also participates in Grand-Am® Cup, the premier production based endurance racing series in North America.

Core competencies: StopTech engineers and manufactures high performance brake rotors, calipers, DOT compliant stainless steel lines, and brake upgrade systems for the racing and performance street markets. The company distributes OE aftermarket rotors, brake pads and brake fluid. StopTech's ST-40 and ST-60 calipers are manufactured using a squeeze-forged process.

Caliper bodies, hats, and brackets are machined to ISO standards at StopTech's manufacturing facilities in Torrance, California using the latest CNC machines that feature active tooling.

StopTech has received the prestigious TüV approval in Europe for a number of its offerings, and has been selected as the exclusive brake supplier by a major OE aftermarket division.

The future vision of StopTech is to maintain focus on its original mission. In doing so, the company will continually innovate significant improvements to brake technology for street and racecars, for enthusiasts and professionals alike.

If you already have a Stoptech ST40 4 piston caliper set up on your car, you can now upgrade it to the ST60 6 piston caliper./

StopTech has recently announced the ST-60, a six-piston, squeeze-forged caliper for premium luxury, performance and competition vehicles. Certain to be prized by the race engineer, discriminating performance enthusiast and aficionado of automotive excellence, this caliper offers the best performance available from a six-piston caliper upgrade.

Whereas competitors may provide high-tech products to race teams and less-expensive products to their street users, customers purchasing a StopTech Balanced Brake Upgrade® will receive the exact same ST-60 caliper design that has been tested for two seasons in punishing SPEED World Challenge GT-class competition on the #28 LG Motorsports Chevrolet Corvette and contributed to the car’s two race victories during 2005.

Attractive Styling
The ST-60 caliper’s longer body fills the space in larger wheels and looks great when paired with larger-diameter brake discs. Side contours clearly show the six-piston design, while the tapered ends and enclosed cross bolt features provide a sleek, smooth appearance and a shape that is easy to keep clean.

Patented Technology
The ST-60 uses StopTech’s patented bolt-in bridge technology, which reinforces the caliper and virtually eliminates distortion, helping make the ST-60 significantly stiffer than any competitive six-piston caliper benchmarked to date. The bolt-in bridge allows changing pads without disturbing the caliper’s mounting and provides slots to enhance cooling airflow through StopTech’s patented AeroRotor®. A feature at each corner of the caliper protects bleed screws and crossover tubes from damage by foreign debris or carelessness during wheel removal and installation.

Correctly Engineered Applications
A wide range of piston sizes allows StopTech’s engineering staff to tailor the ST-60’s force output to the specific requirements of each Balanced Brake Upgrade application. Engineering the correct distribution of brake torque between the front and rear axle of a vehicle provides the shortest braking distances, a result that has been shown time after time as StopTech-equipped vehicles have outperformed competitors in magazine tests and racing. Furthermore, correct caliper piston sizing ensures a firm brake pedal feel. Combined with the stiffness of StopTech’s caliper designs, braking response is consistent and linear, giving drivers ultimate confidence.

Quality Manufacturing Processes
StopTech's ST-60 caliper is manufactured using a squeeze-forging process in which pressure is applied during cooling, producing beautifully finished, high-density caliper bodies without porosity. All finish machining, assembly and testing is performed at StopTech’s facility in California, and every finished caliper is tested to 2500 psi.

Versatility
The StopTech ST-60 caliper can be used on rotors ranging from 328mm (12.9 in.) to 380mm (15.0 in.) in diameter and from 28mm to 35mm thick. The ST-60 uses a standard pad shape, which is readily available in more than 15 street performance and race friction compounds. The larger pad volume compared to StopTech’s ST-40 caliper provides greater brake pad life, whether in endurance racing or paired with today’s heavy luxury vehicles in street use. Differential piston sizes minimize pad taper for longer pad life and a firmer pedal feel, while dust boots are standard for reduced maintenance in street applications. Titanium backing plates are available for extreme applications to reduce heat transfer by radiation and conduction from the brake pad to the pistons and caliper body.

Balanced Brake Upgrade Kits
Balanced Brake Upgrade kits include two piece floating, directional AeroRotors with 7075 T-6 directional billet aluminum hats, calipers, brackets, street performance pads and DOT-compliant stainless steel brake lines. All kits are a direct bolt-on replacement of the stock front system with little or no modification required to the chassis or suspension.

StopTech Balanced Brake Upgrades incorporating ST-60 calipers are ready for shipment to customers, with 21 Balanced Brake Upgrade part numbers covering 34 vehicle applications available now and four more currently in development. Owners of such premium and performance vehicles as the Audi S4, BMW 5 and 6 Series, Dodge SRT-8 , Nissan Skyline GT-R R34, Porsche 911 can benefit from this outstanding new development.

StopTech LLC, located in Torrance, California, manufactures high performance brake systems and components for production cars and production-based racecars. The company is the leader in Balanced Brake Upgrades for production cars and has three patents in basic brake technology and one other pending. With a worldwide network of resellers, StopTech’s product line includes Balanced Brake Upgrades for approximately 450 applications, two-piece Direct Replacement AeroRotor Kits, braided stainless-steel brake lines and slotted and drilled original-dimension rotors. StopTech also stocks a wide range of performance brake pads. The company’s website, www.stoptech.com, is a clearinghouse of performance brake information, and provides details on StopTech products.
