Improved cooling and heat capacity means less fade

StopTech has incorporated several design innovations to improve rotor airflow, cooling and heat capacity. The ability to absorb and dissipate heat is essential to brake system performance.

Benefits of Improved Airflow

  • Less fade
  • Longer rotor and pad life
  • Beter performance

STOPTECH AEROROTOR®

AeroRotors are made using StopTech's patented vane design and our proprietary cast iron formula, which was specified with durability in mind. StopTech has had several sets of rotors run entire 24 hour races on winning cars. StopTech did extensive testing before settling on our final top-secret formula. To test rotor durability, we rented the California Speedway and ran a heavily weighted down car with StopTech rotors on one side and a competitor's rotors on the other. In this test, StopTech rotors were approximately twice as durable as the competitive rotor.

The patented AeroRotor® features curved vanes with innovations on leading and trailing edges. The uniquely designed vanes inside the disc optimize airflow through the rotor. This improved directional design minimizes turbulence and flows more air than any rotor tested. The result is up to 80% better airflow over original equipment rotors and 10-30% better airflow than directional vaned racing rotors currently available.

Aerorotor vane design

STOPTECH AEROHAT™

StopTech's hats and brackets are made with a special type of billet aluminum that was designed for the AeroSpace industry in the United States. The German TÜV were so impressed with the durability of these parts during testing that they replicated the bracket and repeated the test with a steel imitation of our part. The steel version failed early.

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

Outer rotor faces run hotter. The patent pending AeroHat™ has directional stand offs between the rotor and mounting bell (hat) that increase airflow to the outside faces of the rotor by 50-100%. Increased airflow reduces the temperature difference between the inside and outside faces of the rotor resulting in less distortion and better performance compared to other fully floating designs. Outer pad wear is reduced. AeroHat™ improves entire brake system airflow by up to 4%.

AiroHat

The below chart shows that StopTech (top red line) has the highest induced airflow of any rotor tested. Leading aftermarket and original equipment rotors were tested for airflow from 30mph to 150mph. AeroRotor® dramatically outperformed all other rotors, with improvements from an impressive 11% to a staggering 80% increase in airflow (corrected to 20°C and sea level.)

Airflow

BETTER AIRFLOW MEANS BETTER COOLING AND LESS FADE

 

STIFFER CALIPERS MEAN BETTER PERFORMANCE AND FEEL

Stoptech's ST-40 and ST-60 calipers are manufactured using a squeeze-forging process. With squeeze forging, pressure is applied during cooling. This produces a beautifully finished, solid part, without porosity. Calipers that are cast without being squeeze forged can have major issues with porosity which can even cause calipers to leak. When considering a brake upgrade, it is worth it to ask if cast calipers are squeeze forged and if not, what their testing process for finished calipers is

Stoptech does all finish machining (such as piston bores sized correctly for the application), assembly and test in California. StopTech tests every single finished caliper to 2800 psi using brake fluid on a special test bench designed by StopTech engineers.

Using finite element analysis (FEA) modeling software, we have designed a bolt-in bridge strong enough to stop distortion without sacrificing cooling through the top of the caliper. Distortion is virtually eliminated. The squeeze forged StopTech ST-40 caliper has the least flex of any tested aftermarket and OE caliper. The air channel in the bridge is designed to help air flow through the retainer, resulting in better cooling.

Caliper Stiffness

Benefits of Stiffer Calipers:

  • Better performance with less vibration, noise and pad taper
  • Better pedal feel under extreme braking conditions
  • No radial pad taper

Caliper Deflection

The chart below shows the results of testing 25 leading caliper models by the major caliper companies. Each caliper was subjected to the same pressures and deflection was measured with a dial caliper. StopTech's is the stiffest caliper of the major brands tested.

ST-40 & ST-45 - 4 PISTON CALIPER FOR FRONT & REAR

(4 piston kits with 380mm rotors use ST-45 calipers)

 

ST-40 - 4 Piston Caliper
  • Made of Squeeze Forged* aluminum alloy
  • ALL finished parts are 100% leak down and pressure tested to 2500 PSI
  • ST-40 uses standard FMSI D372 pad
  • ST-45 uses standard FMSI D609 pad
  • Any combination of 8 piston sizes available to match kit to vehicle application
  • Differential piston sizes minimize pad taper
  • Dust boots are standard
  • Weight: 7.94 lb (3.6 kg) unloaded
  • Same caliper used by top Speed® World Challenge and Grand-Am Cup Teams

* Squeeze Forged means that pressure is applied during cooling. This produces a beautifully finished, solid part without porosity.

 

ST-60 - 6 PISTON CALIPER FOR FRONT

  • Made of Squeeze Forged* aluminum alloy
  • Patented, bolt-in bridge minimizes caliper compliance for a firmer pedal
  • Stiffest 6 Piston caliper currently on the market
  • Uses standard FMSI D1247 pad
  • Can be used on rotors with outer diameter of 328-380mm and thickness of 28-35mm
  • ALL finished parts are 100% leak down and pressure tested to 2500 PSI
  • Uses a popular pad shape readily available in over 15 street performance and race friction compounds
  • Over 19 different piston size combinations available to tune brake torque to the needs of each individual application
  • Differential piston sizes minimize pad taper for longer pad life and a firmer pedal
  • Dust boots are standard for reduced maintenance

* Squeeze Forged means that pressure is applied during cooling. This produces a beautifully finished, solid part, without porosity.

 

ST-22 - 2 PISTON CALIPER FOR REAR KITS

  • Made of billet aluminum
  • All finished parts are 100% tested to a pressure of 2500 PSI
  • Uses standard FMSI D961 Pad (VIEW PAD SHAPE)
  • 2 piston opposed design
  • May be added to cars with existing front StopTech kits
  • Piston size adjusted for the application, just like our front calipers
  • Dust boots are standard
  • Weight: 4.4 lb (2 kg) unloaded
