General Benefits of Big Brake Kits

Big Brake Kits give your vehicle that Supercar look and feel, and exceed stock performance in two areas. First, larger rotors increase heat capacity. Second, stiffer calipers and stainless steel lines reduce system compliance.
 

The key, however, is to increase heat capacity and reduce compliance without upsetting the stock front to rear brake torque ratio. If the brake upgrade you select adds too much front torque (as many do), you reduce your car's ability to utilize the tractive capacity of all of the tires to the maximum practical extent (even on ABS equipped cars) and you therefore create performance sacrifices. In addition, too many pistons or pistons that are too large will make the brake pedal much more difficult to modulate, which limits a driver's control of brake input on the race track.

Advantages of StopTech over other brake upgrades:

• Shorter Stopping Distances

• Better Looks

Feature Benefit Summary:

• Balanced Brake Upgrades™ with optimum brake bias offer the shortest stopping distance with the best pedal feel

ST-40 & ST-45 - 4 PISTON CALIPER FOR FRONT & REAR (4 piston kits with 380mm rotors use ST-45 calipers) 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 (VIEW PAD SHAPE) ST-45 uses standard FMSI D609 pad (VIEW PAD SHAPE) 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 (VIEW PAD SHAPE) 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

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
