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 Brake Modulation
- Firmer Brake Pedal
- Less Brake Fade
Feature Benefit Summary:
- Balanced Brake Upgrades™ with optimum brake bias offer
the shortest stopping distance with the best pedal feel
- Our patented AeroRotors® with the best airflow available result in
better cooling, less fade and longer rotor and pad life
- The stiffest aftermarket calipers with patented bridge result in better
clamping under hard braking and less pad taper
- Track testing of new applications ensures optimum performance
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

What’s included?
- Calipers
- 2 piece floating directional AeroRotors with hats (pre-assembled)
- Stainless steel brake lines
- Caliper mounting brackets
- Street performance pads
Caliper Color Options
Calipers are available in the following colors:
|
Blue, gold and yellow calipers have a
30-45 day lead time and are $200 extra per axle.
|
Rotors
Rotors are available slotted, drilled or plain. Drilled rotors
are $100 extra per axle.
StopTech now offers an anti-corrosion gold zinc
coating for all AeroRotors. The coating benefits customers who live in cold
climates where snow and road salt are commonly encountered, and customers who
would prefer to not have visible surface rust on the vanes and outer
circumference of their rotors. Zinc coating does not have a negative
environmental impact like other coatings. Gold zinc coating costs $70 per axle
extra.
