Product Description

Benefits of Big Brake Kits

Big Brake Kits give your vehicle that Supercar look and feel, and exceed stock performance thanks to larger rotors which increase heat capacity and stiffer calipers and stainless steel lines that reduce system compliance.

The key, however, is to increase heat capacity and reduce compliance without upsetting the stock front to rear brake torque ratios. 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
  • StopTech's 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

What's included?

  • Calipers: ST-40 (4 Piston), ST-60 (6 Piston)
  • 2 piece floating directional AeroRotors with hats (pre-assembled)
  • Stainless steel brake lines
  • Caliper mounting brackets
  • Street performance pads

Caliper Color Options

Note: Silver, Yellow, Blue and Gold calipers have up to a 30 day lead time. Yellow, Blue and Gold are $200 extra per axle. No extra charge for Red, Black and Silver.


Rotors are available in slotted or drilled and with/without gold zinc coating. Drilled rotors are $100 extra per axle. Gold zinc coating are $70 extra per axle.

The anti-corrosion gold zinc 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.

Brake Pads

The calipers in this kit comes with Axxis Ultimate performance brake pads. The performance pads included with kits are suitable for both street and light track use such as Autocross (1 lap at a time). For more aggressive track use or race use, it is very important to select pads appropriate to the type of driving. If you wish to order alternative pads separately please contact us.

Caliper Clearance

Most 17' wheels will clear the outer diameter of the caliper for a 332mm kit. For a 355mm kit, a minimum 18' wheel is typically required. The more critical clearance, however, is the gap between the spokes of the wheel and the face of the caliper. Do not assume that a larger-diameter wheel will automatically clear the face of the caliper. StopTech recommends at least 2mm of additional clearance. See the Wheel Fitment Drawing page on the StopTech website for more specific measurements, at
Note: Final fitment of the wheel to the caliper is the responsibility of the customer.
