Triton Big Brake Kit - Rear
This kit, developed specifically for the E89 Z4, is the top Big Brake Kit option for your money! Sparta Evolution takes the time to focus on each make and model individually to develop brake kits that account for things such as brake bias and braking pressure to work seamlessly with the vehicle's stock ABS and traction control systems.
This Triton BBK has been designed to maximize your braking potential on both the track and on the street. Assembled with S-Grooved 2-piece rotors and Forged Triton Calipers, stopping power is significantly increased, but not so overwhelming that all daily driving functionality is gone. Offering the perfect balance of sport and race, it is easy to see why the Triton series big brake kits are one of the top picks in the market.
This Triton kit includes a number of specifically paired components including:
- Triton Forged 4-Piston Calipers
- Pegasus S-Groove 2-Piece Rotors
- Sparta Evolution Brake Lines
- Sparta Evolution Brake Pads
- Caliper Brackets with Mounting Hardware
- Installation Instruction Manual
- Warranty Info
The Triton calipers were designed for track use and heavy duty street use. To ensure top construction quality and reliability, the calipers are built from high quality aluminum in an extremely precise forging process. This helps save weight but ensures extremely high strength as well. These calipers feature 4 pistons for even pressure and greater clamping force that are Castellated. Castellated pistons are used to combat heat transfer between the brake pad and brake fluid by decreasing the contact surface area between the pad and pistons. A through-bolt design is also used to extend performance life and evenly distribute clamping load to reduce material fatigue.
The Pegasus S-Groove 2-Piece Rotors are the second star of this kit. These rotors have been designed and built for component longevity and predictability. The friction surface features 10 "S-slot" grooves that ensures contact with a leading edge, providing a fresh friction surface for the brake pads. The uniform S design helps to aid consistent pedal feel, even pad wear, and predictable bite in all conditions. This makes the rotor perfect for all weather conditions or in high thermal load vehicles that are prone to uneven wear.
Sparta Evolution SPP 1.0 pads significantly increase friction levels to increase initial bite performance and fade resistance over time. Along with increased initial bite performance, the high-caliber control of Sparta Evolution pads is made possible by formulating superior braking compounds. Made specifically for big brake kits, these are designed for both street and spirited use, offering low noise, similar to OE characteristics, and a low initial operating temperature but with a wide working temperature range up to 400 degrees celcius.
Every Sparta Evolution BBK includes their upgraded Stainless Steel Braided Brake lines that have been tested in all conditions to ensure they will never fail. They have been Teflon coated to guard against wear and tear and use OE measurements and OE design fittings on the vehicle side for an issue free connection. They are also DOT and TUV approved for street use.
Finally, all needed brackets and hardware for fitment and installation are included. These allow the calipers and rotors to bolt up easily to your vehicle with no more effort than a standard brake change and brake fluid bleeding.
Below you can find the wide variety coating options that make these rotors really stand out from behind your wheels. For this kit, you can choose between a Powder Coating, an Anodized Coating, or a Nickel Alloy coating. The powder coating is standard and is what is used in most modern BBKs today. For an upgrade in both performance and protection, you can choose to go with our Anodized coating or Nickel Alloy coating. These offer a much sharper look, higher temperature resistance range, better scratch resistance than powder coating, and tighter and more precise tolerances thanks to how thin the treatment applies.
This kit features 345mm rotor, a 45mm increase in diameter over the stock 300mm rotor size.
