Includes
- 6-piston billet-aluminum calipers
- Floating 2-piece discs with weight-saving aluminum hats
- Braided stainless steel brake lines
- Billet-aluminum mounting brackets
- High-performance street pads
- All necessary install hardware
Features
APR® MTR system provides a permanent record of peak operating temperatures reached by the discs under actual driving
All discs are coated with a proprietary black surface coating
APR® calipers use high-tensile caliper cross-bolts that are manufactured in Europe. The bolts greatly increase caliper rigidity while adding minimal weight
The seamless fluid crossover tubes are manufactured from CuNi alloy. This material handles high-frequency vibrations vastly better than coated or stainless steel tubs as are commonly used in the industry
All caliper component hardware, other than the cross-bolts, are manufactured from stainless steel
APR Calipers have an internal wiper seal in the caliper body and around the pistons to protect the pressure seal from possible external debris
This system provide a permanent record of the maximum operating temperature reached by the caliper
Race proven over many years of use, the floating system allows the disc friction ring to expand and contract radially without any restrictions as it heats and cools
Product Details
Slotted Big Brake Kit by APR®. APR’s Big Brake Upgrade is an ultra-durable, feature-packed solution specifically tailored to each vehicle. The brakes provide outstanding stopping-power at an affordable price and are targeted towards a wide operating range such as normal or spirited street driving, track days and HPDE events. The system handily out-brakes, out-lasts, and out-performs other systems on the market, including much larger and heavier setups such as the factory standard RS3/TTRS brakes!
Installation
Benefits:
- Larger diameter and wider discs add significant thermal capacity to the brake system
- Advanced, directional cooling vanes get rid of heat far more efficiently
- 2-piece discs allow disc friction rings to expand & contract independent of the disc hats, hereby greatly reducing stresses and "coning effect" of the discs at high operating temperatures
- Although the 2-piece discs in big brake kits are larger, they often weigh significantly less that the factory 1-piece discs as a result of the lightweight, billet hats. This reduces un-sprung weight, rotational mass and gyroscopic effect
- Lower operating temperatures increase disc life significantly
- Larger pad volume increases pad life significantly
- Compliance or "flex" is greatly reduced throughout the system resulting in a firmer brake pedal and improved brake modulation
- Stainless steel braided brake lines have far lower volumetric expansion that factory rubber brake hoses
- Billet multi-piston calipers are significantly more rigid than factory calipers
