The ultimate in brake technology for your vehicle



The Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade designed to enhance brake power under sustained high-heat conditions. All calipers feature 1-piece construction from a solid billet of aircraft grade aluminum for lightweight, unparalleled strength and freedom from corrosion. Calipers also feature aluminum pistons that provide better heat resistance and uncompromised operation. The Procomp Big Brake system is designed for easy installation with minimal tools required in most applications.


Our most extreme brake upgrade, the Supercomp Big Brake Kit is designed to provide the highest level of stopping power without requiring any vehicle modifications to install. This sophisticated bolt-on brake upgrade features the same benefits of our Procomp kit but features larger calipers, rotors, and brake pads, as well as increased pistons and standard full-floating rotors for better self-centering in the caliper. 



Designed with Drifting and Rally Racing in mind, the all new Ksport Dualcomp Big Brake Kit is the ultimate all-in-one Dual Caliper solution. This system utilizes a single 4 Pot caliper, with 2 Pots used for the foot brake and 2 Pots used for the handbrake – each runs independent from the other on its own system. For those looking for a brake kit that has been tested and proven to perform on Rally Racing or Drift Circuits, the Dualcomp Big Brake Kit is the ultimate choice. 

*This kit is Formula Drift legal


The popularity of aggressive fitting wheels on factory body vehicles has never been more popular than it is today. In most cases, aftermarket big brake kits aren’t compatible with this style. Large multi-piston brake calipers just don’t fit within the very limited spacing between the larger brake caliper and the back of the wheel. Ksport has developed the Slimline Caliper with this issue in mind, a design that’s based on the OEM single-side floating piston caliper thickness.
