Centric Parts®, North America’s leading manufacturer and supplier of aftermarket brake and chassis components, has introduced front and rear StopTech® Big Brake Kits for the 2015 Subaru WRX with stiffer calipers, larger rotors, higher friction pads, stainless steel lines and application-specific mounting brackets and hardware. StopTech High Performance Big Brake Kits (BBK) offer significantly improved braking performance, feel and modulation over stock systems and are available in a variety of caliper color/rotor finish options.
In extensive track testing with professional drivers, the front-only and 4-wheel StopTech BBKs for the Subaru WRX ran significantly cooler than the stock components. Drivers experienced less fade, better pedal feel and easier modulation. They also noted improved handling and steering thanks to front brake components that weigh approximately 9 pounds less per corner than stock.

- StopTech Street Performance Brake Pads – Kevlar®-like, para-aramid composite pads for aggressive street driving and occasional track day or autocross use.
- StopTech Stainless Steel Brake Lines – braided stainless steel shielded Teflon®-like lines for less system compliance and greater durability.
