Wilwood Disc Brakes has recently introduced two new re-engineered rear high performance disc brake kits for the Subaru WRX / Impreza that features the latest in disc brake technology. Part number 140-12877 is for model years 2008-2012 WRX, and part number 140-12878 is for model years 1999-2005 WRX, and 1999-2007 Impreza. These upgraded brake kits are designed to enhance safety and performance while providing the ultimate in race technology to compliment the front Wilwood Big Brake kits recently introduced. Kits are designed to retain full functionality of the Original Equipment (OE) internal drum shoe parking brake system. And, kits will work harmoniously with the original equipment master cylinder and ABS functions. However, they will not fit stock wheels.*
Big brake clamping power is delivered by Forged Narrow Superlite 4R (FNSL4R) radial mount four piston calipers. Four symmetrical bore stainless steel pistons provide fully balanced pad loading, along with the corrosion resistance and thermal retardant qualities of the stainless alloy that will keep your calipers cooler and running trouble free for many more miles down the road or track. For more aggressive race applications, calipers can be fitted with our exclusive Thermlock pistons which
provide the most effective thermal barrier for minimizing heat transfer from the brake pads to the caliper body, seals, and fluid. The calipers are available with either black or red high-gloss, hightemp, brake fluid resistant sealed powder coat and feature Wilwood’s signature logo.
Kits come with our proprietary Spec 37 compound in 12.88” diameter GT competition series, or SRP drilled and slotted rotors to maximize braking capacity and match style with your wheel size and design. GT rotors are fully detail machined from premium grade carbon iron castings, face slotted, and individually dynamic balanced to provide true and precise running at all speeds. SRP performance rotors feature Wilwood’s signature directional drill and slot design with a protective Ecoat finish. The drill and slot pattern adds race-tech styling and the venting qualities that preserve pad performance. The heat resistant E-coat finish protects the rotors from rust on all areas that are not swept clean by the brake pads.
Stopping power is provided by BP-10 compound Wilwood “Smart Pads”. BP-10 is a unique metallic composite formula that provides quiet engagement and low dusting, but with the added temperature range and higher friction values of a semi-metallic compound pad. BP-10 runs clean and quiet on the street, with improved stopping power and fade resistance for tough roads and lighter duty use during those fun days at the track. Optional high-temp and race only pad compounds are also available.
All of Wilwood’s performance brake kits are loaded with cutting edge technology built on decades of domination in world motorsports, and proven reliable through Zero PPM defect supply to OEM’s. These kits will not only exceed your braking demands, on and off the track, but also enhance the appearance of your Subaru.
