Wilwood Disc Brakes is proud to introduce three new re-engineered front upgrade disc brake kits for
the 1999-2012 Subaru WRX. These upgraded brake kits significantly enhance safety and
performance for street use, while exceeding the demands of track events from Autocross to the most
challenging SCCA Road Race venues. Kits are offered with Forged Narrow Superlite 6 Radial
(FNSL6R) mount, or W6A Radial mount calipers with 13.06” or 14.00” GT slotted, or SRP drilled and
slotted rotors. These kits work harmoniously with the original equipment master cylinder and ABS
functions. However, they will not fit stock wheels.*
High strength clamping force and positive stopping power are the trademark of the Wilwood net
forged FNSL6R and Aero 6 calipers. Six differential 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. Base model kits include either sealed gloss black or red
powder coat calipers. Wilwood’s new Quick-Silver series nickel plated calipers are also available as
an option by special request.
All three kits can be purchased with our proprietary Spec 37
compounds in either the GT competition series, or the SRP series drilled and slotted E-coat 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 E-coat 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.
The FNSL6R 13” (P/N 140-12874) and 14” (P/N 140-12875) kits come with BP-10 compound “Smart Pads” that provide quiet engagement and low dusting, but with the added temperature range and higher friction values of a semi-metallic compound pad. The Aero 6 14” kit (P/N 140-12876) comes with Wilwood’s extreme duty dual-purpose street/track BP-20 compound “Smart Pads”. Optional high-temp and race only pad compounds are also available.
To complete the installation, precision machined and application specific brackets come along with
premium grade hardware and alignment shims for a secure and accurate installation. DOT approved
flexline kits, required to adapt Wilwood calipers to your chassis plumbing are included with the kits.
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.
