Wilwood Disc Brakes has recently introduced new W6AR front and W4AR rear big brake upgrade kits for the 2008-2009 Pontiac G8. These track tested kits provide big brake styling and real big brake stopping power for use in conjunction with wheel and tire upgrades for street, track, or show. Both kits work harmoniously with the original equipment master cylinder and ABS functions.
Front kit (P/N 140-12929) features forged W6AR 6 piston differential bore calipers that provide enhanced performance over the original stock calipers coupled with 14.25” vented rotors. Calipers
feature six differential bore stainless steel pistons that 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. Rear kit (P/N 140-12932) comes with W4AR 4 piston symmetrical bore calipers along with 14.25” vented rotors. Base model kits include either 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.
Both kits can be purchased with either 14.25” diameter 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 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.
Friction 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 those fun days at the track. 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 (P/N 220-9248 front, 220-8755 rear), required to adapt Wilwood calipers to your chassis
plumbing is included with each kit.
All of Wilwood’s performance brake kits are loaded with cutting edge technology built on years of
domination in world motorsports, and proven reliable through Zero PPM defect supply to OEM’s.
Wilwood’s Big Brake Kits are designed to meet the high performance demands of today’s tire, wheel
and suspension technology.
