D154 Front Caliper Kits
Wilwood's D154 Front Caliper Kit is a direct bolt-on 1 or 2 piston, lightweight, high-strength, extreme duty alternative to the OE cast iron "Metric" calipers that were used on a wide range of factory disc brake equipped mid size GM cars and small trucks beginning in 1978. Use of this caliper can still be found on some GM models as late as the year 2002. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put an end to the rust, bore pitting, and seal failures that plague the OE caliper design. D154 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D154 calipers mount in the stock location over stock rotors; use the original style OE D154 brake pads and an OE M10-1.5 banjo bolt brake line mounting. D154 Calipers can be used with most wheels that clear the OE calipers. The front calipers with 2.50” piston provide 4.90 square inches of piston area per caliper, in order to maintain the original front to rear brake bias and use of the OE master cylinder. The D154 is also available in a two piston version with 1.62 pistons, offering 4.12 square inches of area. Kits contain Wilwood’s hardened slide pins and BP-10 high friction pads. Matching rear calipers are also available for custom installations. Custom stainless steel brake lines are also available.

D52 Front Caliper Kits
Wilwood's D52 Front Caliper Kit is a direct bolt-on 2 piston replacement for the factory original single calipers on many 1968-96 GM Passenger Vehicles and Trucks. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put an end to the rust, bore pitting, and seal failures that plague the OE caliper design. D52 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D52 calipers mount in the stock location over stock rotors, use the original style OE D52 brake pads and an OE 7/16-20 banjo bolt brake line mounting. Calipers can be used with most wheels that clear the OE calipers. The front calipers with 2.00” piston provide 6.28 square inches of piston area per caliper, in order to maintain the original front to rear brake bias and use of the OE master cylinder. Kits contain Wilwood’s hardened slide pins and BP-10 high friction pads. Matching rear calipers are also available for custom installations. Vehicles 1978 & Up (with M10-1.5 banjo bolts) will require new brake lines available below.

D154 Rear Caliper Kits
Wilwood's D154 Rear Caliper Kit offers a matching rear replacement option for our front D154 calipers. It is a direct bolt-on 2-piston replacement for the factory original single piston "Metric" calipers used on many custom application rears. With the added benefit of smaller rear piston sizing (1.96 sq-inches of area) not normally available in OEM calipers, for correct front and rear bias. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put an end to the rust, bore pitting, and seal failures that plague the OE caliper design. D154 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D52 calipers mount in the stock location over stock rotors; use the original style OE D154 brake pads and an OE M10-1.5 banjo bolt brake line mounting. Calipers can be used with most wheels that clear the OE calipers. Kits contain Wilwood’s hardened slide pins and BP-10 high friction pads.

Forged Dynalite Dynamic Rear Drag Brake Kit
Dynamic rotor mounting is especially beneficial to cars that rely heavily on the rear brakes for stopping, and any other high speed, heavy weight cars that generate above average rear brake heat. Dynamic mounting uses floating t-nuts to isolate the different thermal expansion rates between the steel rotor plate and the aluminum rotor hat. This reduces any tendency for the rotor to distort and impose any additional stress on the hat. Performance, durability, and the service life of the components are all extended. Additionally, distortion free parts run with lower rolling resistance to produce higher speeds.

Dual caliper kits provide the highest degree of safety, reliability, and unsurpassed stopping power for sportsman category dragsters and other cars that rely on rear brakes only for stopping power. With two calipers at each wheel, the fluid circuits for each caliper pair can be fully isolated with dual mount or tandem outlet master cylinders. Isolating the fluid circuits prevents complete system failures in the case of a problem with any single caliper or line. Dynamic rotor mounting eliminates distortion caused by the different thermal expansion rates between the steel rotor plate and the aluminum hat.

Kits in this competition group are configured for use in production category road racing that allow brake upgrades, but limit modifications to four-piston calipers and 12.20” rotors. BSL4R/ST calipers use Thermlock pistons to resist fade and extend service life by reducing the heat transfer into the caliper from the pads. GT series directional vane rotors provide high cooling efficiency and durability mounted to the hubs with forged aluminum GT hats. Kits also include high temperature race compound pads, stainless steel flexlines, and premium grade hardware for installation in 16” and larger wheels.

BSL4R caliper rear road race kits provide matched performance in conjunction with SL6R and W6AR front race kits on vehicles built specifically for competition. BSL4R calipers use stainless steel pistons to retard heat transfer from the pads and high temperature seals for reliability in sustained high heat. Radial mount brackets attach the caliper in the stock location. GT series directional vane competition rotors provide high efficiency cooling and mount to the drive axles with forged aluminum hats. Kits also include high temperature, high friction race compound pads and all premium grade fasteners.

GP320 Midget Front Brake Kit
The GP320 System features Wilwood’s competition proven dynamic rotor mount system, specially treated PolyMetallic lightweight steel alloy rotors, and the highly efficient clamping force of the GP320 billet caliper for the most positive and fade-free performance available for sprint racing.Component Features: GP 320 Billet Aluminum 4 Piston Calipers with Four small pistons provide balanced distribution of the pad load for improved response and longer pad wear. PolyMetallic Steel Alloy Rotors: Unlike ceramic coatings that can flake away from the base metal during high heat cycling, Wilwood’s PolyMetallic coating controls heat transfer and provides a durable surface that can generate high friction for long, trouble-free duty cycles without the need for recoating. Dynamic mounting with Wilwood’s t-nut system isolates all thermal stress and distortion at the rotor mounting points caused by the different temperatures and expansion rates between the lightweight alloy steel rotor and the aluminum rotor mount plate. The rotors stay flatter and run truer to eliminate any possibility of pad knock-back or deflection. Dynamic Mount Rotor Plate: Lightweight billet alloy plate is machined with the slots to accept the rotor bolt t-nuts and adapt the rotor directly to 3 bolt sprint hubs. Wilwood 6211-CM Brake Pads A rigid caliper mounting bracket with premium grade fasteners and shim washers are included for secure, deflection free mounting.

GNX4 Front Brake Kit
GNX4 caliper Brake Kits are the product of Wilwood’s in-house FEA design and 3-D modeling technology. Paired with 12.00" diameter, .95" width rotors offers a duarble, high torque braking solution for AM General Military HUMVEE vehicles. The GNX4 Caliper With its unyielding strength and superior piston design, generates positive pedal response and high clamping efficiency with a substantial weight savings over original Calipers. The caliper feature a natural aluminum finish protected by a durable clear coat anodizing. Forged billet aluminum bodies, stainless steel pistons, and high-temperature seals put an end to the rust, bore pitting, and seal failures that plague many OE caliper design. Stainless steel pistons delay the heat transfer from the pads while the aluminum calipers dissipate the heat quicker than the OE cast iron calipers. Cooler operating temperatures translate into longer service life, regardless of the driving environment.
