2008+ Dodge Challenger - All Models
The Challenger engineers developed a vehicle, which was released to the public in 2008 with tremendous fanfair and popularity, that is an absolute monster. The Previous generation Challenger hadn't been produced in years, so Dodge went back to the drawing board and released a gorgeous and powerful vehicle that has been turning heads since it hit the market. Three models of the Challenger were released. The SE V6 Challenger, while underpowered compared to its other model brethren, is still a beast of a vehicle with a powerful and capable engine that could benefit from increased stopping power, since it has the ability to get to speed so easily. The Hemi R/T and SRT-8 Challenger models, on the other hand, are anything but underpowered. Those high HP monster machines can really get moving, and high performance brakes from Wilwood are the perfect complimentary accessory to bring the big beast to a stop quickly and smoothly. These Wilwood Big Brake kits come in various different applications to match the performance style needs of your Challenger, and being that they're Wilwood, you can be absolutely certain that you are getting the very best for your dollar. Wilwood has been tearing up the performance brake scene for some time now, and the reviews for their products are universally outstanding.
Billet Superlite 4R four piston calipers are combined with BP-10 compound pads and 13”-14” rotors in this group of big brake kits for custom high performance street and show machines. This group of specialized kits for cars, trucks, and SUV’s retain full use of the OE parking brake, master cylinder output, and ABS where used. SL4R rear kits provide complimentary style and performance with 13” and larger front brake upgrades in conjunction with wheel, tire, and suspension upgrades. Optional caliper finishes and rotor designs enable the builder to match style and performance on all applications.
Calipers
Billet Narrow Superlite 4
The Superlite caliper series has set the standard for many years in short track, late model, modified and open wheel competition. It has also enjoyed prominence in a variety of road-race, off-road, rally and sport driving applications. Starting at 4.40 pounds, the Forged Billet Superlite (FSL) is the newest innovation to this series from Wilwood. New and adaptive technologies have been applied providing substantial improvements in strength, fluid volume displacement, and overall performance.
The Superlite caliper series has set the standard for many years in short track, late model, modified and open wheel competition. It has also enjoyed prominence in a variety of road-race, off-road, rally and sport driving applications. Starting at 4.40 pounds, the Forged Billet Superlite (FSL) is the newest innovation to this series from Wilwood. New and adaptive technologies have been applied providing substantial improvements in strength, fluid volume displacement, and overall performance.
The FSL body design is a highly efficient product of computer generated solid modeling and stress analysis technology. Each caliper features closed end bridges with a radial transition to the piston body housings. The elimination of machined steps and sharp shoulders in this critical area provides a measurable increase in overall body strength and resistance to deflection under load. Center bridge bolts replace cotter pins to provide additional support and allow quick access with positive brake pad retention. Clamping force, structural deflection, and volume displacement tests have proven the superior strength and efficiency of the FSL. On-track testing has proven driver satisfaction. The bottom line is better stopping power with less pedal travel.
The superior strength of this innovative new caliper is combined with proven performance features from other Wilwood designs. Each caliper is equipped with Wilwood's replaceable SRS stainless steel bridge plates. SRS plates eliminate the bridge wear caused by pad gouging and extend the service life of the caliper body. The spring-loading action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to squeal under braking. Other standard Wilwood features include high-temperature, square faced o-ring seals for positive sealing, controlled piston retraction, and long service life in high heat conditions. Stainless steel pistons are used to resist corrosion and retard heat transfer from the pads. Fluid tubes are vibration dampened to resist stress fractures and reduce damage caused by track debris. Two-piece bleed screw assemblies provide long, reliable service life and are easily replaced if necessary.
Forged Billet Superlite calipers are a direct replacement for all Wilwood Superlite and similar competitive brand calipers with 3.50" centered mounting tabs. Calipers are available in the popular 1.75", 1.62”, 1.38", 1.25” and 1.12” piston sizes for .81", 1.10" and 1.25" rotor widths. FSL calipers use the same 7420 type bridge bolt brake pad used in all Superlite 6 piston calipers. The full range of PolyMatrix pad compounds is available to match brake response and heat range to any application.
Rotors
GT-72 curved vane rotors are built for the extreme conditions of professional motorsports. The superior heat absorption and dissipation characteristics of these heavy wall directional vane rotors are the keys to preventing heat fade and realizing long service life from the rotors and pads. All rotors are cast from premium grade, long grain carbon iron for long wear, thermal stability, and resistance to distortion. Every GT rotor is fully detail machined to eliminate stress points and unnecessary weight away from the pad sweep face. The faces and O.D. are precision turned to less than .001" for flatness, parallelism, and run-out. An asymmetrical face slot pattern provides smoother engagement through reduced harmonics and improved thermal balance between the I.D. and O.D. of the rotor. Every rotor is then individually dynamic balanced to provide vibration free performance at any speed. These rotors provide the highest cooling capacity and longest service life for extreme braking short tracks and road course competition.
Rotor Hats
Parking Brake Hat - Standard
These premium grade cast iron hats are used with Wilwood's internal shoe parking brake kits. Each hat is a precision machined, threaded hole design for use in conjunction with through-hole mount rotors. After machining, the hats are electro-coated for corrosion resistance.
