Complete Kit Weighs Approximately 39 Pounds!

The FDL Pro-Series Front Hub Disc Brake Kits offer complete disc brake upgrade solutions for traditional non-ABS spindle applications on American muscle cars, vintage rods, and heavy weight drag cars. Based on the venerable forged billet Dynalite caliper, these versatile kits are easily optioned to suit the braking requirements and style preferences for a daily driver, serious competition, or the most discriminating show enthusiast. Most kits require no modifications for installation, and provide plenty of clearance inside popular 15" wheels. FDL Pro-Series kits can be used with either manual or power boost master cylinders.

Forged Dynalite Caliper:

The Forged Billet Dynalite Caliper has wide spread application over many forms of motorsports. It serves as the base model in the majority of Wilwood's Bolt-On Disc Brake Kits. The latest applied developments and innovations in caliper design and manufacturing processes have resulted in substantial improvements in strength and performance over all comparable models.

Forged Dynalites are the strongest calipers in the class, with weights starting at 2.80 pounds. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper body. This process eliminates the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. The FEA generated radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridges. Incorporating a radius in this transition area substantially increases resistance to deflection and caliper separation under load. Structural deflection and volume displacement tests have proven the Forged Dynalite Caliper to outperform all existing styles of this popular caliper size. Without even considering the overall greater strength and reliability of the forging, the reduced deflection tendencies and the resulting decrease in fluid volume displacement translate to increased clamping efficiency with less pedal travel. The bottom line is a taller pedal and better stopping power.  

The superior strength of this innovative design is combined with proven performance features from Wilwood's earlier designs. Each caliper is equipped with Wilwood's SRS stainless steel bridge plates. The 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 seals and stainless steel pistons to eliminate corrosion and retard heat transfer from the pads. Internal fluid passages eliminate the need for external tubes. Four corner bleed screws assure simple and effective air evacuation from the system and allow one caliper to be mounted in any front, rear, right or left position. Standard race calipers feature Wilwood's signature bright black anodized finish to resist corrosion and maintain their high tech style.

Forged Dynalite calipers are a direct replacement for all Wilwood Dynalite and similar competitive brand calipers with 5.25" centered mounting lugs. The Forged Dynalite uses the same 7112 type brake pad used in all earlier versions of this caliper. 

Ultralite HP 30 Vane Rotor:

Ultra-Light ULHP straight vane rotors provide high value performance and rugged durability for a wide range of competition, high performance, and sport driving applications. Don't confuse these rotors with bargain priced off-brand named parts. Wilwood's modern manufacturing capability, combined with large scale ecoNmies, make it possible to offer this level of quality and performance at such an affordable price. 

Every Wilwood rotor is cast from premium grade, long grain carbon iron. This material exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 30 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting locations.   

ULHP series rotors provide the additional performance and smoother operation of precision machined faces with less than .001" variation in flatness, parallelism, and run-out.

DynaPro 6 forged billet calipers are combined with 12.19" diameter rotors for this group of traditional non-ABS spindles on American muscle cars and vintage rods. The enhanced brake capacity and pad performance of the six piston calipers provide an intermediate level alternative to the bigger six piston kits. These kits compliment wheel, tire, and suspension upgrades on all types of custom show and high performance street / strip machines.

Dynapro Six Piston Lug Mount Calipers:

The DP6 marks a noteworthy step in the evolution of the DynaPro caliper series. DP6 calipers offer the performance advantages of a larger pad and a six piston differential bore configuration, with complete bolt-on interchange ability to the four piston 5.25" lug mount DynaPro models, and the long standing Dynalite caliper series.

As with the previous DynaPro models, the strength of the DP6 is a combination of process and design. Premium grade alloy billets are stress-flow forged resulting in a highly efficient, high strength body. Stress flow forging re-aligns the internal grain structure of the metal within the contour of the caliper body. This process is proven to provide superior strength over any other process derived from castings or straight billet block machining. FEA assisted solid modeling design technology was employed to find the optimum balance between lightweight with superior strength against deflection and body separation under high load.

In addition to the sturdy, yet stylish body, the DP6 incorporates race proven technology and the latest Wilwood performance enhancements. Pad clamping force is generated by six heavy wall stainless pistons configured in a leading to trailing edge differential bore pattern. The heavy wall pistons have been re-engineered to fully resist backside deflection at high pressures while maintaining balanced pad loading for even wear over the length of the pad. Stainless steel resists corrosion while inhibiting direct heat transfer from the pads to caliper body, seals, and fluid. Two choices for overall piston volume provide options to match caliper size with master cylinder output and bias requirements.

The DP6 uses the upgraded type 6712 pad that provide the larger overall volume size from the previous Dynalite and DynaPro four-piston models. The pads are retaining with exclusive Wilwood Quick-E clips for simplified pad service and maintenance without caliper removal. Stainless steel SRS bridge plates are used to dampen engagement harmonics, eliminate pad rattle, and protect the caliper bridges from gouging by the pad edges. Four corner bleeds and internal fluid passages accommodate front or rear mounting and simplified gas evacuation regardless of mounting position.

SL6R forged billet six-piston calipers with 12.88" rotors deliver the ultimate combination for braking power and style in this group of kits engineered for traditional non-ABS spindles on American muscle cars and vintage rods. Built exclusively for 17" and larger wheels, SL6 kits enhance tire and suspension upgrades on all types of custom show and high performance dual-purpose street and track machines. A full range of options for caliper finishes and rotor designs are guaranteed to catch the eye of the most discriminating enthusiast while providing optimized brake performance for every individual application.

Billet Narrow Superlite 6 Radial Mount Calipers:

The billet SL6R series adds the versatility and convenience of radial mounting to this widely popular caliper group. Radial mounting simplifies adaptation and provides two planes of adjustment for accurate alignment over the disc. These calipers integrate "Big Brake" style with Wilwood's latest technology to generate big stopping power in extreme environments over a broad range of vehicle applications.

The key to the superior performance of the SL6R comes from the extremely durable and efficient body design. Starting at 4.84 pounds it is the product of computer generated solid modeling and FEA stress analysis technology. Full length stiffening ribs and a reinforced radial transition from the piston bore housings to the closed end bridges has produced the strongest SL caliper bodies ever built. When compared to open bridge calipers that use tube or stand spacers between the body halves, the closed end bridge design is measurably stronger with less separation or deflection under load. Additional strength and resistance to deflection comes from the four high-strength steel end bridge bolts. A fifth center bridge bolt provides even more overall strength and easy access to the pads without the need to remove the caliper from the mount.

A unique six-piston differential bore configuration provides balanced loading for even pad wear in sustained high heat environments. The standard SL6R calipers feature one-piece stainless steel pistons. Stainless is used for its slow heat transfer properties and high resistance to corrosion. The SL6R/ST models feature Wilwood's exclusive Thermlock pistons. This multi-part piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to caliper body, seals, and fluid. Cooler temperatures translate to longer service life and less chance for heat induced pedal fade.

In addition, each SL6R is equipped with SRS bridge plates. SRS plates eliminate all bridge wear caused by pad gouging and extend the service life of the caliper. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens the harmonic vibrations that contribute to pad squeal. Two piece bleed screws and dampened fluid tubes are recess mounted to shield them from track debris and other potential damage sources. High temperature, square faced bore seals provide the largest possible sealing area and controlled piston retraction on release. The full range of Wilwood pad compounds is available to match the brake response and heat range of any competition or sports driving application.

Calipers in this group feature a reduced width outboard body to provide additional clearance between the caliper face and the wheel or hub. These calipers were originally built for use with wide 5 hubs, but have found their way to OE performance "Big Brake" conversions, road racing, and other close fit wheel applications. The caliper bridge radius will clear rotors from 11.75" to 13.00" in overall diameter. Each caliper in this group uses 7420 type 20mm thick pads.

GT 48 Curved Vane Rotors:

GT-48 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.
