Kit Features:

Forged Billet DynaPro 4 Piston Calipers
The DynaPro four-piston radial mount caliper is a combination of process and design. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper body. This eliminates the stresses 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 critical area substantially increases resistance to deflection and caliper separation.



The DynaPro uses a new 7816 type brake pad that is supported from the top by Quick-Clip pad retainers. This eliminates the need for a pad support step in the bottom of the caliper, and adds additional clearance for mounting closer to the hub on small wheel and rotor applications. The pad radius matches rotor diameters 9.45" - 12.19", and the caliper fits easily inside many 13" wheel applications. The Quick Clips also accommodate easy pad access without caliper removal. Other features include coated aluminum pistons fitted with high temperature rubber boots that seal out dirt, moisture, and debris from the piston bores. Every caliper is equipped with Wilwood's SRS stainless steel bridge plates. The SRS plates eliminate the bridge wear caused by pad gouging. The spring-loading action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to squeal under braking. Internal fluid passages eliminate the need for external tubes. Four corner bleed screws assure simple and effective air evacuation and allow one caliper to be mounted in any front, rear, right or left position.



Note: For sustained high temperature operation in severe duty competition, the DynaPro can be fitted with one piece stainless steel or Wilwood's exclusive Thermlock ® piston technology without the dust boots.



GT Series Rotor Mounting Hats


GT aluminum hats are lightweight and strong. The hats are specially designed for use on OE hubs without modifications or interference to the suspension or ABS components. The hats carry Wilwood's signature and a black anodized finish that prevents corrosion and enhances the overall appearance of the complete package inside the wheel.



SRP or HP Series 12.19" Vented Iron Rotors


12.19" vented iron rotors add stopping power and cooling capacity over smaller diameter OE rotors. All Wilwood rotors are manufactured from premium grade, long grain carbon iron to provide long wear with high thermal stability and resistance to distortion. The superior heat absorption and dissipation qualities of a vented iron rotor are essential to preventing heat fade and realizing the longest service life from the pads and rotors. Every kit in this group includes a 12.19" diameter SRP or HP series rotor. For custom, show, and high performance sport driving, SRP rotor kits offer the high-tech look and improved performance of a directional cross-drill and face slot pattern. In addition to their aesthetic appeal, the venting and cleaning action of the holes and slots will reduce pad glaze, dissipate surface heat, and minimize irregular pad build-up on the rotor faces. The results are smoother engagement with improved consistency and response at the pedal. SRP rotors are treated with a silver zinc wash to reduce corrosion on the areas of the rotor not kept clean by pad contact. HP rotor kits include close tolerance machined smooth faced rotors. The additional mass of the HP rotor extends service life on heavier competition vehicles and severe duty applications subject to higher sustained operating temperatures.



PolyMatrix Brake Pads


PolyMatrix 7816 "Q" compound pads operate at the lowest noise and dust level of any performance pad. "Q" has fast response, high resistance to fade, long wear, and the low rotor abrasion that PolyMatrix is so well known for.



Caliper Brackets and Hardware


Aluminum mount brackets with steel threaded bolt hole inserts are lightweight and strong. Each bracket is CNC machined for precise fit on each specific spindle. Grade 8 or higher and AN style nuts, bolts, studs, washers, and alignment shims are included in all applicable kits.



Plumbing


Fittings and flexlines to install these brake systems must be ordered separately. Applicable hose kit part numbers are listed next to the kits in the ordering information.



NOTE:


Installation of Wilwood Disc Brake Kits may affect the wheel offset.
