Subaru WRX 2007, Dynapro Radial Mount 4-Pistons Red Powder Coated Front Caliper (120-7378-RD) by Wilwood®. Mount Type: Radial, Piston Material: Aluminum, Piston Area: 4.12 sq.in. DynaPro four piston radial mount calipers combine pure race technology with a new generation of Wilwood performance enhancements. The DynaPro combines the versatility of radial mounting with a sleek profile, superior strength, and extreme durability in adverse conditions. With an overall weight as light as 3.58 pounds, the DynaPro has become a favored choice for a broad range of sports, rally, and off-road driving applications.
Fits Following Models:
- Subaru WRX With 310mm (12.19") Rotor With 0.81" Wide Rotor
- Subaru WRX Limited Wagon
- Four corner bleed screws allow the caliper to be mounted in any front, rear, right, or left position
- Fits rotors from 10.00” to 13.00” in diameter, and widths from .38” to 1.25”
- Utilizes a 3.00 cubic inch type 7816 pad available in many Wilwood compounds
flow within the contour of the caliper body. This produces a part with superior strength over machined block billet parts or castings. The FEA generated body design features a radial transition between the piston bores and caliper bridges. This eliminates macined steps and shoulders in this critical strength area and substantially increases the resistance against deflection and body separation under high load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. The bottom line is a firm pedal with outstanding stopping power.
The DynaPro is available in four configurations. Standard calipers for rotors up to 12.19” feature dust-booted aluminum pistons for maximum protection against track or road born debris in low to intermediate temperature applications. A long radius version is available to accommodate rotors up to 13.00”. Competition models use heavy wall stainless pistons to provide addition protection against corrosion and heat transfer from the pads. All DyanPro calipers can also be optioned with Thermlock pistons for maximum thermal protection in sustained high-heat applications. Optional side inlet calipers are available to simplify plumbing with inboard mounted brakes on live axles and independent suspension rears.
DynaPro calipers use type 7816 pads that are supported from the top by Quick-Clip pad retainers. Quick-Clips allow fast access to the pads for service without the need to dismount the caliper. The Quick-Clip design also allows additional inside radial clearance between the caliper body and the lug hub by eliminating the bottom pad support feet found on other caliper models. Side inlet DynaPros use additionally fortified bridge bolts in place of the Quick-Clips for the ultimate in secure pad retention within high load environments on sprint cars and other extreme duty applications.305.50Brand: Wilwood Part Number: 120-7378-RD
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since founding in 1977, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Their core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
