Pro-Matrix Front Kit: 94-04 Mustang Cobra

Kit Features:



Pro-Matrix OE Brake Upgrade Kits provide the sports driving enthusiast with the benefits of Wilwood's championship race technology on their OE caliper equipped machines. Wilwood SRP or GT series directional vane rotors are matched with PolyMatrix brake pad sets and DOT approved stainless steel reinforced brake hoses. These packages provide cool running with improved overall system performance for enhanced street driving and track day competition. Each kit is application engineered as a direct bolt-on replacement with full compatibility to the OE calipers, hubs, mounting, master cylinder, and ABS systems.



SRP Series Drilled Performance Rotors


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 the aesthetic appeal, the venting and cleaning action of the hole and slot pattern on the SRP rotors will reduce pad glaze and minimize irregular pad build-up on the rotor faces. The results are smoother engagement at the pedal and improved consistency and response from the pads. Wilwood's premium long grain carbon iron castings are precision machined at less than .001" for flatness, parallelism, and run-out. All SRP drilled and slotted rotors are finished with a silver zinc wash to reduce corrosion on areas of the rotor not kept clean by pad contact.



GT Series Competition Rotors


For competition, track day events, or any type of sustained heavy-duty use, GT rotors offer the benefits derived from over 26 years of race rotor development. Wilwood's premier rotor series features technology developed for the extreme environments of professional motorsports. Highly precise castings are fully detail machined to eliminate stress points and unnecessary weight. The faces are precision machined at less than .001" for flatness, parallelism, and run-out. An asymmetrical face slot pattern provides smoother engagement through reduced harmonics and improved thermal balance. Every GT rotor is dynamically balanced for smooth performance at every speed. GT rotors will provide the longest service life in sustained high temperature environments.



GT Series Rotor Hats


These premium grade aluminum hats are lightweight and carry the strength to manage the exceptional brake torque generated by a Pro-Matrix upgrade. The hats are designed by each application for precise fit without interference or modifications to the stock components and ABS systems. Wilwood's signature appears on a high luster black anodized finish that prevents corrosion and enhances the overall appearance of the complete package inside the wheel. Always use genuine Wilwood hardware for rotor and hat mounting.



PolyMatrix Brake Pads


PolyMatrix Brake Pads for the OE front calipers provide fast response with high resistance to fade, long wear, and the low rotor abrasion that PolyMatrix is so well known for. SRP rotor kits include PolyMatrix "Q" compound pads. "Q" is a ceramic enhanced formula developed for improved stopping power, ultra-quiet engagement, and the lowest possible dusting available from a performance compound pad. "Q" provides quiet, consistent stops over a wide temperature range without all the annoying dust on the wheels. "GT" rotor kits include PolyMatrix "E" compound pads. "E" is an excellent track day and auto cross pad. It generates substantially higher friction values over a much wider temperature range. "E" does not have the higher noise level or abrasive rotor wear associated with high metallic based compounds. Both "Q" and "E" have an easy break-in period and are easily bedded with new cast iron rotors. For endurance events, club racing, and extreme duty competition, PolyMatrix "J" compound pads can be purchased separately for use with GT series rotors.



Plumbing and Hardware


The correct hardware with DOT stainless steel flexlines, and special 12 point head, lock wire drilled, stainless steel rotor bolts are included with each Pro-Matrix Kit. In addition to the added eye appeal, stainless reinforced hoses provide a firmer, more consistent, and faster responding pedal by minimizing compliance and volume loss within the system.
