Product details
This red-caliper Evolution package uses GT slotted rotor faces with 72 curved cooling vanes. Its 14-inch front assembly retains the factory hubs, so wheel barrel and spoke clearance must be checked around the complete caliper-and-rotor envelope. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California. It designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications, with calipers, brake rotors, master cylinders, valves, fittings and brake lines in its range. Each part must be selected to work with the complete brake system and its requirements.

Fitment & Compatibility
For the 2003–2006 Evolution VIII/IX models and MR/RS applications identified in the table below. This 14-inch front package retains the original hub and uses an aluminum hat with a 0.210-inch offset. Verify the larger rotor envelope against the DS-554 wheel-clearance diagram before purchase. The stock master cylinder can be used subject to a complete brake-bias evaluation; it is not supplied. Hydraulic connections require the separately sold 220-9287 hose kit, with length and clearance checked on the vehicle. Nominal minimum wheel diameter: 18 in; 457.2 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
