Product details
Black six-piston Superlite calipers and 14-inch SRP rotors give this Evo front package its configuration. The drilled/slotted rings attach to aluminum hats, with separate front hoses required to connect the new calipers. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; its Camarillo, California operation serves motorsport, street-performance and specialized applications. Every component must suit the complete brake system in which it operates.

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.
