Fitment & Compatibility
The table below identifies the applicable Evolution VIII/IX models for 2003–2006, including MR and RS versions. The iron rotor hats retain the original internal parking-brake mechanism; this kit does not supply a replacement shoe-and-cable assembly. Its specified rotor diameter is 12.88 inches. Check the original hubs, studs and parking hardware and compare the DS-558 clearance diagram to the wheels. Rear hydraulic hoses are separate; 220-9288 is the Wilwood application reference. Nominal minimum wheel diameter: 17 in; 431.8 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
