Wilwood Art Morrison Multilink IRS Rear Kit, Red Superlite Calipers and GT-Slotted Rotors for the Specified Camaro-Based Configuration

Slotted 14-inch GT rotors and red Superlite 4R calipers form this rear brake package for the specified Art Morrison Multilink IRS. The service brakes mount through the documented hats and brackets while the existing suspension and parking arrangement must remain compatible. Wilwood Engineering has designed and manufactured disc brake systems and components since Bill Wood founded the company in 1977. From its Camarillo, California base, it supplies motorsport, street-performance and specialized applications with calipers, brake rotors, master cylinders, valves, fittings and brake lines. Selecting those components requires a match to the complete system.

Fitment & Compatibility

Verify the Morrison suspension identification and the actual Camaro-based hub/upright hardware before ordering. Allow for the backing-plate/dust-shield and caliper-clearance modifications in DS1046. Hoses are not supplied, and full wheel clearance must be checked independently.

DS1046 specifies trimming the backing plate/dust shield to 13.75 inches diameter and relieving the caliper mounting area; the brake-line bracket hole also needs the illustrated clearance. Follow the complete procedure before assembly.
