The Superior 54 Sport Wagon chassis is equipped with modern, high-performance, C5 Corvette suspension that not even the renowned auto-innovator Harley Earl could have imagined. Designed and built in partnership with Art Morrison Enterprises, Inc., the chassis brings today's sports car technology to this classic.

An Art Morrison perimeter frame built to our specifications serves as the sturdy and capable foundation for this sports car. We use low-mileage, original equipment 1997 – 2004 Corvette suspension components as the basis for the Superior 54 chassis. We add Art Morrison’s front cross member, steering arm, sway bar, and power rack and pinion steering to the stock Corvette control arms, spindles, and brakes. Hi-performance coil over shocks replace the stock leaf spring. The independent rear-end and transaxle are bolted to the frame using a narrowed stock cradle, with the half-shafts and leaf spring narrowed accordingly. 

Your Complete Rolling Package will be delivered with the Body and Chassis fully assembled—ready for you to add paint, interior, engine, wiring and other personal touches to create the Retro, Custom, or Pro-Touring look you want.

Corvette C5 IFS and brakes. Alden coil-over shocks replace the original leaf spring. The Chevy LS-V8 motor mounts are provided and installed. These custom motor mounts are insulated at the frame with urethane bushings. We have this design in hundreds of high-performance chassis over the years for everything from mild-small blocks up to blown big-blocks. Complete Rolling Chassis. Includes Corvette C5 front and rear suspension, transaxle (6-speed shown), brakes lines, torque tube and driveshaft. Wheels, tires, and engine not included. Rear-view of the IRS. Note how the cradle that holds this whole unit is secured into the frame exactly as done on the Corvette. Provides for a strong, flex-free rear-end. Sway bar enhances handling. Beefy front crossmember with the power rack and pinion steering attached. Using the torque-tube from the shorter-wheelbase C5 required we stretch it and the driveshaft. The brake lines and exhaust will route through under the center stiffening plate, but not hang below the frame rails. Close up shot of the Corvette IRS. All of the original components and geometry are maintained. Narrowed half-shaft in the C5 rear suspension
