RS Performance Concepts

In order to meet the demand for growing modified performance muscle cars, the Roadster Shop has opened a new division, RS Performance Concepts, to deal strictly with the muscle car market.  Our goal is to provide high quality, high performance chassis and turn key builds for the 60's and 70's era cars. 

Introducing the RS Performance

1964-72 Chevelle Chassis

True Fit, True Performance

Out with the old and in with the new.  The RS performance chassis has been designed for extreme strength, performance, and handeling with all of the desired features combined into one package for the ultimate pro-touring Chevelle build.  Great steps have been taken to build the ultimate performance chassis.  The chassis is designed to be a direct bolt up to your original body requiring no mmodifications.  The chassis retains all stock bumper, core support, and body mounting points.  Ride height is also lowered by approximately 3" - 4".
