Racer Sideways - Group 5 1976-82


Spirit of the class

The group 5 regulations introduced in 1976 were designed to remove the restrictive prototype rules and allow manufacturers to compete at the highest level with race cars developed from production-based road cars. This resulted in an absolute glut of technically impressive cars hitting the grid.

The Racer sideways range includes a wide choice of the most successful versions raced around the globe and will be the basis of this class.
