Roadster Shop SPEC Chassis Kits

Roadster Shop SPEC chassis kits offer Roadster Shop quality at an affordable price point. The SPEC Series is an engineering-focused approach, using the latest in manufacturing technology, to build the lightest, strongest, and easiest-to-install complete chassis systems. These technologies have been used to streamline procedures resulting in lower cost and shorter lead times.

The SPEC independent front suspension is engineered to deliver outstanding performance in a user friendly package. It features proprietary suspension geometry designed to provide the best balance of ride quality and performance in its class.

Available as On-The-Shelf, pre-configured chassis or custom specifications to suit your needs.
