The Sterling RX frame and suspension kit were developed together to work in harmony on the track or on the street. The RX kit gives you everything you need to build your car, except a select number of off the shelf parts which you choose to fit your personal driving style. The chassis is a full rolling kit with suspension included. Left-hand and right-hand drive configuration available.
