TF spring and shocker kit After extensive testing and development both on road and track Mike has designed two spring and shocker kits that will suit most drivers. Both kits will produce a superior ride to the stock set up reducing the 'choppyness' often associated with the TF suspension. The two kits are colour coded, Blue for road use or Red for a more sporting road and track requirement. The design of the spring and adjustable damper are such that they work together allowing a more compliant spring with better damper rating than the stock set up (rather than excessively stiff spring rates and poor damper performance). The variable adjustment of the damper is crucial to allow varying load and driver requirements putting this design in front of fixed rate dampers currently available. The springs are precision made with ground ends to give precise location and performance in use.
