The 3Racing F113-307 side spring set provides tuners with a focused method to adjust roll stiffness and transient behavior on the F113 chassis. It is intended for setup iterations where controlled, repeatable changes to handling are required for competitive running.
Use the side springs to influence weight transfer timing and lateral load distribution without changing damper valving. Small incremental changes can help isolate the effects of roll stiffness on understeer and turn-in response.
Inspect seating and retainers during installation to ensure consistent preload and to avoid binding. Regular checks preserve predictable spring behaviour across practice and race sessions.
