Cusco TC Tension Rods — S30Z (Japan Import)
These are the Cusco TC Rods installed on ZSM’s personal 240Z — sourced directly from Japan and part of a suspension package for the S30Z platform.
Tension control rods are a foundational suspension component. They control fore-aft movement of the front lower control arm under braking and acceleration, directly affecting caster and the dynamic behavior of the front end. Getting this right is a prerequisite for dialing in everything else.
Part of the ZSM S30Z Suspension Development Program
ZSM is using these Cusco TC Rods alongside the stock suspension to test and collect alignment data specific to the S30Z chassis. The goal is to understand what settings the S30 chassis responds to best — not just bolt on parts, but actually tune the car into something more than a parts list.
