TAMIYA M07 Performance Side Stiffener Racing Upgrade M07-08 by 3Racing  [M07-08]

Racing-oriented side stiffener for M07

A race-focused side stiffener engineered to alter torsional rigidity on the TAMIYA M07 chassis. The component is designed to interface with factory M07 side plate fixings and create a controlled structural link between the left and right side plates for more consistent behaviour under corner load.

From a setup perspective the stiffener allows precise tuning of lateral chassis response: increasing side stiffness can reduce unpredictable flex at high cornering loads and sharpen turn-in stability, helping lap-to-lap consistency in competitive conditions. Changes should be evaluated alongside spring and antiroll bar settings.

Installation follows standard M07 maintenance steps, requiring body removal and access to side plate fasteners. Use the Tamiya specified screw sizes and torque values to ensure repeatable fitment; no modification of servo, ESC or motor mounts is required.

Use this stiffener as a targeted tuning item when seeking tighter lateral control from an M07; document each change and test under representative track conditions.
