TAMIYA M07 Circuit Side Stiffener Tuning Part M07-08 by 3Racing  [M07-08]

Overview of the M07 side stiffener

A compact side stiffener made for the TAMIYA M07 chassis to change chassis torsional characteristics and give more precise setup control. It mounts to the existing M07 side plate points and creates a reinforced path between both sides.

The accessory is used to refine handling balance: adding side stiffness can reduce lateral flex during corner entry and mid-corner, helping the car track more consistently. The actual effect depends on tyre choice and other setup elements.

Installation follows basic M07 service steps, requiring body removal and access to the side plate screws. Use the recommended Tamiya screw sizes and torque values; no changes to servo, ESC or motor mounts are required.

Use the stiffener as a tuning option when seeking a firmer chassis feel from an M07; evaluate one change at a time so you can compare results reliably.
