Up to now, M-Chassis owners have had to make do with touring car aluminum dampers when up grading their cars. Tamiya has now developed this set of 4 dampers specifically for the M-Chassis, featuring damper cylinders and damper rods that are 2mm shorter. As a result, the chassis' ride height is lowered and damper stroke can be more accurately customized. A hard black coating reduces friction and serves as a nice contrast to the blue damper caps and included white damper springs.
