Tamiya 54766 M-07 Aluminium Counter Shaft - Performance Part  [54766]

Shed rotating mass to sharpen the M-07 Concept

The Tamiya 54766 Aluminum Counter Shaft is a compact upgrade aimed at reducing the rotating mass in the M-07 Concept chassis. The aluminium item weighs 2.8 grams versus the original steel 4.3 grams, helping to make the model feel livelier under acceleration and during direction changes.

Compatibility with the M-07 gearbox

Specifically made for the M-07 Concept, this counter shaft fits the stock gearbox layout. Hobbyists can perform the swap with common tools and minimal disassembly, keeping the car setup largely unchanged.

Performance gains from a lighter shaft

Switching to aluminium lowers inertia in the drivetrain which can improve acceleration and turn-in. This hop-up offers a subtle but useful way to refine on-track behaviour without altering major components.
