The Tamiya 54766 Aluminum Counter Shaft offers a simple way to reduce mass on the M-07 Concept chassis. Swapping the original steel shaft (4.3 grams) for this aluminium unit (2.8 grams) lowers rotational weight and helps the car react quicker to steering inputs.
This counter shaft is tailored for the M-07 Concept gearbox and installs without complex alterations. It is a straightforward swap suited to hobbyists who want to refine their car's handling without extensive teardown.
Aluminium cuts rotating weight and can contribute to better acceleration and corner entry. The lighter shaft assists in creating a more balanced setup that many racers prefer for technical tracks.
