Schumacher Mi Range Gear Diff by Spec R

Schumacher has announced a new gear diff for the Mi4 range of cars. Made by World Champion gear diff suppliers Spec R, this will fit directly into the Mi4CX but will also fit older cars with Blade-style driveshafts such as the Mi3, Mi3.5, Mi4 and Mi4LP. In testing, the team drivers have been using Schumacher 70 to 100wt shock oil in the diff for best results. Very little maintenance is required compared to regular ball diff under high load conditions with modern powerful brushless systems.
