Schumacher Mi4 gear diff
Schumacher have 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 drive shafts, such as the Mi3, Mi3.5, Mi4, and Mi4LP. So far in testing their drivers have been using Schumacher 70wt – 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.
