Serpent S7XX one-way front diff set
Serpent have introduced their new adjustable one-way front diff set for the S7XX series of 1/10th 200mm on-road cars. The drag-assisted one-way replaces the standard front diff and it enables the driver to still brake and turn in like using a diff, however corner exit drive and change of direction on-throttle is greatly improved. The set is a direct fit on the S750 and it also fits older generation S7XX cars.
