ACTIVE DIFF ON - AND OFF-POWER ACTION

ACTION EFFECT

OFF-POWER

Off-power the Active Diff works the same way as standard

differential, so adjustment is made by using different viscosities of

silicone oil. The softer the oil, the more off-power steering but the

car will be more aggresive.

ON-POWER

The main advantage of the Active Diff is readily apparent when

on-power. The diff becomes harder and more locked when throttle

is applied, giving a lot of forward traction and stability to the car.
