Revoknuckle isn't for reducing torque steer, its for providing a more positive meathod of putting alot of power through the front wheels.
It is said to reduce it and from watching top gear it didn't look "too bad"
compared to the mk1 Focus RS, which if he'd let go of the wheel would have killed him! lol
But the point in the Revoknuckle system is power transfer,not to reduce torque steer.
