RTMG Performance release a torsen limited slip differential for 02M / 02Q Manual gearboxes of VW Group.
The RTMG Torsen is Type A which use helical gears. The Torsen differential works just like a conventional differential but can lock up if a torque imbalance occurs.
During acceleration under asymmetric traction conditions, so long as the higher traction side can handle the higher percentage of applied torque, no relative wheelspin will occur.
When the traction difference exceeds the TBR, the slower output side of the differential receives the tractive torque of the faster wheel multiplied by the TBR any extra torque remaining from applied torque contributes to the angular acceleration of the faster output side of the differential.
