Torsen-differential Q2 (limits the slip to 25 % under load, repsectively 30 % without load).
Torsen means "torque sensing" - this differential senses the difference in grip of the two front wheels and assures a progressive transfer of the torque to the wheel with the higher grip and therefor offers a better traction.
The Q2 is very smooth in action - it does not work like a conventional plate LSD which can only work "locked" or "un-locked" - transfers the engine's power continuously and without a snatching of the steering wheel.
The engine's power no longer fizzles out in a grip-less spinning wheel or in the ASR traction control.
The Q2 effectively stops the common wheelspin the JTD and V6 engines often cause when accelerating hard out of a tight bend.
Curves can therefor be passed more quickly and without or less ASR / VDC regulation which results in a loss of engine power and weak acceleration.
The Q2 does not only improve the handling and speed when driving very sportively, it also improves the traction on slippery, muddy and icy roads since it always transfers the engines torque to the wheel with the best grip.
We recommend to have the differential mounted by a trained mechanic!Suitable for the following models / engines:Alfa 147 1.9 JTD and GTAAlfa 156 1.9 JTD, 2.5 V6 24V and GTAAlfa GT 1.9 JTD, 3.2 V6 24VAlfa 166 2.5 V6 24V, 3.0 V6 24V and 3.2 V6 24VSpider/GTV (916) 3.0 V6 24V and 3.2 V6 24V
