The best way to gain a prominent advantage over the competition is install the AC Schnitzer Limited-Slip Differential. The smooth consistent distribution of power to the wheels with an LSD puts the power-to-the-ground and maximizes your vehicle's traction. A must for any car that looks to enhance performance!
What exactly does an LSD do you ask? well without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have).
An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling.
