The problem with an open differential is that power is not applied evenly across the drive wheels. The German parts manufacturer AC Schnitzer have a cure for one tire fires and peg-legged burnouts. That is why they have produced a limited slip differential for BMW 1 and 3 series cars as well as the Mini.
There’s no driving pleasure without the right engine power: But what’s the use of pressing the gas pedal hard, if the power doesn’t get to where it’s needed? On rapid acceleration out of corners or in the wet, or on loose surfaces such as ice, snow or dirt, you soon find one wheel spinning helplessly on the spot. For smooth forward progress, AC Schnitzer offers an after-market limited slip differential for the BMW 1-series and 3-series and for the MINI models which will give that extra touch of spirited performance in many scenarios.
The fundamental technical principle is quite simple: if one side of the driving axle is about to slip, the AC Schnitzer limited slip differential transfers up to 75 percent of the "surplus" power to the opposite wheel. "This means that the flow of power is not interrupted, so there is guaranteed constant propulsion in every driving situation", explains AC Schnitzer Technical Director Manfred Wollgarten. For the front-wheel drive MINI, the AC Schnitzer limited slip differential also improves steering behaviour, which becomes even more direct. Thanks to this modification, the Aachen-based tuner achieves faster cornering speeds and a reduced understeer tendency, so the driver can utilize the power reserves of his car in every situation and achieve optimum driving dynamics. With this product, the renowned tuning house is once again demonstrating its competence in the suspension sector.
