A great upgrade for drivers looking for added acceleration and grip for their E46 Non-M model cars.

Changing your cars gearing is one of the most effective performance improvements you can make for the money. For example, swapping from a 3.15 to 3.46 ratio will give your car 10% more torque delivered to the rear wheels! All of our differentials are limited slip units, meaning that both wheels pull - no more wheel spin. We will exchange your current differential for a unit built exactly to your specification. We have every ring and pinion ratio available including extra-short Motorsport ratios.

We have seven different types of limited slip units available to suit your particular needs**:

  • Open - Replacement differential based on factory specs.
  • 2 Clutch - Based off the factory limited slip carrier, this unit is great for street use and is easy on the wallet.
  • 3 Clutch - This 3 clutch unit is designed to further increase the locking abilities of the differential for more aggressive traction and grip. Great for street cars seeing numerous track days per year.
  • 3 Clutch with Custom Engaging Ramp Angles - Our best selling carrier type. The carrier incorporates custom ramp angles built into the carrier for an engagement that is more substantial and track oriented. This unit offers excellent turn-in and the abilities to lay down some serious power earlier during track-out. The unit has proved to greatly reduce track times and as a result, created some very happy customers!
  • Diffsonline Helical - The same action as the Quaife but better! Smoother engagement, improved torque, and better gears make this differential never fully lock and the best helical available.
  • Quaife - Unlike a conventional plate-style limited slip differential, the Quaife Helical LSD differential relies on gears rather than clutch plates for its operation. The Quaife helical LSD never locks harshly with a set pre-load of wheel slip across the driven axle. Rather, the Quaife Helical LSD automatically biases the torque away from the spinning wheel across the axle to a constantly varying degree, never locking completely.
  • Race Only LSD Carrier - Lower reciprocating mass helps to give you a competitive edge over the competition. The unit uses 6 clutches and single driven ramps for what we believe to be, the best working, most tunable limited slip on the market. The preload is controlled by coil springs so as the unit wears, preload is not lost.

REMĀ® Ring & Pinion polishing is available for lowering operating temps and reducing driveline loses by reducing friction. Additional charges apply

$95 flat rate shipping/packaging fee.

$400 core charge is not included in price and will be added during processing. Core charge will be refunded upon receipt of your rebuild-able core***. Core MUST be received within two weeks of delivery of replacement unit.

Selecting the best differential type for your application can be a difficult task considering the amount of ratios and limited slip carriers. Please feel free to contact your BimmerWorld sales representative to discuss the best differential for your application.

The ability to rebuild the returned differential will be decided by the differential builder.
