RacingDiffs
Based in Serbia, RacingDiffs is a company specialising in the production and repair of automotive differentials. It offers complete differentials, plates, rebuild kits, but also very popular conversion kits to turn an open diff into an LSD. Composed of genuine enthusiasts, the RacingDiffs team has set itself the mission of making performance drivetrain parts accessible to as many people as possible while respecting the highest quality standards.
"All Solutions" LSD Units
RacingDiffs offers high performance and extremely versatile clutch-type limited slip differentials suitable for street or competition use (drift, rally, hill climb, circuit, time attack...). This "all-in-one" solution fits in place of the stock unit and really allows you to obtain a tailor-made handling. These LSDs are fully adjustable and offer a choice of the number of active clutches, initial preload and ramp angles. Locking is adjustable from 25% to 100% on 1.5 or 2 ways. These complete units are available for BMW vehicles with 168mm, 188mm or 210mm differentials.
LSD Conversion Sets
RacingDiffs' flagship product range, the conversion sets enable an open differential to be converted into a limited slip differential (LSD) at a lower cost in order to improve the vehicle's power distribution. Easy to install and very affordable, they increase driving pleasure and are ideal for everyday street use. These sets are made up of steel friction plates and high-strength springs and offer a 25% progressive lock. They are available for a wide range of sporty vehicles from major manufacturers (BMW, Ford, Honda, Nissan, Toyota, VW...).

100% Lock Discs
Used in drift or drag events, the RacingDiffs block discs allow you to permanently lock your differential to 100%. They induce the same feeling as with a welded differential but are much more reliable, are maintenance free and can be exchanged at any time with the original clutches to recover all the performance of your LSD. Extremely solid, these discs are guaranteed for life by RacingDiffs.
Clutch Plate Sets
Whether it is for a rebuild or an upgrade, RacingDiffs produces high quality replacement LSD clutch plates. Tried and tested at the highest levels of motorsport, these parts will considerably improve the performance of your vehicle. The plates have a higher coefficient of friction than the stock pieces, allow for greater locking, offer superior resistance to heat and have an extended service life. Some sets are available in different variants (standard, sport, track, race...) to perfectly fit your needs.
Repair Kits
Has your differential become noisy over time? RacingDiffs offers an effective and long-lasting solution to this problem with its OE quality service kit containing replacement bearings (ball or tapered roller) and oil seals. Available for BMW MM, L, K and Motorsport differentials, these sets restore used mechanisms to full efficiency and eliminate operating noises due to wear.
Why Would You Want an LSD?
As a differential specialist, RacingDiffs is at the forefront of recognising all the benefits of a limited slip differential, whether in sports driving or in competition. This mechanical device corrects the distribution of engine torque on the driving wheels. It is able to compensate for a loss of grip by redistributing more power to the wheel with the greatest grip on the road or track. The result is a considerable gain in traction for improved cornering and acceleration.
