For cars with Porsche LSD fitted - Option Code M220 (Locking differential 40 %)
Upgrade the standard Porsche LSD to these Track Day / Race inspired components for improved, performance traction.
Our plates also provide more grip and superior durability, which makes them an absolute must have for everybody who visits the track regularly.
RacingDiffs Performance LSD clutch plates fits OEM Porsche LSD unit without any modifications:
This kit contains:
4 x Moly- Ceramics Clutch/friction discs
4 x Hardcore dog ear steel plates
Clutches are perforated for better cooling and great viscosity to resist the oil build-up in the holes between dog ear plates.
It is well known that drilled brake discs improve cooling over solid discs, it is the same with the LSD clutch discs.
The highest quality thermally processed tool steel is used which differentiates our products from any others on the market.
During the final steps of production the clutch plates are coated with special Molybdenum-Ceramic compound which optimizes the best ratio of friction coefficient and durability. This drastically reduces material wear and warping under extreme conditions providing our clutch plates the best possible longevity.
We mastered knowledge in the field of friction materials and coatings, which is the cornerstone of the quality of our products.
All of our clutch plates are thoroughly tested and are currently being used in various racing cars throughout Europe and USA including track, hill climb and rally.
Please Note:
Friction plate upgrade kit should only be fitted by someone with the relevant knowledge and experience.

Benefits of a limited-slip differential
The main advantage of a limited-slip differential is demonstrated by considering the case of a standard (or "open") differential in off-roading situations where one wheel has no contact with the ground. In such a case (with a standard differential), the non-contacting wheel will receive 100% of the power, while the contacting wheel will remain stationary. The torque transmitted will be equal at both wheels, and therefore, will not exceed the threshold of torque needed to move the wheel with traction. In this situation, a limited-slip differential prevents 100% of the power from being allocated to one wheel, and thereby keeping both wheels in powered rotation.
