Fits:
Porsche 944 - 1982 to 1988 (Early)
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.
Kit Includes:
Friction Plate Upgrade Set
Multi Variation Ramp Set
RacingDiffs Performance LSD clutch plates fit OEM Porsche (ZF) LSD unit without any modifications:
The clutch discs are perforated for better cooling and great viscosity to resist the oil build-up in the holes between dog ear plates as 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.
