Friction plate upgrade kit for limited slip differential (LSD) 



Fits:
Porsche 993

Porsche 996 / turbo / GT3
Porsche 997 GT3
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 Clutch/friction discs
• 4 x Hardcore dog ear steel plates
• 2 x Pre-load (spherical) shims

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.

Quaife ATB Helical LSD differential for Porsche 997 is suitable for Porsche 997 models. A direct replacement for the standard Porsche differential, the Quaife ATB Helical LSD differential transforms your car's performance. Unlike a conventional plate-style limited slip differential, the Porsche 997 Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation. The Porsche 997 Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Porsche 997 Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks. The Porsche 997 Quaife ATB Helical LSD differential has many benefits over a standard open differential, including maximising traction and minimizing wheel spin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication. The Porsche 997 Quaife ATB Helical LSD differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards. With over 250 applications, the Quaife ATB Helical LSD differential is second to none. Accept no imitations! Quaife ATB Helical LSD differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment. The Quaife ATB Helical LSD differential for Porsche 997 is also now subject to a lifetime warranty (subject to terms and conditions). Please confirm your application using the attached technical drawing.

Helical LSD differential is suitable for Porsche with G50 gearboxes, to replace the standard open differential. A direct replacement for the standard Porsche differential.

Automatic Torque Biasing Differential enables your car to accelerate quicker and corner faster.

The Differential powers both drive wheels under nearly all conditions. With an ordinary open differential (standard on most cars), precious power is wasted during wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip, along the path of least resistance. The Differential, however, does just the opposite. It senses which wheel has better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.
