Friction plate upgrade clutch kit for LSD. 


Fits:
Porsche 991 GT3 / GT3 RS - 2012 to 2019
Porsche 991 GT2 RS - 2016 to 2019

Revitalize Your Vehicle's Performance:
RacingDiffs introduces the ultimate solution to restore the original performance of your Porsche 991 and 991.2 GT3/GT3 RS. Our LSD clutch pack is meticulously designed to rejuvenate your car when factory plates are worn out, eliminating the need for a complete transmission replacement.

Avoid Unnecessary Expenses:
Porsche’s factory setup doesn’t offer replacement plates, compelling owners to replace the whole transmission—an immensely costly and unnecessary endeavor. With RacingDiffs, replace only what’s needed, ensuring other flawlessly working gearbox components remain undisturbed, saving you tremendous costs.

Superior Molybdenum-Ceramic Friction Layer:
Unlike the factory plates that come with paper-like friction material, RacingDiffs clutch plates are fortified with a superior molybdenum-ceramic friction layer. This enhancement ensures a robust and enduring performance, substantially outperforming the conventional materials used in standard plates.

Race-Proven, Heavy-Duty Technology:
Embrace the confidence of race-proven technology. Our LSD clutch pack is built for heavy-duty performance, providing a resilient and reliable option for those who require the very best in racing technology. Equip your Porsche with components engineered for durability and exceptional performance under rigorous driving conditions.

Kit Includes:

  • High-Performance Clutch/Friction Discs x 6
  • Heavy-Duty Dog Ear Steel Plates x 7
  • Longer actuator pin  x 8

Innovative and Efficient:
The clutch discs are strategically perforated for optimal cooling and viscosity, preventing unwanted oil build-up, and ensuring consistent and efficient operation under various driving conditions. Trust in a clutch pack that exemplifies innovative engineering and ultimate performance.

Please Note:
Friction plate upgrade kit should only be fitted by someone with the relevant knowledge and experience.

How to tell if your differential bearings need replacing?
Characteristic noise from differential/transmission occurs during acceleration and coast (engine breaking). To distinguish differential bearing noise from wheel bearing noise steer left-right like you are warming up the tyres for a race.

If the noise changes its intensity then it is a wheel bearing. If intensity of the noise remains the same, this means the differential bearings need to be replaced.

RacingDiffs Components are OEM quality.

Volkswagen Touareg 2002-2010 (all engines with 6-speed gearbox)
