Porsche 991 GT3 / GT3 RS - 2012 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:
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.

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.
