Friction plate upgrade kit for limited-slip differential (LSD) – Porsche 911 / 968

Track day and race-inspired upgrade kit for the original Porsche limited-slip differential (LSD). Replaces the standard friction discs with higher-performance components for improved traction, increased durability, and more precise response. Fits Porsche 911 (915 transmission) and Porsche 968 with M220 LSD.

Details at a glance

• Performance friction disc kit for OEM ZF limited-slip differentials
• Improved LSD activation and deactivation behavior
• Noticeably higher traction under load
• Ideal for track days, sporty road driving and competition use
• No modification to the original LSD is necessary.
• Suitable for vehicles with Porsche LSD (M220 / 40% locking effect)

Description

This friction plate upgrade kit is specifically designed for Porsche vehicles with a factory-installed limited-slip differential (option code M220) and is aimed at drivers seeking a noticeable increase in performance and more precise vehicle control. The kit replaces the worn or softened standard discs with higher-quality, higher-friction components.

Thanks to the optimized material pairing and increased friction, traction is improved, especially when accelerating out of corners, during rapid load changes, and under intense thermal stress. The limited-slip differential builds up its locking effect more stably and evenly, resulting in more grip and better drivability.

The upgrade is fully compatible with the original ZF-LSD and can be installed without any additional modifications. Ideal for restored vehicles, sport-driven road cars, or for use on racetracks.
