Friction Plate Set for Limited Slip Differential (ZF) - Porsche 911 / 968

Trackday and race-inspired upgrade kit for the original Porsche limited-slip differential (LSD). Replaces the stock friction discs with higher-performance components for better traction, increased durability, and more precise response. Suitable for Porsche 911 (915 gearbox) and Porsche 968 with M220 LSD.

Details at a glance

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

Description

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

Thanks to the optimized material pairing and increased friction force, 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, leading to more grip and better drivability.

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