Alfa Romeo 75 / GTA / Spider - LSD discs – track pack (Stg 2)

Alfa Romeo 75 / GTA / Spider - LSD discs – track pack (Stg 2), RacingDiffs part no. RD4002. The kit replaces the friction and steel plates of the factory limited slip differential with RacingDiffs plates made from heat-treated tool steel with a molybdenum-ceramic coating.

• High preload setup: The preload shims provide approximately 100–110 Nm of initial torque , eliminating free play inside the differential and extending clutch life.
• Adjustable performance option: The Stage 2 Track Pack includes a multi-variation ramp set for tuning differential locking characteristics to suit your driving style.
