Breaking in a brand-new twin-disc clutch is an absolute requirement specified by every major clutch manufacturer to ensure proper bedding of the friction materials against the flywheel and floating plates. Skipping the break-in period and subjecting a fresh multi-disc unit to immediate high-rpm launches or aggressive track driving generates extreme localized heat, causing uneven material transfer, severe glazing, and premature component failure. Completing a conservative break-in mileage window allows the metal and friction surfaces to seat together uniformly, securing maximum torque capacity and smooth engagement over the life of the clutch.
