LuK says it pays to ask about vehicle history when a high performance car comes in for a clutch replacement as it could have been highly tuned, had the EMS re-mapped or even had modifications made to the engine. In some of these cases a modified specialist clutch will be required. If a standard type clutch is fitted you may well find yourself dealing with clutch slip! Remember, many OE suppliers only sell clutches suitable for standard ‘factory’ spec vehicles.
Another tip is to also check the flywheel for signs of heat stress and cracking due to excessive heat build up, replacing if necessary.
