Over 1kg lighter than the factory item, the Turbosmart Billet Center Plates are manufactured under tight quality control to very precise tolerances. Tougher wear face provides excellent oil retention properties for side seal longevity and increased engine rigidity, while solid bearing support is ideal for high boost and high RPM applications. Dry sump compatible. Direct bearing oil feed or through traditional dowel oil system. Extensively tested and proven on several cars (most notably the PAC/Turbosmart 6-second MX6) under severe race conditions. Under all circumstances this component showed excellent results.
