OT-215: The OT-215 lug drive clutches have a track bias so are aimed at track day or streetable competition cars that are regularly driven at track based events and occasionally on the road and when compared with a 7.25” clutch with an equivalent number of disc the OT-215 8.5” Cerametallic Clutches provide approximately 50% more mass for increased heat capacity to keep overall clutch temperatures down, while providing higher torque capacity and better modulation.
ST-215: Tilton has now applied their nearly 50 years of experience in racing clutches to develop the ST-215 line of twin-disc clutch kits for the high-performance street market. Unlike many of the “performance clutches” on the market, ST-215 clutches were designed from the ground up as a true performance twin-disc clutch and not an OEM-type stamped steel pressure plate with a floater added. Featuring an aluminum clutch cover that shares technology from Tilton’s championship-winning line of OT- Series racing clutches, ST-215 clutches feature heavy-duty straps that attach the pressure plate and floater plate to minimize noise. ST-215 clutches are available with either sprung-hub organic discs for street applications or solid-hub cerametallic discs for street/strip applications.
