Tilton BMW S5X Flywheel, accepts Tilton step type 7.25" (184mm) clutches. The flywheels are tapped 5/16 UNF for clutch mounitng.
Since 1973 Tilton have been manufacturing lightweight flywheels. Initially made from aluminium as technology in racing advanced, and the demand for stronger and lower inertia flywheels grew, Tilton began machining flywheels from billet steel.
Today, Tilton flywheels are subjected to some of the most gruelling racing conditions. They can be found on NASCAR Cup engines, GT cars competing in the 24 Hours of Le Mans and most other forms of racing.
Utilising Tilton’s 35+ years of experience, flywheels are designed using the latest CAD software and are fully optimized for strength and inertia using Finite Element Analysis (FEA). CNC machined from billet steel, Tilton flywheels offer precision balance, high strength and low inertia. After machining, flywheels received a surface heat treatment for the ultimate in strength and wear resistance.
During the last 35 years, Tilton has engineered over 1000 flywheels for racing and high performance applications.
