PAR design and manufacture flywheels our of billet chromoly, high tensile steel. All flywheels are specifically designed and calculated with a reduced weight to maintain optimum torque and an increased throttle response. The flywheels are also designed with maximum structural stability to accommodate large clamping forces produced from performance pressure plates. The flywheels also possess great heat transfer characteristics to minimise clutch face heat. From our experience, these characteristics cannot be achieved by the lightest flywheels – this is why our flywheels are not made to be the lightest, but to a calculated weight.
