Want to lose nearly 13 pounds of unsprung weight? The Cooper S Factory Dual Mass Flywheel weighs in at nearly 27 lbs while this lightweight flywheel weighs in at 14.5 lbs. Imagine what reducing that much unsprung weight will for your MINI. SPEC billet aluminum flywheels are recommended as a replacement for OEM cast steel flywheels for use in street and racing applications.
The spec lightweight aluminum flywheel was designed and tuned specific to the MINI engine, torque values, weight and HP. Best when used with a upgraded Spec clutch, the insall time is likely going to fairly high, so while you've got the car apart, it would be a good idea to do the clutch upgrade at the same time.
By decreasing unspung weight, like wheels and tires, a lightweight flywheel can actually free up horse power that was being robbed by heavy flywheels and tire/wheel combinations. When going to a lighter flywheel, expect throttle response to be quicker and revs to raise a bit quicker, also there may be a slight increase in engine noise as well as slight drop in RPM's between gears due to the rotational mass being lower.
SPEC billet aluminum flywheels are also CNC machined and exceed SFI standards for high stress racing applications. These units are recommended for highly modified street or racing vehicles, and for mildly modified street cars that can benefit from reduced rotating mass without the loss of daily drivability.
The body of the flywheel is made of tempered aluminum for ultimate strength and lightest possible weight. The 1/4 inch thick friction plate is a 1050 high carbon alloy, for incredible durability with any friction disc material, even iron. The plates are secured to the body by stainless steel rivets. The ring gears are pressed on and secured with grade 10 fasteners.
