From the RAM Web page:

"A lighter flywheel creates less inertia at launch, but will accelerate quicker through the gears. In order to effectively use a lighter flywheel, you must consider the car weight, operating RPM of the engine, and most importantly, the gearing".

This is exactly why a 2,300lb car with 400hp and 3.73 gears is idealy suited for an aluminum flywheel. A Cobra by definition is a competition car. They go like stink with these flywheels.
