Lightened flywheel? Any real benefit??

Horrible. No-one wants to experience this in a transverse car, in an inline car it would be horrific.

Exactly, which is why we shouldn't be lightening cast flywheels.

This should answer your questions.

Also, it should be pointed out that surface temperatures on flywheels often reach 700C. Before you consider an aluminium flywheel check out the alloy's properties at those temperatures. It may head you in the direction of a steel one.

Spec do an aluminium flywheel and a range of clutches to fit your car.
