Stay away from lightweight flywheels unless you plan to have the crank/flywheel balanced. The 986 does not have a harmonic balancer. Crank balance is achieved with the dual mass flywheel, so installing a lightweight flywheel could result in vibrations and even broken crankshafts.

I considered one years ago...until Jake Raby posted pictures of broken crankshafts and the resulting carnage.
