Lightweight flywheel options and selection criteria.

i ran a lightweight aluminum wheel from 10,000 rpm behind my 318 in the 64 and 65 darts. commando box (3.09 1st) and 3.55's out back.

absolutely wonderful on the road course and auto-x. a real chore to drive on the street. with a race style on/off clutch it was nearly undriveable in traffic.

i'd steer away from a full aluminum wheel and go with a lighter than stock steel unit for your application.
