Good idea !
I'm almost done polishing the housing, going to send it to L.A.
and have it anodized either purple or blue. I want this install
to look amazing. I'm going to polish the redrive as well.
Tony
hi Tony, if you use a series 5 flywheel on a series 4 rotors you will
have an out of balance engine. take care wyo. walt
I don't think he means flywheel walt. I think he means auto TX flex
plate. Nobody flys a flywheel. Too heavy.
Of course the rear counter weight must be correct.
