Has anybody lighten a stock flywheel?
Has anybody lighten a stock flywheel? Is it a good idea? Who can do it? Any recommendation would be great. I know the pros about it (quicker spin-up time, better throttle responds ect..., what about the cons? This will be a daily driver and DE car.
Thanks John |

I'm no expert in this but I understand that a pre-964 flywheel ( you didn't mention model year of your car) isn't all that heavy and you can get the same effect with a lighter pressure plate and clutch.
Anyone? - Wil

I had the flywheel lightened on my 73 2.5, and will do the 3.0 when it comes time for reworking.
took it to a local speed shop. downside, when combined with a rsr clutch pkg, it requires a deft touch to engage smoothly. that said, the benefits far outweight the downside. in my case anyway. flame away Bill K

Patrick sells these. In fact, I was just on the phone with them yesterday on a different matter. The guy mentioned that they carve scallops out of the rim & have to be very very careful re balancing as the force is on the order of 500 lbs. Remember - the rim is the critical area. I would never do this myself or have anyone but an expert lighten one. Wevo & SRP also have them, IIRC.
There are problems with using them on the street or with DME systems - hit the ol' search button for more.
