Subject: Re: C4 Clutch / Flywheel by Josh on 2008/4/7 1:30:43 Your 91 has holes around the perimeter of the stock flywheel to facilitate balancing if necessary. Most cars don't have any weights in the holes, but do to the nature of assembly line manufacturing, some cars needed some fine tuning after they were built; those cars will have weights pounded/screwed into some of the holes. If your 91 has no holes filled on the flywheel, the stock GM balance (which is 32 grams, not zero) was good enough. If there are holes filled with weights, you'll need to add the appropriate amount of weight in the appropriate spot on the flywheel. If you have a neutral balance flywheel right now, it theoretically won't work without adding the 32 grams that GM put on the stock flywheel. However, in the past, I've done clutches in other cars where I replaced a counterweighted flywheel with a neutral flywheel. I never had an issue. I can't say that you won't have one, but in the past I have had success with a zero balance flywheel. |
