What is tire shake? I have never had the same answer from anyone I thought would know. There seems to be a belief that clutch operation has something to do with it, but what about shake with a converter or does it happen with a converter? Seems to be a more common problem in Pro Stock, now, for whatever reason. What causes it would be tough to avoid, if you don't know what it is in the 1st place and there may be no way to avoid it. I've heard people say, that car used to shake all the time, this new car doesn't shake at all.....no wonder you don't get the same answer about what it is.
