Lunati 704

If you've got the recommended springs, i doubt that's the problem.

Has this been a ongoing issue, or a recent development? What are the symptoms that lead you to think this?

Are you getting noise upstairs, or is the car bucking/surging near the shift points? Do you have stock rockers or adj. and what are your shift points.

My first thought was you may have too much preload, but it could be several things and some more info would only help.
