Bad in what way? Noise, ride, handling, traction? Are you using monoleafs, ss springs or stock springs? What shocks?
I have tried everywhere from 1/4" gap to 1 full turn preload with monoleaf springs. Now I just set the left at 0 and the right at 2 flats preload and call it done. I am going to guess that if you are more than 2 flats tighter or looser than this that you are lost and should be working on the shocks instead.
In my post above from TEN years ago I suggested heater hose to soften the noise. That worked but the hose wore out fairly quick. I now have a piece of 1/4"thick flat polyurethane glued to the top of the springs with 3M weatherstrip adhesive. It is holding up much better.
No, sorry, I just meant if it will negatively affect the Caltracs with no preload. I'm not worried about noise, and everything else should be normal with no preload correct? and I'm also most likely keeping the XHD springs, since Calvert said there wouldn't be any problems (although I will probably have to have a little more preload on one side, no biggie at all)
