Spring Rate/wheel Rate

Hey Man, Thanks for looking at my setup. So, you're saying to stick with the factory spring rates? How do you calculate the WHEEL rate versus the SPRING rate. Or visa versa?

The general plan is to just improve what the General(GM) put in it to begin with. I'm just hard headed and stubborn about cutting the suspension out and starting fresh, I want to keep the stock design and improve it to eliminate some of bad attributes.

When these old trucks are well lubed(solid leaf spring bushings) and with taller sidewall tires the front ride is not too bad. The rear on the other hand is way too stiff and jouncy without any load. Bumpsteer and steering box slop, along body roll are the other poor attributes.

The rack & pinion assembly I'm going to use is supposed to eliminate a great deal of the bumpsteer and make the steering more precise. The front and rear sway bars will eliminate alot of the body roll. I'm close to what I want, but need help in choosing the proper SPRING rates.

This is a street cruiser, its not like I'm going to try and run an autocross course with it. The ladder bar thing was just a discussion, I'll very likely run a slide-link traction bar system to prevent wheel hop and get a half decent holeshot if I want to bring it to the drags on Friday night.

Sorry about the long wind, but I'm trying to get help it the areas that I'm not too knowledgeable about. Nolan
