There has been a lot of talk about front and rear shocks and some good information. Not much has been discussed about front and rear spring selection (coil overs).

Generally, from what I remember, the spring rate is whatever is needed to just hold the car up. Is this still true?

My truck is 58/42% at 3300 lbs which yields 1,914/1,386 weight.

What would be the front and rear spring rates that would be optimal?
