Spring rate-vs-
Car weight. do you still run the same spring rate if the car weights changes. IE say u have Lg2 or Sams springs and you go from a 3700lbs car to a 3300 car, would u need to change springs for the weight change??

I wouldn't say you "need" to. It really depends more on where the weight has changed. If you lost all the weight in the rear for example you probably would want to run less spring rate in the rear, or vise versa.
