Springs

What is the difference in the spring rates. For example 325lb, 300lb, 275lb what does this stand for, and if I wanted to lower the car 1 or 2 inches which rate would be good for that.

Doesn't work that way. I assume you have or are looking @ QA1's given your numbers. Springs support a car, the car has a given weight. If you don't want to run out of suspension travel you need to increase rates of the springs as you go lower on height. None of those springs are stiff enough to lower 1-2". Stock springs are 292-310 on most cars, you are talking about roughly stock rate with much less wheel travel.

Lowering springs also vary in rate. Some are way too low for the rate they have. Some aren't. We have our own made, but there are others that don't suck terribly, and some that do.
