changing aspects of the suspension
how can u change the spring rates of a spring + shock combination? and can you change the dampening rate of a non adjustable shock? are spring rates and dampening rates told to the company when you order so they can send yo the right ones?

Well, if you can dismantle the shock & change the valves inside, then most likely you can't put it all back together...

how do you know which spring rate is just right for you? and how can you make a non adjustable shock match the spring rate of the spring?
I"m assuming that companies like eibach and H&r make springs that are a happy medium among enthusiasts, with companies like tein and other hardcore spring makers produce and sell springs that have a spring rate more suitable for the track. right?

Look for spring rates published at their websites. That way you can compare one against another with actual numbers. Watch for some to be listed in newtons-per-meter, some in pounds-per-inch...

The correct spring rate will depend on your vehicle and its use. The shock valving depends on the spring and its use. If you look at really expensive shock's graphs (plots force versus velocity) the adjustment range is pretty small. In this case, the valving is matched to the behavior needed and only small adjustments are needed. So don't get all fussed out about adjustability. Contrary to what most people think, changing the rebound damping of a shock is easier to "feel" adjustments made compared to compression: the compression stroke only damps the unsprung mass of the vehicle, while the rebound stroke damps the sprung mass (much more). This is easier to see if you think of the suspension moving rather than the entire car. So it's best to talk to whoever you buy your shocks from and have a custom valving for the springs to be used a bunch of other variables. Adjustable shocks are nice for making small changes. You can't expect big changes out of them , though.

Most Hondas racers buy custom size and rate springs from companies like Hypercoil or Eibach. You can get away with the springs supplied in a coilover kit, plus it costs little to change the springs out.
