Now that people understand the basic difference between superchargers and
turbochargers, maybe the knowledgable can enlighten us about springs.  In
particular, what are the pros and cons of constant rate springs (where
F = kx and k is a constant) versus progressive rate springs (where k is not
a constant and instead increases with x)?  Also what are the tradeoffs
involved in higher/lower rate springs (re: potholes and ride) and how does
this translate for progressive rate springs?  Since my car has excessive
nose dive upon hard stopping, I assume the correct solution is higher rate
springs.  So how does one go about determining how much stiffer?  Finally
how do springs rates interact with shocks?

If you are not tired out after answering all the above questions, you might
also throw in some tidbits on shocks like which brands people prefer
(e.g. Koni, KYB, Bilstein, etc.), the pros/cons of gas versus hydraulic
shocks, etc.
