DG has put together a pretty damn good site on suspension, shocks, valving, reading shock dynoes, what shocks to buy, what not to buy and why...
I'd like for anyone ready to pull the trigger on that shiny new coilover set to give this a read or two before spending their hard earned cash.

it isn't for light reading...but honestly, if you're only ready to devote 5 seconds into choosing parts for your suspension, then you're in the wrong thread anyway.
Enjoy and if you've got questions, post them up here and i'll see if I can answer them. (if not, we're both screwed.)
