springs can only get you so far....other companies i have called about different spring rates claim their dampers are only viable for +-2kg from the original spring..so if you bought 14/10 coilovers, you could go as soft as 12/8 or hard as 16/12...
i am unsure on how bc can offer any spring rate unless they were changing the dampers to suit the spring =/
geek, have you had any more luck with adjusting your coilovers??

Any reputable brand will safely tell you 10% spring rate change is fine with whatever valving they use. 20% max on some brands. Most 'budget' companies (and even a couple of japanese companies) are over-dampened anyway to make up for manufacturing inconsistency.

btw, i was browsing bc racings site looking for info:
Replacement dampers are also priced at 95.00..
I do not know if BC will re-valve your coilovers for free or what since you just bought them so recently. It does say, however:

Q: How much higher can I go up in terms of spring rate before I need to revalve?
A: Our kits are valved to allow an increase of 2k up from our default rates and still maintain acceptable suspension performance. Anything over 2k has to be revalved in order to be run safely and within our specifications.

I'm running the supra higher spring rates 14k/10k and it rides great. My car is relatively low but not dumped (appx 1 finger gap inbetween the tire and fender). My stiffness is at about 3/4 of the way up in the front and back. I relocated my fender well harness and set my height and dampening and haven't touched it in a long time.
You have to also understand that it's hard to compare these to other cars we drive boats that weigh upwards of 3600-3800lbs, comparing these coils on our cars vs an evo is apples to oranges. What I was impressed with and what most people comment on when riding in the car is how well it drives considering it's on full coil-overs.
