If you end up unhappy, you'll chase your tail trying to figure out which change threw everything out of whack.

I'd do the spring, based on your comments below (taking corners harder), than consider revalving the shocks (if you can articulate what you still want to change). I would agree with the comments others made...you'll take corners faster if you spent more time at the track, rather than adding 100 lbs of spring....

I'm running 700f/800r with the sport valve setup and still I'm going in to have my dampeners tightened. The car still rides TOO NICE. IMO the Stasis setup is so sweet you can run higher spring rates with sport valving and fairly tight dampeners and still have a car that rides real nice, but what I would do is this: swap out your valves for the sport setup and tighten your dampeners a bit (to 50% or even 75% depending on how much you'd like to feel the road). Then see how the car feels. It should be fine at that point. If for some reason you still think you need tighter springs, talk to Stasis again. BTW, I'm in NoCal if you want to drive in my car and see what it feels like.
