I've had my coilovers for about a month now, and I can definitely say they're amazing overall! I had the Skunk2 Pro-S coilovers before this, definitely a giant upgrade in every way. Not one bad thing about them - very easy installation, comes with everything you need, very adjustable, and great dampening. The only downfall is that the 6k rear springs are way too soft for a boosted Si, probably even soft for NA too. I'm definitely looking to get some 10k or 12k in the rears ASAP.

Others feel free to chime in on your experience with their coilovers, especially those with different spring rates!
