If you get the Skunk2s returned ok then buy the GCs and Koni Yellows. The special thing about Koni Yellows is two-fold: 1) you ALWAYS want an adjustable shock, so when you want to spend a night of hard cornering, simply stiffen the damping on the shock or when you have a long freeway drive ahead of you soften the damping so you don't feel every little bump (via external knob), and 2) Koni Yellows are more aggressively valved than their Red counterparts, so you can lower your car more. With a more aggressively valved shock, it can properly dampen the high spring rates of GCs or Skunk2s. Also, if shopresponse won't let you return the coilovers, just put Koni Yellows on the Skunk2s. Your ride will still be very smooth. The only difference between GCs and Skunk2s are that GCs use Eibach springs on their coilovers and Skunk2 makes their own, which are actually excellent. So either way, your ride will be pretty dope. Let me know if any of that was confusing. I know I'm rambling on. Peace
