I have heard the Skunk2 coilovers are super stiff.
I, however, helped a buddy install KYB AGX's with Neuspeed Sport springs and the ride afterwards was really nice. Great height too. He spent around $450 for the struts and springs, so it is a quality setup for cheap.
Get it aligned afterwards and if they say you need a camber kit, buy one. If you are slamming it, you will definitely need one. 1.5" and higher all depends on how out of spec it is at the alignment shop.
I assume you are just getting the setup for a lowering and some improved cornering but not really much track time?
