Thx Howster. I did a lot of research on coilovers. There a few options but you have to go more basic or do a custom order for something to the level of the KW V3's at this time. Post any questions you have. Do a decent alignment too. I recommend looking at the definitive alignment thread for more info.
I am very happy with the set up. The independent adjustability is great, and settings make a big difference in how the car rides. These coilovers aren't overly dumbed down where the adjustability doesn't make much of a difference.
I find the car gets a lot more looks now. And the impact on warranty is minimal. It is a win win situation. I did this as my first mod, and I recommend to everyone that this be their first mod, especially on GXP's where engine mods aren't doing a lot without getting tunes. And even at that the ECM still isn't cracked properly.
I can scare the crap out of passengers with the cornering ability of the car now.
With more seat time I find the car has more road feel. There is a bit more harshness at the beginning of bumps, but if you are on a bumpy street/section the car feels very similar to stock. This is at the recommended KW V3 settings. Backing off the compression will make the car feel more like stock overall too. FYI I'm back to stock KW V3 recomended settings.
I did some more ride height adjustment this morning. It looks likes things have settled making adjustment much easier. And I'm where I want to be for ride height at this time; about 1.4-1.5 inches lower than stock. Note that rear ride height is very dependent on the fuel load.
