Omnimofo, I got my installed, corner weighted, aligned (2 weeks after install) and camber checked...all for $65000NT, just over $2000US. I've seen the KW V3s online listed for about the same price without the install etc.
Stasis are cheaper,and people love them too. Actually, come to think of it, I haven't really heard of anyone complaining about coilovers!

They really do rock out the performance and looks of your car. I personally tried two Golf GTIs...with with H&Rs and the others with the KWs. For me, there really wasn't a question. The KW V3s gave better cornering performance AND a softer ride. The H&Rs could really 'clunk' over some bumps that the KWs can handle. The V3s let you adjust dampen, height, and compression. The V1s and V2s have similar performance, but not as much adjustability. The V1s are priced similar to Konis.
Sounds like you have a good order of the mods you want to do though!

The chip is CRITICAL, just watch your warranty with it.
