$1150 for the kit (try Suncoast or Sunset, I actually got mine through Wheel Enhancement)
Fitting + alignment $600 at Johnsons Alignment in Torrance CA. In principle you can do it yourself - I chose to get a pro.

 

Is this a coil-over system or a performance set of shocks/struts and springs, oh and you get the sway bars that's a plus? In looking at it it has no adjustment.

 

It's the Porsche "Sport" option from the European market. Roughly 10% stiffer, 10-20mm lower, with substantially stiffer swaybars. The set includes springs, shocks and sways, but it's not adjustable. I've put 120 miles of mainly freeway driving on it today visiting another office, and the ride is barely affected while the steering seems vastly improved. Front-end float is also improved, but after 80k on the original shocks, I suspect that any new shocks would have been an improvement

Plus side for me is that it's made by Porsche, which makes me happy and may also be handy for avoiding being bumped up too many PCA AutoX classes (I'm not 100% sure about that, though)

 

Hmmm you bring-up a good point about PCA classes. Although I haven't been to any yet, I am going to Thunderhill in August to watch the Golden Gate chapter race, have some friends that will be up there the weekend. So I will be doing more checking into classes, rules etc. when I am there.
