keep in mind too that your tire setup will play a large role in the ideal damper setting, since it alters the effective spring rate as well IE, a tire with a softer sidewall (Toyo T1R for example) can get away with a bit stiffer of a setting vs, say, an Advan or most Bridgestones (stiffer tire wall)

100% of $2000 = $2000
$2000+$2000 = $4000

so if you start with your budget, now you're over by 2x.

:P

lol - see now you're doing government math

1 hammer - $8700.00
1 nail - $3200

total for hammer and nail - $23,500 = new line item in appropriations bill lolololol

So they are down to the RS and the Hypermax III? I can somewhat understand dropping the II, but not the LS+.

Good point. I'm running Bridgestone Potenza RE050A's. Great sticky street tires and yes, have a stiffer sidewall than most.

Dklau33 I'm in the bay area also, maybe I could get a ride in your Z?

With comments from all of those posts, I have narrowed down my requirements to the following:
1. My Z is my daily driver, so it has to be somewhat streetable and pass the 'wife' test
2. I want to get out and do some track days (hpde, road course but no 1/4 mile tracks)
3. I want the rear shocks to be inverted so the adjustments are NOT at the top. (my other car had coilovers and I had to drill through the tub and use a long t-handle allen wrench to make adjustments, it was do-able but a PITA)
4. I want linear springs and in a bias as Gsedan and Z1 have mentioned (front mid-500's and rear around 500) or at least in that neighborhood
5. Single or double adjustable, I'm still undecided on this one, though I am sure as I do more track days I would appreciate/desire independent compression and rebound adjustability
6. I want to lower the car about an 1" and I also want to corner weight.
7. I do NOT want true coilovers!! After looking at my car from underneath, reading various posts and talking to a current racer in the Koni challenge series, there is no way I want to run that kind of coilover in the rear.

In order to put a percentage on my driving requirements they are;
70% commuting | 20% winding road corner thrashing | 10% track days
- - - my track day % will probably increase

Price point, I am willing to spend up to 2k. Now if the ideal set is somewhat over 2k, I will stretch, though I am not sure I will stretch to 3k

I have a set of hotchkis sways (still to be installed) that I will use in conjunction with whatever coilovers I decide upon.

All of my reading has netted me that Truechoice Koni's fit the above requirements but I have to assume there are other options.

Ok, time to step back and start reading your replies...

p.s. I hope this thread will help others with similar requirements as me...
Just to add another option for you is the KTS/SPL setup. I've been running this setup for over a year now and find it great for both street and track.

1) It passes the fiance test so I assume it will pass the wife test also for ride quality on the street
2) It has proven a very capable track setup in the many trips i've taken to various road courses around Texas along with many 7k rpm launches at the drag strip
3) This is the only criteria that doesn't match. The rear shocks do need to be adjusted from the top
4) You can get this setup with linear Swift springs and order whatever spring rate you'd like.
5) Single adjustable
6) No problem with changing ride height
7) These are not true coilovers and actually replace the rear factory spring arm with a billet one with an integrated height adjustment perch. Plenty of camber and toe adjustment when used with their rear camber arm.
