ride height change... H&R coil-overs
Here's a before and after of my ride height from generally the same angle. Took her out for a spirited drive this afternoon up through some canyons near my home... WOW, what a difference. As they say, it was like she was on rails.

Jeff,
The new stance looks perfect! Are the H&R coilovers adjustable, or fixed position? Please bear with me as I learn the ins & outs of 993 "safety modifications"...

No problem Andreas... they are adjustable in the sense that they are threaded so they will lower the car anywhere from 1"-2" (mine came down a little over an inch). They are not adjustable after installation like the PSS9's are... I didn't need this as I don't need to "dial-in" my ride height for changing situations (i.e., track vs. street).
I had mine set at just below ROW (rest-of-world) ride height. I am about 25-1/4" from ground to fender lip all around.

Excellent. That answers my question. Is there a preferred vendor for these, or are they commonly available? Also, do you know who manufactures the actual struts, as I presume H&R just makes the actual springs?

Jeff,
They aren't HD's. The Bilsteins on the full H&R coilover kit are fully threaded shock bodies. They also probably have firmer valving than HD's as well.

Jeff,
If the shock bodies are threaded (for height adjustment) why does the H&R setup not allow for on-car adjustments? Is it simply that the collars are not machined to accept a coilover 'wrench' or is there another reason I am missing?
As much as I like the PSS9 setup from a technical standpoint, ease of adjustability will not be a deciding factor when I first set up my (future) 993. I will certainly want to lower it slightly, but will stay with an ideal stance for quite some time.

Andreas,
The H&R's are height adjustable while on the car but they shocks have no other adjustments. The PSS9's are height adjustable and have dials with 9 different firmness settings that can be adjusted while they are installed on the car. Hope that helps.
Check out http://www.evoms.com/porsche%20ec%20art%20test.htm for a picture of what they are talking about. Go to the 993 section then click on the suspension option.

The H&R coilovers are Bilstein shocks valved to H&R specs and they come in a variety of flavors. What Jeff has is what I also have on my cabrio and its the basic H&R coilover. Which means Bilstein shocks valved to H&R specs with matching spring rates of 295lbs front and 360lbs rear which is approx 100lbs stiffer than the US spec Porsche suspension. They also come even stiffer in the sport coilover variety, then you can have even stiffer with the RSS coilover and finally H&R makes an adjustable ala PSS-9 coilover system which is called PCS.
What I really like about H&R is that their coilover systems seem to keep factory specs in terms of stifness differences between front and rear. That alone swayed my decision not to go with the PSS-9 , which besides back in 2001 it had some fitment problems, the spring rates front and rear difference was almost 400 lbs!
Like Jeff said, even the basic H&R coilover kit will transform your car to a fine handling machine. 3.1/2 years ago when I installed mine on the cabrio I was in awe with the transformation of the car especially on the track. The car felt neutral and very balanced especially having a shop do an awesome alignement and corner balance. I have not found the need on a street car to have an adjustable system and on the track pretty much my ideology is to run what you brung especially when not racing. I learned a great deal on the cabrio on track before I plunged for a dedicated race car and I attribute that to the fact that I had no suspension to play with and get confused ( like I am now) with what the car was doing. I simply run it hard and was able to improve my speed just by concentrating on driving. Surely the H&R coilover helped in the fact that it gave me a beautifully balanced car to learn on and I think that is what most of us are looking anyway...
