Like posted before, I'm lower than ROW RS height, so I just got the uprights in. Have yet to get the front aligned and will let you know on the improvement. i am sure it'll be substantial, or at the very least notable. Saw where original tie-rods sat and knew the uprights and tie-rods would have correct geometry. Can't wait :-)
Sunset for the uprights,tie-rods & bearings for about 1350.00, Done! Just do it!

I'm at the bottom of my PSS10 at the front and I'm running Rennline camber plates, I'm about 6mm away from GT2/RSR ride height. Remember if you want to run Euro or Euro RS ride height on any 993 the proper way of doing it is replacing the North American uprights/tie-rods and replacing them with Euro uprights and matching ti-rods at the same time with PSS10 coil overs otherwise its a waist of $ and effort and you'll never get the car to ride properly unless of course if your 993 is a European factory car.
Compare the 993 PNA parts list with the Euro parts list and you'll see what I'm saying.

Good call Ronnie on the new suspension. I went through the same dilemma as you, and I guarantee you'll love the PSS10s and have no regrets. SUV ride height just looks wrong on 993s.
Be sure to post pics when it's all done.

Hello guys, jumping in... My ride height is lower than stock but higher than OverBoosted28, I don't really know at where it is, but I like it. I am also thinking about going with PSS10s. Usually I prefer the car to be stock but I don't see upgrading the suspension as molesting the originality of the car. Specially when it is done to a standard that is the most consensual upgrade I ever encounter to a 993T (PSS9s or 10s). I believe my suspension to be the original M030, but altered somehow to be lower. I am a little lost in regard to the uprights and tie-rods. I only need to upgrade them if I go to Euro spec height? And then, should I get the Euro spec uprights and tie rods or the Gt2? If upgrade the upright and tie rods, Can I still ride it at above euro spec height? What would be the difference? Is there anything else that should be changed? I am thinking that if go with the PSS 10s, then I should do it the best way possible to explore the full potential of the equipment installed. Besides the ride height, my 97 993T is completely stock.

Upgrading to RS/GT2 tie rods + uprights is typically done when your at RS height or lower to remove bump steer and improve steering precision. Based on your details I don't think you'll be setup this aggressive.
The only other item you should look into when upgrading to PSS10s is the front control arm bushings. These are known to wear out too, choices are either Walrod Bushings (buy from FD Motorsport) or Elephant racing (RS style bushings).
Here is some reading you may find helpful to understand tie rods, bumpsteer etc:

As Knight stated, you may not need (or gain anything) from RS uprights/tie-rods. If you are not low enough, putting these on your car may actually induce "bumpsteer". Do as he stated, make sure front LCA bushings are fresh/Walrods or Elephant. "Pin" your existing tie-rods if they're in good shape and do the PSS10. The change in uprights come into play when ride height has your tie-rods not sitting parallel to your LCA's. When you lower it too much for the design of the standard wheel carrier/upright, the tie-rod sits higher than it should in relation to the suspension. With the tie-rod not sitting in a neutral position, it basically has "preloaded" it's effect on steering, thus you get "bumpsteer". This is my perception of how it works and what it is. I may be wrong, so others are more than welcome to correct or clarify this. :-)
I won't get offended, I'll just learn something :-)

Thank you for the reading Knight. I certainly understand it better now. I don’t think I'll go for an aggressive setup (I don’t track my car). I will measure the current height to see where I am standing, then I'll figure out what I need to keep it at the same current height, since changing to RS uprights and tie-rods, but keeping it high will probably result in bump steer anyway as OverBoosted28 said.
