Sorry for the boldface type; I am not yelling.

I have just received my Techart suspension (noselift), the installation will be done at my Porsche dealer. What makes me nervous is the alignment process. I have contacted a lot of shops and found out that most of them did not have any previous experiences with Porsche cars.
I have read Cannga’s review for Bilstain PSS10 which is if not the best, one of the best reviews but I don’t know if I can use any of that info since it’s a different suspension.
<o></o>
I’m not installing any sway bars, just the front and rear coilovers with the noselift mechanism.
<o></o>
My questions are:<o></o>

If possible, **always** use Porsche familiar shop. You don't want a rookie touching your baby. You don't want people to be learning with your car.

<o></o>
I have 20” wheels will they affect the alignment?

No
<o></o>
What about cornering alignment? One of the shops I have visited said that when alignment is done cornering alignment comes to place. This does not sound very good to my ears.

Do you mean corner balancing? Basic alignment does not "include" corner balancing. Corner balancing is meant to make your car feel the same turning left or turning right -- us amateurs are not that good to feel such a difference . It is not necessary unless you are a purist and track the car. I don't have it.
<o></o>
Can someone give me the measurements needed for the complete alignment when dropping the car by 20mm? Or there is not such a possibility?

All you have to do is to tell the shop to install the set and drop the car 20mm from stock height. (I actually would recommend a more moderate 10-15mm to start out with btw.)
If you are looking for stock alignment numbers, they are all in that thread. Competent shops should know all these numbers.

My car is a Cab so i will never track it, i just want a good setup for street use.

There are two separate steps you are talking about:
1. Install the Techart and drop it a certain height.

2. Align the car.

This is your instruction to the shop:
1. Install Techart. Drop 20mm from stock height front and rear.
2. Align the car to stock alignment settings. (Basically it's better for you to keep the alignment same as stock for now. Play with it later as a SEPARATE step from the Techart installation.)
3. Keep all old parts. Test drive car.
<o></o>
Any information will be much appreciated, thank you in advance

I believe in changing your car one step at a time. Much more educational and less confusing, and, trust me, it will save you a lot of time in case something is not to your liking. That is why I think you should just install the Techart first, and keep the alignment setting same as stock for now.

Hope this helps. Alex of Sharkwerks here should know this system very well if you have any question.

Cannga, don't you think it would be better to do a GT2 alignment since i'll be using the GT2 height?

First, by looking at Alex's summary table on the last page of my Bilstein thread, you will see that reducing ride height 20 mm front and rear does NOT bring you to GT2's height. The front will be close but the rear will in fact be lower IIRC (check).

Second, I wouldn't worry too much about the GT2's ride height, alignment numbers, etc.. The goal is to find settings that are more sporty and allow you to take curves faster in the Turbo, not to duplicate GT2 numbers! GT2 is a significantly different car in one aspect, it is 2WD. This fact alone makes the setting for a Turbo necessarily different from the GT2.

Once you get to the alignment phase and read more about it (again, last few pages of the thread), you will find that alignment change is in fact pretty simple. We'll keep every number the same as stock, except for front camber and front toe. You will find that one setting for the Turbo, change front camber to a more negative setting, is similar to the GT2 setting. But it is so not because we are trying to duplicate GT2. It is so because negative front camber increases front tire's contact area in curves, reduces slip angle, and therefore reduces understeer, a major flaw of the stock Turbo alignment.
OTOH, a second alignment change, very slight front toe out, is one that benefits the Turbo's 4WD system and assisted steering greatly -- allows better "rotation" in curves and more direct steering response, but is not necessarily recommended for the 2WD GT2.

Always, keep in mind that you are doing 2 separate things here: first, install the Techart, second, change the alignment. And again, I would very strongly recommend that you do it in separate steps. This way, if the shop screws up the installation for whatever reason and the car doesn't feel right for whatever reason, it cannot be blamed on an alignment change.
It does not cost that much to separate the steps (US $200 each time -- the cost of alignment adjustment).

Lastly, is there some reason that you are not installing the Techart anti-sway bars?

Just to add a bit, you need to:
  1. install the noselift (or is it the full kit?)
  2. drop the car
  3. let it settle (may not be needed if doing noselift only)
  4. get an alignment
Even if you go back to stock alignment specs, you need to have an alignment with the drop. I can't argue with Cannga's thinking regarding doing incremental mods but lots of us do several things at once too. Whether it is due to timing, money, inconvenience, lack of patience, or some other factor, many people make several changes at once. You could start with a more aggressive alignment first and tweak it from there rather than going stock -> more aggressive -> further tweaks.

In addition to Cannga's excellent thread, this one has some great alignment info (with a fair bit of overlap):http://www.rennteam.com/forum/board/...x.html?vs=3#_2

The reason i don't get sway bars is because my car is a cab and i don't want it to become stiff and noisy,

thank you for the info

The installation will be done at my Porsche dealer who is also Techart supplier. The alignment will be at another place.

If i understand correctlly you are telling me to put on the suspension on the stock height, and then adjust the height. After that take the car to an alignment shop.

Is it a good idea to change tires too?

This sounds good. Any reason why you don't want the alignment done at the Porsche dealer also?

No. Install suspension and drop height AT THE SAME TIME. Actually, you cannot install the Techart/Bilstein at stock height (there is a reason for this but I don't want to confuse the issue further). Do alignment later.

Is it a good idea to change tires too?

Only no in the sense that if you want to learn from this and make the process fun, then you change one parameter at a time. In other words, do the tires later unless they are all worn out and need to be changed immediately.

They don't have the equipment to do the alignment there
