That is something that the other local Porsche pro tuner shop can do when they corner balance my car (set left & right shocks to the same length if necessary) -- that would be all part of their process of corner balancing the car right?

Yes it will be part of their process. If you like doing things yourself, you can set it up before you get to their scales and save yourself some labor time. I'm guessing a porsche shop charges 100+ per hour for labor.

Yea, anywhere from $90 to $100/hr , so you are right. My Z was a PITA to jack up the way it was let alone being an inch lower now. Not sure how easy easy that it to do. Is there another thread that has "How To" step-by-step instructions for doing that?

Although, perhaps good timing as I just got TEIN Flex coilovers installed yesterday and asked my mechanic to lower the ride height an inch (to start). I have a 2003 Track Ed. 350Z that I got used to run out on the track for Driver Ed. events. I still drive my Z on the street but I suspect in 3 to 5 years it will become a dedicated track car. Until then I'm looking for a setting like three_fitty, something agressive but functional for the street (i.e. speed bumps, etc.) but a decent starting point for the track.

My mechanic said that my stock ride height was all over the place. Is that normal? He said that he "leveled" the front and rear respectively and then lowered it an inch front & rear. He said that my front sits an inch lower than the rear. Does that seem right? I don't know much about this stuff yet, but that doesn't seem right to me(?). He said to try it out on the track and adjust from there (either to lower the rear another inch to equal the front or raise the front an inch to match the rear). Today it gets aligned at my local STS tire center. They are going to adjust all those other settings given the new ride height and set my camber to -2.0 front and -1.5 rear. Its agressive for the street, but that setting feels good to me out on the track. Unfortunately, that STS doesn't have scales and can't corner balance my Z, so I will need to take it to a local Porsche performance shop that can do that.

three_fitty, what did you decide on?

Thanks.
I'd have to find some level ground to remeasure. I'm guessing around 1.5" in the front, and 1.3 in the back. I will have some measurments for you guys tonight. Pretty much one finger gap in the rear, and as for the front, the top of my tire sits right below the front fender (no gap). Looks hot! and it doesn't bottom out.

I did measure things out... it seemed fine. But when i put the car back down, it was really really low. I had the front tire tucked in about 3/4". Do you happen to know how far it is before you hit the bumpstops?
