Trying to determine what general ride height my car is setup as with PSS9's and 18" OEM wheels relative to Stock USA turbo, ROW Turbo, GT2. It was this way when I bought it.

From the ground to bottom of fender lip, I'm sitting at 25 1/4 to 25 1/2" on front and rear. Does anyone have a feel for what this translates to?

I will try and get a measurement from the method described in the tech manual bolt heads later this week if the sun comes out!

For the rear, the manual says: "Measure from wheel contact surface to the locating bore in the rear−axle side section (between toe and camber eccentrics)!" Is the measurement taken between these two holes on the flat metal surface or at the bottom(closest to ground) of the raised hole. Can't quite tell from photo.

Thanks.

My car has PSS9's, so I may be able to help. However, PSS9's are adjustable (every car could be slightly different), and I'm not really sure what you're ultimately trying to understand. Do you just want to know how much lower the car is compared to stock and other variants (ROW, X73, etc)?

Yes I'm trying to understand where the car is in relation to USA TT, ROW TT or GT2 ride height. Car was lowered on PSS9's when I got it, and have some concern about the height based on some threads regarding PSS9 issues when lowered to far.

Thanks.

Ok I took some measurements using the Tech Manual measuring points and here's what I found:
___________________***** Relative to *********
__________Current ___USATT ROWTT X73 GT2
Front _____114mm ____-44 __-24 __-14_ -4
____Fender 25 1/4"
Rear ______128mm____ -35 __-25___ -5 _-5
____Fender 25 1/4"

Bottom line is the car is set very low.

Not having problems that I'm aware of, but haven't really pushed it as yet or had track days. My concern is the discussions in the past about PSS9's not suitable for GT2 ride heights and running out of room, hitting bump stops.

I'm wondering how low I can really go without having issues with PSS9? Is the ROW a safe setting? Or maybe split the difference between ROW and X73.

Thoughts?

Okay... From the floor to edge of fender lip (through center of wheel).

Front = 25 3/8
Rear = 25 1/2

I've never had an issue with rubbing or hitting bump stops at the track with this height. FWIW, I've also corner weighted the car and left to right is about as perfect as you can get. From front to rear it is what it is. My suspension has also been on for a few years at this same height. Initial settling, of course. Not that it should matter much, but the above measurement is with the car running it's winter shoes. Blizzack 225/40 18 and 265/35 18.

Hope this helps...
