Turbo-Gt2 road clearance?
Wow .... where are those Table 10 ride height numbers taken from? .... top of fender? ..... I always heard using body parts as reference point was less than accurate.
I have a chart that uses the front and rear suspension points as measures (Porsche AG data) for all models ..... the GT2 was the only difference, she used a dif rear measure point.
On Turbo .... there are dif numbers for U.S., ROW, and X73.
GT3 lower than all.

Lets see.
Front's that bolt head ... rear is that flat spot on the rear subframe, by flat spot I mean the locating bore, rear axle side section between the toe & camber eccentrics.
And back on the front .....the lower edge of that hex-head bolt of the tension strut screw connection to body.
I'm going to the dealer in next couple days to take some pics of the 997.2 underside to see if those points are still clear ... or any dif to 996 ... as we are re-doing the suspension on this 09 (still at the dealer) ... I'll take some pics.
Anyway ... measure assumes close to perfect level floor .... and an example for ROW Turbo is ... 138mm (plus or minus 10) in the front .... 148mm (plus or minus 10) in the rear.
This example gives a rake differential front to rear of 10mm ... and makes the front 20mm lower than the U.S. OE Turbo ... and rear 10mm lower than U.S. OE Turbo.
Example .... GTS is 46mm & 33mm F/R lower than U.S. OE Turbo with a 13mm differential (lower front).
Kinda neat ...... I've been trying to find specs for 997.2 .... but in absence of those we plan to just take reg PASM 10mm down another 15-20 all around with Bilstein Damptronics, see how she looks, corner bal, align and see how she goes.
Hope this helps.

Thank you for your info...they are helpful...And also you are the first to say the ramp in mm(10mm).in other threads I read about ramp in degrees of angle (1degree)that tend me to calculate tangent of 1degree with a wheelbase of 235mm in order to get the height difference from front to rear...Calculating so returned to 40mm height difference from front to rear...which is not ok...
Well ... I've always thought the front to rear differential was the easiest way to talk about that .... both those numbers can be quantified so....
BTW .... if you track your cars, front-to-rear height does have some effect on handling (of a well tuned-sorted-tracked car). I honestly can't say I have ever felt it but I've hear it from people more knowledgable than I.
Common thought probably is, just appearance .... and at daily drive speed that's no-doubt, that's true.
Good luck.
