991.2 GT3 - Colours. Spec. Q+A. etc etc..
Discussion
I have no idea how you guys get on, my R is 170mm high I have no paint left on the Splitter.
My GT4 was a ***** again scrapes every where to a point I could not take it into car parks or most places !.
I use to shave the furry bits off with a razor :-)
the GT3 is lower and has these solid ducts, these are not the brake flowing ones, but 2 massive extra ducts which sit only 60mm high and are very wide !!!!
my rear fins are 75mm high at best off the floor.
So people saying they can go over ramps is mystifying unless I live where the ramps are MUCH bigger !!!! (but when I say much I mean you cannot get over a 65MM ramp !!!
No way can I drop the car down to 45mm clearance on those 2 big ducts !!!
I would get no where without Lift in this car but I have already scraped the rear fins.

Big swing from 110 to 127mm.
I wonder what oem should be.
Taffy, are you sure its 127mm at normal ride height on level ground...? That seems high....(unless you've pumped your tyres up to 4Bar.... I wonder what oem should be.
Centre of splitter to ground on mine is 112mm at standard ride height, 147mm with lift activated. (Mine's a CS car with PCCB, 3/4 tank of fuel, nobody in it, cold Mich P tyres at 1.9F, 2/2R)

I've just re-measured mine on my new 100% level power floated garage floor and it is 124mm in exact centre of front splitter..Measurement in the same spot with Front lift engaged is 158mm.Centre of splitter to ground on mine is 112mm at standard ride height, 147mm with lift activated.

I'm going to get mine checked and have a thorough geo sometime in the next couple of weeks..I'd be interested what Apolo's GT3 is since he's had it lowered for track work..
Maybe my OPC wrongly assumed that my long drive is full of potholes when in actual fact its billiard smooth asphalt..!
Mine is the exact same spec as yours although mine's on Dunlops whereas yours is on Michelins..Mine however spent the period of the Beast from the east safely inside my new garage when yours was slowly being compressed by 10ft of snow which might account for yours being lower than mine..;)

The PDK extra weight should drop it a bit ;-)I'm going to get mine checked and have a thorough geo sometime in the next couple of weeks..I'd be interested what Apolo's GT3 is since he's had it lowered for track work..

but it seems none of the cars are anywhere near spec, again be interested in Apolo's splitter height is now.
if some people are on 110mm already and asked for a 15mm drop that would be harsh on those ducts.

I cant imagine anyone has altered the ride height on your car during the PDI, it would throw all the corner weights out, but for it to be 12mm higher than mine (and others) is puzzling. It would suggest the spring platforms on your car are around 10 turns higher, can't see that myself.....and I also doubt the Dunlops give you an extra 12 mm of ride height.I'm going to get mine checked and have a thorough geo sometime in the next couple of weeks..I'd be interested what Apolo's GT3 is since he's had it lowered for track work..

The delta between chassis lift on and off on your car is 35mm, which seems correct.
I wouldn't be dropping the ride height below std by the way, mine already scrapes the front brake ducts on a few heavy compressions around here. When you drop the ride height that much, you just lose too much compliance

Here's a suggestion for you Taffy, go and measure how many threads are visible on the bottom of your damper body - it's visible through the wheel above the brake disc. I've got 4 full threads visible. Assuming a thread pitch of 1.25mm, if I wound the platforms down as far as they'd go, I'd only get a reduction in ride height of around 5mm (the relationship of damper to ride height isn't quite 1:1). I'm not convinced that anyone has been able to drop the ride height by 15mm (from a splitter height from ground of 112mm)I'm going to get mine checked and have a thorough geo sometime in the next couple of weeks..I'd be interested what Apolo's GT3 is since he's had it lowered for track work..

If your splitter height is 127mm, then I'd expect you to have around 16 full threads showing on your front damper body.....

Its actually 124mm as i mentioned..I'm now starting to develop some self doubt in my measuring method..Am i doing it like everyone else i wonder..?If your splitter height is 127mm, then I'd expect you to have around 16 full threads showing on your front damper body.....
To clarify, my measurement is taken in exactly the middle of the front splitter aligned with a vertical mark just above on the lower bumper..I hold my finger against the bottom of the black consumable edge and measure level with the bottom of this edge..
It makes sense as mine hasn't come close to grounding even without engaging lift where my old GT4 would scrape..
First thing tomorrow i'll count the threads as you suggested to set my mind at ease..
Wearing my normally infallible conspiracy hat i'm starting to wonder whether when PDI'ing my GT3 they simply forgot to lower my GT3 from the higher transport height..

I always felt the ride height was bit to high at stock. Even with lowering 15mm at the front at 11mm at the back. Not a problem with bottoming on road use. But do use the lift a lot. Will measure and revert. A few of my friends also run this set up. They have not mentioned any problem's.
