I can tell you why my cars ride height has ended up where it is. I have ATR adjustable shock absorbers and springs. The front height is set to get the track rods horizontal. Although my car is a 2013 one it has the later (post 2014) front uprights with the raised steering arm position, so the front ends up at about 6" The rear shock absorber lower spring seat on the LH shock comes close to the drive belt, it's adjustment is set to have a small clearance. With this spring seat position the ride at the rear comes out at about 7.5". Much of my driving is done with a passenger and then it all runs fairly level, the front hardly moving. I prefer the extra ground clearance the ATR's give for touring, you don't ground out on humps and kerbs.
I think Dab of oppo is running the Spax shocks that do allow for a lower ride height. He may also be running the original front uprights with lower steering arm position and no "comfort kit". The track rods will be about horizontal with that set up when the ride height is 4". The rear Spax have the adjustment to run equally low and the standard non adjustable ones tend to sag over time down to about that ride height.
