Nice!
My car is 603 rim-fender, with no load in it; 18" rims. Stock (non-sport) height would be 612 with load in it, but I've got Xd top mounts in there.
So basically in switching from C5 to D7/8, your ride height didn't change. But you also installed the taller spring perches, which raised it up by the ~10mm. Good to know... I've got myself in a right mess over the ride height calcs!
Glad it's working well for you so far, though disappointed that small bumps do feel harsher...can't have it all, I suppose! When do you think you'll get the rear end done? I think that will make at least as much difference again!
