We've known you for a few years already and your madness only keeps growing, I think I am a t-shirt or sth. compared to you, but here we go, the better half saw me marking the floor and measuring the width and booked time at the shrink again, this is starting to be an expensive hobby.

GT2 Cd 0.34 front area 2.04 CdA 0.694
I always thought there is an error in this drag quoted number by Bongers and still do. I am convinced that the GT2 has more Area, more
drag, and more downforce than the stock 993TT.
The measurements are as follows on my car:
Width at the edge of the weels: 1960 mm
Width at the edge of the flares: 1990 mm approx.
Width at the edge of the weels: 1790mm
Width at the edge of the flares: 1850mm approx.
As to the front flares appearance (gap with the tires), on my car, some of it is due to camber
Measured the same way, my stock 993TT is:
Width at the edge of the weels: 1780mm
Width at the edge of the flares: 1800mm approx.
Width at the edge of the weels: 1640 mm
Width at the edge of the flares: 1650 mm approx.
