Is that with the stock windscreen, or racing screens?  My mirrors probably
add another 0.1.

Same problem, the car can be reconfigured for measurable changes in Cd.
Spats, tonneau cover, etc.  I believe tires start playing a role in overall
drag at higher speeds as well and of course several different tires were
supplied.

Sure, I'd like a copy.
