So is your new rollcage going to be on-center like in the renders? What will you be using for glazing?
Since you're cutting off the old glasshouse, you're starting with a cleaner slate than most of us get to. Lucky you. I look forward to seeing some pics and data.

I goofed a bit.
In "TUNNELING THROUGH THE AGES" by Alex Tremulis,Road & Track,August,1982, Alex gives Jaray's cars a range of Cd 0.24-28.
One car tested in 1922 By Wolfgang Klemperer registered 0.28."Experts" of the day scoffed at the claim.
Later in 1939,the same car was re-tested in a more modern tunnel and scored Cd 0.245.I believe this is the value for the car that MetroMPG posted.
Jaray's teardrop body of revolution on 4-wheels scored Cd 0.13 ( 1922 ).
