I found a couple of road tests CAR and DRIVER did on the Probe,with some pretty good photos.
It looks like the stock car,in elevation,has about 41% aft-body and around 39% of 'Template.'
Length/Height = 3.453 which is very good for a production car.The ideal is 5.0.
The rear is kinda wide (it's a wedge form) so the wake is also wide,but flow very strong,and should provide nice flow onto the tail.
With an extra 24",your L/H will be 3.916 which exceeds many concept cars.
You're already sub-Cd 0.3, and with the new tail you should easily see in the 50mpg range.Sweet!
