Hell, I would employ the services of a wind tunnel. Half-day sessions can be rented for only a couple/few thousand. Cheap speed as far as I'm concerned.
Looking great, Tony. Really excited to see her getting there.
What do you plan on doing for data acquisition? Don't skimp on sensors or on the engineer to interpret said sensors. I'm sure the Vision boys will not let you get on track without the full gamut anyway. You'll be flying blind otherwise.

I'm trying not to.
I looks like we'll probably only have to widen the rear (which is already a wide body). The rear tire will be a 330
I'll know today if I can fit the 300 Michelin Blue Slick under the front w/o having to widen it/flare it.

All of the above. Looking at the flares and the side skirts of the Caddy as a template.
The car is going to get flat bottomed from the engine cross member back to the rear suspension cross brace, then to a difusser. The exhaust will exit through the center of the difusser.
Dwain is talking about venting the front wheel wells. No mention about the rears yet.
So now it's wheel and body time....

The wheels and tyres alone will cost as much, if not more than many guys buy their 951s for in the US!

Makes me wonder if I can fit the 710s. Not entirely sure of the total advantages of the extra diameter but seems like the Michelins are the favoured rubber. The Blues being what the Cups run. I think it's track dependent too.

And in testing used (6 heat cycles) Michelin Blues were about 2 seconds a lap faster than new Yokohama slicks on the same car, same day, same track (AutoClub Speedway in Fontana... the Roval config).
The big issue with using a tall drive tire whether it's a 690 or 710 is gearing.
I'm installing the short 951 5th gear into my S2 boxes because of this. But that won't help my 3/4 gearing. I'll probably have to end up using custom gears because of this.

Pat, the larger diameter also means a bigger footprint so there is more rubber against the tarmac (which equals more grip given the the right compound)

Update....
The car is still at Vision, but the only thing to do is the rear blade sway bar, mounting the sway bar adjuster, and the associated hardware/cables.
The window net, fire suppression, front suspension, seat belts, and windshield are done.
I ordered two sets of Forgeline GA3R center lock version wheels today (ouch).
See them here:
http://www.forgeline.com/products/co...ries/ga3r.html
Until these come, Vision can't do the body work. So they are going to finish the sway bars and the car is leaving to get wired and tuned with the larger (much) exhaust system.
Then it's back to Vision for the body work (widening the wide body and some other stuff), then paint, and it's off to the track.
There is light at the end of the tunnel....
