Frank and Ed..
here is the engineering answer. We had a 5 minute window at 6pm with Raj, Chris, Larry and Bob on stage prior to dinner with approx. 797 brilliant engineering nerds in attendance. It was like herding cats. Indy, DBK , Blake etc. and all others were "in the building" but could not make it up to stage due to a series of Engineering discussions being conducted in the arena with Sparco, Multimatic, Brembo, paint suppliers etc. They were actually having these engineering discussionS partially to help certify that your two (2) vehicles would be built correctly.
We can fill you in on all the details in August.
Thanks again to Vince for posting.
