The 911R that set the World Endurance Record would be an interesting build. The car was required to carry on board all the spare parts it intended to need. Porsche did several things to lighten the "R" including a fiberglass hood, you can see it deflecting in the photo from the aerodynamic load.

I have an early 911 project planned but it's not the BP sponsored car.
