While that is impressive, now add everything the car needs to be a "Street" car at these events, AND drive it 1000+ miles. People think it's easy, but are humbled really quick when something simple can take you out of the event. This isn't a weekend bracket race, or heads up race, you can use you golf cart to push the car around the pits...
100% HAS to be the hardest/most challenging part of these events. I would never attempt to drive so many miles , too hard on parts. I will take being pushed/pulled around the pits any day , and im not too proud to admit it. Any one who thinks its easy.... you in for a rude awakening for sure !!! To answer the OP question.....i would build nothing, i wouldnt attempt this event
