Here below two behind the scenes clips for Final Destination 4. Both clips come from the set of the Mobile International Speedway, which is called the mc'kinley speedway in the movie (like the name that kept appearing in the third film).

Stunt with a car crash - Final Destination 4
I've never been to a racing competition, but those behind the scenes of Final Destination 4 make me want to give it a try somehow, just to better appreciate the movie when it will be out in August 2009.
