Sauce on last picture is Roadkill. It wasn't their best one, but it was pretty good. they basically do dumb **** with classic junk. the subaru shootout was my personal favorite.
Burnouts are often done in drag races... It heats the tires up, so the car sticks better to the surface of the race track and also lays small layer of rubber under the starting position, which helps to increasing traction and improving launch conditions.
