I remember seeing an article about Robby Gordon's Baja 1000 race truck and it had 7 feet of suspension travel in the rear. The shocks looked like race versions of something that came off a 747 landing gear.
Stadium Super Trucks is literally one of the best racing series there is. The action is non stop, reverse grid qualifying, jumping all over the damn place on amazing tracks the world over, 2 wheel driving in the competition cautions. Whats not to love?!
