Dude the slope is immense....its probably about a 12 to 5 pitch maybe I am just guessing, I know its a pain just to walk up, hell we had trouble getting my ZX3 with the eibach kit up there...on the other hand it would cost TOO much money for greg to try and level it out or something of that nature...Mad props to the riendeer master!!!!!!!!!!!!
I think he would scrape if not completely crash if he tryed going in staight, that angle is probably the only way of doing it without destroying the car. This is similar to the reason why off-road 4x4s go over trenches one wheel at a time. ie- less chance of bottoming out or hanging on a bumper
