I just checked those clips. That Tiburon was a new guy who I hadn't seen at the track before. They probably hit their brakes hard turning into turn 3 which is what I tell new guys never to do. The 2nd one was Chris and Al pushing as hard as they could to win. Those are two of the big dogs and have a rivalry going. Contact is always possible but not common though. That's just what gets put on youtube because it's more exciting to the audience who just wants to see crashes.

we used to have roundy round drags on my old local track...its cool..i seen alot of cars get smashed..it better be a beater or car just for that..because i seen more then one get totaled out..

a s10 used to dom our..it was set up perfect..bed was just sheet metal outer skin and such..had a strong motor and like a 4.88 gear..outside control arm was longer then the inside an such an ran on racing slicks..fucker was damn fast
