Uh street racing is illegal and you can get killed or kill someone else. An SCCA license costs $3k or so, Auto Xing doesn't need a license. I'd rather pay $3k and drive legally and safely pushing a car to its limits rather than street race and end up dead or in jail. Just because you have a fast car doesn't mean you need to push it, laws are made for a reason and if you don't obey them then you should be prepared for the consequences.
