Welcome to the forum!
Just a heads-up..we try to maintain a Safe-For-Work environment outside of our Off Topic forum, for those that may be viewing in the workplace or in a family environment. I've edited your post with the videos, since their soundtracks are a little out of "Rated PG" range.
If you need to post up something like that, please do so in Off Topic, and put a warning that it's NSFW. You should probably also know that promotion of street-racing is also frowned-upon around here.
Thanks for your cooperation!
