Cars

I need a link that explains it simply. Also if you have some good details on stripping the windows, fuel tank and other things for stock car racing. No additions can be made to the car.

First you need to get a rule book from your local track or sanctioning body which will explain what they expect for a (aka what’s a legal) roll cage. It differs all over the country. The best sources are usually local vs. internet because you can build to your track instead of building a generic roll cage. You can also get a lot of info and help from the people who run the track – they’re usually pretty knowledgeable about who to talk to and what to do, and they’re happy to help because then they don’t have to turn you away for an illegal chassy.

I’d like to know the name of some of the best movie about car racing, the one with high critical reception, thanks.

Well, there are tons of great car films, but not too many good racing films.

Best one to come to my head is Days of Thunder (1990).

There are of course otheres such as:
The Fast and the Furious[s]
Talledaga Nights: The Ballad of Ricky Bobby (2006)
Cars (2006)
The Great Race (1965)
The Love Bug (1968)
Speed Racer (2008)
Death Race 2000 (1975)
Driven (2001)
