General car info and calculators

[admin]

I thought it would be a good idea to make a thread for links to general car info. I dont see this here really but on other forums I feel there are alot of opinions rather than facts. I though this thread would help with the general mechanical knowledge along with useful conversions and anything else that is relevant. Ill start with a few. Post any useful links you know of.
