http://www.racing-database.tk
I´ve found this page today,it has a lot of information about results of the most important racing competitions,since F1 to Karting,including F3000,CART,F3 in many countries,Touring....during the last 10-15 years....the F1 since 1934.
It´s amazing,at the same time there are drivers profiles with stats of many drivers....
,it has it all,but one problem the page is in Spanish,it has some things in english,and the webmaster told me he will translate it in the near future with updates every week.
It worth the visit.
