The following two videos show you two world record attempts for most simultaneous donuts. Both British and Australian teams tried to set the record. The Brits tried it in 2008, which set a record of 29 Skylines, Evos and a Caterham doing donuts together.
The second video shows a group of cars in Australia trying the exact same thing with a total of 57 cars. They hold the new Guinness Book world record most simultaneous donuts.
