Try this : http://www.racedepartment.com/threads/halfords-staff-christmas-go-karting-trophy.97763/ These are Karts (ISI) with gears (downloaded on RaceDepartment) : I've tried it on Euroring and I got a lot of fun!
We did an evening of 5 minute races with these cars and it was so much fun. My face was hurting from smiling and giggling. Once you finish a race you can do donuts till the engine catches fire. Guys were flipping 10 feet in the air. Oh so much fun.
