I recently got my daughter started at the age of 3.. We spent countless hours in parking lots before ever hitting the track. I have a restrictor in the carb. as well as a throttle stop for safety. We are not the fastest ones on the track but we are learning to run good smooth lines and getting "seat time" . A friend of ours did a website for her, feel free to check it out and sign the guest book and let us know what you think..

Good luck to all..
