You can race a bone stock car like a lot of other people do, all you need is a valid drivers license, a helmet (loaners are available), and a car that passes a safety inspection. Battery must be secure, wheels and tires in good shape, seatbelts good, brake pedal firm, all loose objects removed from the car. For more info see these local sites
