2010 Rules ILLINOIS VINTAGE RACING
As Illinois Vintage Racing grows and expands every effort is being made to revise the rules to stabilize car owner costs and ensure that everyone is competitive. The 2010 rules are designed to protect owners from getting too eager to outspend other competitors and to maintain overall competition. The club has an impressive group of cars with several new entries being built for the 2010 season. The quality and professionalism of all of our club cars is absolutely amazing. The club needs to maintain rigid and tough standards so IVR can attract additional club members who have been driven out of racing because of the high cost of tires, exotic chassis and expensive engines. If club members hunt diligently enough, vintage cars can be located that are just waiting for restoration.If club organizers strive to keep all cars on a level playing field, participants will have a great time and generate memories to share with fellow club members, fans and family. The rules provide owners who want to purchase vintage cars or who already have older cars an equal chance to win a race and continue to be competitive.
We have made several rule changes for 2010 to maintain our "Vintage" image and not become an updated version of Late Model or Modified cars which run at weekly shows. * Denotes change from last year

GENERAL EVENT INFORMATION
The winner of any heat race, trophy dash or feature at one event will automatically start in the rear of the field at the next event. This will give more competitors a chance at carrying the checkered flag and sharing in the enjoyment of a successful racing season. The overall philosophy of IVR is to maintain close competition, reduce expenses, avoid "high tech" cars of the modern configuration and most of all enjoy the racing of yesteryear.
