They will never do it this way BUT here is my $.02 worth.
January each driver gets 36 cars delivered from the associated manufacturer of them. They are stock vehicles with the biggest motor that each manufacturer has for their vehicles. Front or rear drive does not matter. Car weight can not exceed a certain amount.
By Daytona the different teams must have at least 5 cars ready to drive in the first 5 races. Each car must have a reinforced roll cage but can have all interior stripped out to make room for roll cage, etc...Basically they should go back to what made the sport...what wins on Sunday; sells on Monday!
