This is what i got from my dealer today regarding the rule changes for the 04 season: MAJOR RULE CHANGES 2004 Regulations will be mailed to all competitors in the next two weeks. There are few major changes from 2003, but you should be aware that: 1) You may now choose to sign up on a race-by-race basis, or for the entire Challenge season (at a reduced fee). 2) You no longer have to be the owner of the Ferrari you race. You may rent a properly prepared 360 Challenge for your use, or you may rent your car to another driver. In any case you must still have a 2004 GrandAm drivers license and be properly registered for the Challenge. Professional drivers -- as defined by the Regulations and the Challenge Manager -- remain ineligible for the Challenge. 3) A HANS device in mandatory for all drivers.
