Sum,
I have used membership forms for the following year before with no problems. Might want to check with Treasurer/Membership Tonya Turk, tturk@ecta-lsr.com.
Believe you are thinking running time only with the GMC. Under 135 not much required, convertibles and plastic bodied cars not included [additional requirements]. Once a car exceeds a 5 MPH cushion it will not be allowed to run again until it is in full compliance with competition rules. 135 MPH and over, all vehicles must conform to the safety requirements for the speed intended. 135-150 4 point bar, 150-175 6 point bar, over 175 full cage probably the biggest issues for you to be thinking about first. Best to get details for your intentions from Joe Timney, jtimney@ecta-lsr.com. This information taken from the 2007 rule book. Joe might take a bit in getting back to you, he and Donna should be catching up on their "real life" about now.
I know you understand Sum, but for others who might have ideas: anything over the 5 MPH cushion and you WILL be asked to leave, too far over and it is in not so polite terms with return priviledges denied, this from personal observation. Friendly, relaxed organization but when it comes to safety they get serious in a hurry, want you to have fun safely and be able to return for more.
Hope everthing works out so I can get to meet you in the Spring.
