You forgot one cut off, what if it was set at 40 years, then kept at 40? In 3 years the '68s are no longer allowed to race. How many people are racing anything made in '68 anyway? It gives anyone who's racing a really old car a chance to know the deadline is comming up without immeaditely being canned, any 71's have 5 years left and ect. This also keeps people looking for the newer car, and allows for performance creep. It'll also allow for things like SMG and drive by wire throttles. Maybe Vintage should pick up used IT cars as a source for car classes? After all how many pro cars are being built from street chassies? Isn't campagaining an IT car give it a peddigree? I'd say if it survives it does.Originally posted by Matt Rowe@Sep 21 2005, 09:57 PM
Looking at putting in a cutoff date for car eligibility I looked at the recent results from the MARRS labor day event. Based on the results adding a cutoff date would result in the following percent reduction in the field.
Cutoff 30 25 20 15
ITS 12% 18% 18% 53%
ITA 7% 20% 47% 87%
ITB 53% 65% 76% 100%
ITC 8% 69% 85% 100%
So you can see that even a 25 year cutoff immediately decimates the ITB and ITC fields. ITA would be cut in roughly half in five years. Overall it looks like a cutoff date would significantly including several top ten cars in each ITB and ITC with only a 25 year cutoff.
I don't think an arbitrary year cutoff makes any more sense than using stock horsepower and curb weights to class cars. This is only one data point but I hope the ITAC, CRB does a lot of research before they put o lot of cars out to pasture.
