Hi, fellas. Here's an obscure one for you. 
I've searched the Net in general and TNF in particular for info on claiming races in auto sports competition. Precious little out there. The only thing I could find was the following link:

I find this concept most intriguing and would hope that members could contribute some things they've learned over the years. Some of the details which I'd like to learn include...
started when? last invoked? classes involved? locales?
TY.
Claiming classes were quite common in short track racing throughout the U.S. (and Canada) and still exist in modified form to this day. I have no idea when/where it first appeared. While doing research recently I turned up a claiming rule for the "Junk Car Derby" races at Colton, California in 1940 (actually, these cars were more early versions of the post-WWII Track Roadsters). Any car was eligible, with the stipulation that it "must not be valued at more than $100."
As has been mentioned, the class was usually for a low cost, entry level Stock Car class (Claimers, $99 Claimers, Jalopy, etc.), though IMCA Modifieds have had an engine claim since they began.
There have been quite a few variations on claiming rules, prompted (as so often is the case) by abuses. I recall one short track where drivers battling for the points championship kept claiming each other's cars as well as other contenders, so the association put limits into the number of claims one individual could make. Then friends of each driver kept making claims which got so out of hand it led to an emergency meeting and new rules.
Many Northern California tracks (as well as Carson City, NV) had a $99 Claimer class into the 70's. As Jim mentions, in the late 50's/early 60's, much of Southern California's Stock Car racing used claiming rules. But, as cars got more and more sophisticated at places like Saugus and Cajon, that went away.
Some have speculated that IMCA's engine claim rule led to a more diverse array of powerplants. I don't know IMCA's current engine claim rule, as it has been fine tuned over the years, but at one time refusing a claim led to a loss of all points.
