I think he is referring to a bracket racing class for sportsman (foot brake) imports.

We helped start a Corvette challenge race at BMP. It is a bracket event for foot brake cars, corvettes only in this case. The races are the 3rd Sat of the month and there is no payouts to keep the cost down and participation up. It's for points and bragging rights. It's really something you all should try. Fastest car doesn't garauntee a win, it takes driving skill and being very familiar with your car.
