Excessive braking is a universal rule, I would doubt any track would say they allow it. Some tracks have their own set of rules, such as a visible tail light, courtesy staging, no beer in the pits, and the like. There are 4 IHRA tracks in KY, Beacon, I-64, London and Clay City. Go on their website or call them to see if they have any rules in particular. I tend to stay North of the Ohio river, as some of those tracks still have single Armco guardrails and the tech inspection consists of handing in your tech card to a teenage girl in the tower.
