If you have never been to Rockford Speedway Bahamas Brackets race you are missing out. Cars will qualify a set time and they can not run more than .2 faster on the weekend. They'll be 4 v8 brackets and 2 4 banger brackets. If you are in a slow bracket and break out you move up to the next faster bracket and that lap you broke out with is your new time.
This format creates extremely tight lap after lap racing. Add that with the fact you'll see dirt late models racing against pavement cars it is an AWESOME show. Dress warm, come out and enjoy the show. It'll be a top 5 on your yearly list.
