Brief run down on the classes.
Tuesday nights Gamblers race. Bascially anything goes. Bracket racing on a .500 sportsman tree. Bad thing is that there are dragsters running electronics. Very tough.
Index 12.0 , 10, and 8.50 check the schedule. I believe about 6 times a year. Run off a .500 pro tree. 2 runs to qualify then a ladder starting with the top 8, 16, or 32 depending on the number of entries. Very competitive and you better be able to run on the index. I ran the 12.0 a few years back. I ran 12.04 and qualified number 4 of 8 in a 15 car field and the slowest car to qualify was 12.07. Trans brakes are allowed but no electronics. Bacically bracket racing on a hard dial in number (every one in the class is dialed the same example 12.0)
Summit ET Series. About 21 races a season (see schedule). This is the most popular. 3 classes on a .500 sportsman tree. Street, PRO, and Super PRO. Your pay $50 or so in the beginning of the season and the track keeps track of points. Top finishers get to represent ATCO at the division ET finials race in September. Big thing for bracket racers. Street class is 19.99 – 11.50, mufflers, and dot tires, factory glass. No electronics or dragsters. Check rules or call track. Next class up is PRO, no electronics or transbrakes, no dragsters. 15.99-9.0. This is more a true race car class. Slicks, open exhaust, plexyglass windows etc. Last class is Super Pro, electronics and transbrakes allowed. 12.99 – 7.0 Dragster class with some fast door cars. There is a entry fee for all classes.
I would recommend that you run Street next season. Atco is very very competitive. Check the rules on the site and or call the track. I would also recommend you go and watch a few times to get a feel of what’s going on.
