2010 LaCrosse Fairgrounds Speedway Rulebook (PDF)

NASCAR LATE MODEL: The NASCAR Late Models are the top division at the speedway. These cars race weekly for track points, and for the NASCAR Whelen All-American Series National and State Championship standings. The cars are build for racing "ground-up" with the exception of engine components that must remain stock from the automobile manufacturer. Body styles used are from approved domestic made cars, 1992 or newer. They race on 10-inch wide slick race tires and may either use high-octane race fuel, or regular pump gasoline.

GRAND NATIONAL SPORTSMEN: The Sportsmen cars are the "middle" division at the speedway. They run on the 5/8th mile track, and begin as street-legal cars of the 80's and 90's. The frame must be factory stock produced for that make, and the car weighs a minimum of 3200 pounds. Tires used are an 8-inch wide treaded race tire, and they may use the same fuel as the Late Models.

THUNDERSTOX: The Thunderstox cars are full-bodied strictly stock class, including a stock engine. Only a few modifications are made for safety to the cars. These cars race on a smaller, inner oval - a quarter mile track. All of these cars were at one time used as street cars in the 1980's and 1990's. A minimum weight is 3400 pounds and they race on regular street tires.

HORNETS: The Hornets are the Speedway's entry level division, which race about once a month. These cars are typical 4-cylinder small cars seen on the streets in the 1980's, 1990's and even the 2000's. This division is for fun, and the easiest way for someone to try their hand at racing. The cars are strictly stock from the street.... most of the interior is gutted out, a roll bar is added, a few other safety modifications, and it's ready to race.

R.A.Y.S.: The R.A.Y.S. are one of the speedway's newest divisions. Introduced at the Oktoberfest Race Weekend, the R.A.Y.S. stands for "Race All Your Stuff", which may be also known as "Run what ya brung" at other tracks. There are very few restrictions on these cars - it's a battle of horsepower on the quarter mile track. Check out the event schedule to see when you can see them battle it out.

SKIDDERS: The Skidders divison is similar to the hornets, with the exception of the rear wheels. The rear wheels do not have tires; instead they have plates welded on to slide around, as if they were racing on dirt. It's a wild and crazy fun race for both the fans as well as the racers. These cars can be seen from time to time as a "novelty" event, as well as at events like the Smash O Rama and the Eve of Destruction.
