Regular Divisions

Affordable Tire and Service Center Pro Late Models:

The Pro Late Models are one of the two premiere divisions at the Owosso Speedway. A unique variety of different made for racing machines can and do race together very competitively in this division. These cars are designed for the track with full tubular frames and primarily made for racing parts and pieces. The engines are cast iron blocks, but that is the only OEM part on the drive train in one of these rocket fast cars. You’ll find Outlaw (wedge) Bodies and Built Engines as well as Template Bodies (Similar to a NASCAR Sprint Cup or Nationwide Series Car) and Built Engines, or even the more economical “Crate” Engine under the hood. These cars will race around the 3/8’s (0.375) mile high-banked paved oval in the high 15 / low 16 second range and average over 100 mph. An average Pro Late Model team will have anywhere between $10-25,000 into their racing program.



The second of two premiere divisions at the Big “O” These cars are almost completely Modified (Hence the name) with the one exception of a factory production front clip frame from a 1960 or newer American Made passenger car. These cars have a stock front sub frame with a tubular “made for racing”  style center and rear section of the frame. With the sleek “outlaw” open wheel body on them, they travel the Owosso Speedway in the high 15 / low 16 second bracket and average over 100 mph. This division, first started in the state of Michigan in 1985, has evolved into one of the most popular divisions in the country with their unique body style and open cock pit design. They have always been one of the most exciting divisions to watch year in and year out.


Economy Print & Graphics Sportsman:

The Sportsman Division at Owosso Speedway features cars that are either stock chassis or fabricated chassis with either a Home Built Body or the more sleek Template Body style. This division is for the drivers who are looking for something a little faster to drive than what the Pure Stocks and / or Sport Stocks can offer. There may be other drivers with a Street Stock at a neighboring track who want to add those extra parts and pieces to bring it to the Big “O” and compete at higher speeds without having to build an entirely new car. These cars top out in the high 16 / low 17 second range around the 3/8s (0.375) mile high-banked paved oval with average speeds of over 90 mph.


Chet’s Auto Service/ Brown & Sons Auto Parts Pure Stocks:

If you’re looking for action, keep your eyes on this class as they will never fail to make any race night exciting. These cars are American Made, rear wheel drive cars with a stock frame and relatively stock suspension. These cars will almost always be trading paint with one another as three wide action is commonplace. Powered by a 350 or 400 cubic inch motor, you’ll see lots of horsepower on a smaller tire, creating one of the wildest features of the night. The Pure Stocks race around the 3/8s (0.375) mile high-banked paved oval in the low / mid 19 second range and can get up to 80 mph and more.


BigHause Sport Stocks: NOT SCHEDULED FOR 2014!

Owosso Speedway’s economy level division; this class is designed as a budget division where new drivers can enter into the world of short track racing without spending a fortune, as well as seasoned drivers who are serious about racing but work with a more limited budget. It’s the best division for learning the concepts of racing while preparing to move up to a rear wheel drive class. The Sport Stocks put on a great show at the Big “O” with constant three, four, and sometimes even five-wide racing! Most any 4 cylinder or 6 cylinder front wheel drive car can compete and run very competitively. No modifications can be made to the vehicles, except for those alterations involving the safety of the driver. You can build your own race ready Sport Stock for less than $2,000. The Sport Stocks race around the 3/8s (0.375) mile high-banked paved oval in the mid / high 19 second range and can reach speeds of almost 80 mph.

Midwest Racing Scene Powder Puffs:

Our Powder Puff Division is really starting to grow. In year’s past, many tracks had a Powder Puff race once or twice a year and some tracks had a weekly series where the gals were serious racers. The Powder Puff racing has scaled back across the country and yet more women are getting into racing and competing with the guys. In 2010 we started bringing the series back so that the gals could race with the gals. In 2013 we expect to have 12 – 14 competitors for the 8 nights of racing and quite possibly more! Our gals race a Pure Stock race car. These cars are rear wheel drive and are required to have street legal radial tires. We always schedule our Powder Puff races on the night that our Pure Stocks are racing because many of these women will be driving their husband’s cars! We always have Pure Stock drivers that would love to see a woman drive their car, so if you even think that you have a desire to race a car, please let us know and I’m quite sure that we can find you a seat! “Girls rule at Owosso Speedway!”

Main Event Series Super Late Models:

The premiere division at most short tracks for decades, the Outlaw Super Late Models are relegated to traveling to different tracks for special events. These outlaw bodied cars are built for speed and handling and you’ll find the best drivers traveling from all over the Midwest and even Canada piloting these racing machines. These cars will average close to 110 mph around the 3/8s (0.375) mile high banked paved oval with top speeds measured at over 130 mph in the middle of the straightaway. You can expect laps in the mid to upper 14 second bracket, while racing two and sometimes even three wide all night long! An average Outlaw Super Late Model will have upwards of $50,000 and more into a typical operation.
