Classes & Drivers

Written by SMS Admin.

Springport Motor Speedway features several different racing divisions and you'll have the opportunity to see multiple racing classes over the course of the 2015 racing season.  CLICK HERE to meet OUR DRIVERS.

Saturday Championship Classes: 
Springport Motor Speedway's Championship Classes are run regularily on our Saturday Event Schedule.  These classes will be tracked by Springport Motor Speedway with points and celebrated at the end of the season with a Banquet, complete with food, fun & trophies. While run regularily, they are not run every Saturday Night please visit the 2015 Schedule to confirm which classes are running on any particular date. 

Super Late Models: These are the baddest, fastest full fendered stock cars in the world.  These 700+ horsepower beasts feature the same Super Late Modelssmoke under the hood that you'd find in a NASCAR Cup level car.  Custom designed for the short track, these full tubular framed vehicles feature 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, fabricated with sheets of aluminum, shaped for speed and aero dynamics, & built engines. These cars will race around the 3/8s mile progressively banked paved oval an average of over 100mph. An average Super Late Model team will spend anywhere between $10-60,000 into their entire program.

Modifieds : Springport Motor Speedway is known as "Modified Country"; the #1 favorite destination for Modified Racers across 279535_10150306853987040_275251787039_9666132_7850697_oMichigan, Indiana and Ohio, when fans are looking for the best modified racing available, they come to the Port. These cars are almost completely Modified (Hence the name) with the one exception of a factory production front from a 1960 or newer American Made passenger car. These cars have a stock front sub frame with a tubular center and rear section of the frame. With their sleek outlaw open wheel body on them, they travel Springport Motor Speedway at just about the same speeds and times as Super Late Models, on the 3/8s mile progressively banked paved oval and average nearly 100mph. This division, first started in the state of Michigan in 1985 and has evolved into one of the most popular divisions in the country with their uniqueness in body style and open cock pit design and have always been one of the most exciting divisions to watch year in and year out.

Stock Cars (ABC) Stock Cars - ABC Street StocksThe ABC Stock Car Series is designed for many different variations of stock cars which are currently racing at most local short tracks in Michigan and surrounding states. The most common classes of cars are typically known as Sportsman, Street Stock, and Pure Stock. Other names for allowable classes to compete in this series might be Pro Stock, Super Stock, Factory Stock, Lead Sled, and Bomber. This series is designed for current up to date race cars as well as what many consider to be old and outdated race cars.

The basic ABC Stock Car is V8 powered and rear wheel drive. Teching in this series is very easy since all areas of enforcement are clearly visible. Teardowns are not needed in this series. In addition to the requirement of V8 and RWD, there are some ultimate limits to what is allowed. Those limits are covered in these rules.  Even though there is a very wide range of cars allowed in the ABC Series, the basic concept allows everyone to be competitive because of the feature race format. The generic ABC name is derived from the features that will be run, A-main, B-main, and C-main. With enough cars present, there can also be a D-main, and even an E-main or more. There will always be 12-24 cars in each feature, therefore, only a total of 36 cars are needed to run three feature events on any given night. Yet the format allows for an unlimited number of cars to race since additional features can be added.  The ABC concept allows everyone to be able to compete in a feature along with other drivers and cars of similar speed. There are no consi races or semi features. Everyone qualifies for a feature, the A-main, B-main, or C-main, depending on the qualifying times. (or D-main, E-main, etc)

The most important rule is this: Any car that is deemed too radical and too much outside of the rules of typical stock car classes that can be found competing at various other area tracks will not be allowed. With that said, the rules for this series are fairly open, but will be controlled by SMS officials if necessary. Interpretation of these rules is for the SMS officials and Final decision is in the hands of the Technical Director Dan Bailey.

ddSport Stocks : The Sport Stocks are an entry level class at Springport Motor Speedway with enough flexibility in the rules to allow racers to grow as their abilities as drivers and car builders increases.  RWD Four Cylinder Cars like Mustangs and Four Cylinder Trucks like Rangers and Rams race against FWD Four and Six Cylinder Cars like Dodge Neons, Chevy Cavaliers, Honda CRX or Dodge Intrepids.  The rules allow entry level racers to compete with a minimum degree of skill required to start, but allow the cars to become race machines. So whether you have a bone stock enduro machine or the baddest fastest mini-stock on the block, you'll find a home at Springport Motor Speedway.

Visiting Classes:
Sprinport Motor Speedway will play host to Several Invitational Type events Titled our Sunday All Star Series.  The focus of this competition is to invite the best of the best in Michigan, Ohio, and Indiana and host them in a competition to have them settle the score for who really is "IT".  Watch for more details as the schedule firms up. 

CRA Super Late Models
324914_10150271183538100_540543099_7680728_6614364_oComing to SMS on June 16th - with Special guest Kenny Schrader.  

The Champion Racing Association (CRA) is a racing sanctioning body that primarily oversees the scheduling, administering, and officiating of the CRA Super Series for Super Late Models.

The CRA Super Series is a touring series for Super Late Model stock cars mainly in the Midwest, but schedules special events anywhere in the eastern United States.

The CRA Super Series utilizes stock appearing cars, which resemble the Impala, Fusion, Camry and Charger we see on the street today. Underneath the stock appearing body though, is some of the most advanced stock car racing technology being used anywhere. The typical engines are 358 cubic inches and have a compression ratio of 9 to 1, and use aluminum heads. Atop the engine is a modified 390-cfm carburetor.  Competitors may also use a special Sealed Engine that is only available from two certified builders. The suspension and frames are designed specifically for racing and the safety requirements needed. The car rides on a mandated Hoosier Racing Tire which are mounted on 10-inch wide wheels. The top speed, depending on the track and gearing, could easily be 150 mph.  For more information, visit the website at
CRA All Stars

Coming to SMS July 1st.

The All Star Series use the same bodies that the supers do, but use a crate motor.



Dwarf cars are 5/8 scale replica models of vintage 1928-1948 American made automobiles.  They have full steel roll cages; sheet metal bodies, and powered by 4 cylinder motorcycle engines up to 1250cc.  They have full racing suspension and are capable of speeds over 100 mph (160 kmh) on the straight-aways.  With their size and quickness, they are perfectly suited to asphalt track oval racing.

Dwarf cars use motorcycle engines as power plants, bringing interest from outside the normal "auto" racing crowd.  Not just Fords and Chevy's fighting it out, but Suzuki, Kawasaki, Yamaha, and Honda as well.  The sound of 4 cylinders dwarf cars at 11,000 rpm has quite an appeal!  The weight to horsepower ratio is even greater than a full size late model stock car.

Dwarf cars are "real" race cars, not family go-karts.  With modern design suspension, Dwarf cars are achieving speeds similar to the fastest full size cars.

Dwarf cars are inexpensive to buy.  A brand new roller car, complete less engine, drive shaft, and headers is about $7000.00.   Most engines are supplied through the salvage pool and typically cost between $1,500 and $2,500.  Sometimes you can find a used dwarf car ready to race for under $3500.00.

Dwarf cars are economical to operate too.  The costs to race a competitive full size car range from $200 for a sportsman type late model to $1000 in a sprint car per race and that's if nothing gets torn up!  Dwarf cars, on the other hand, cost less than $25 per race, for fuel and an oil change.  The cost-per-racing lap is the lowest in motorsports today.




Legends car racing is a style of race car, designed primarily to promote exciting racing and to keep costs down. The bodyshells are 5/8-scale replicas of American automobiles from the 1930s and 1940s, powered by a Yamaha motorcycle engine. The sanctioning body for Legends car racing is called INEX.

Legends Cars are a "spec" series, meaning all cars are mechanically identical, with the exception of 3 styles of car (Standard coupe, 34 Coupe, and Sedan) available with 10 types of body styles. (New cars are currently offered with only 7 body styles, however many used cars exist with the "older" styles)
