America's Racing Masters
300 horsepower. Any manufacturer. Built in your garage.
A dirt oval class where driver skill wins, not the checkbook. Pump gas, modern engines, and a tube chassis anyone with a welder and a grinder can build.

Rules freeze a class in the decade they were written. Most of us remember when a 400 small block Chevy was everywhere. Now the aftermarket block costs a few thousand dollars and up. Old street car chassis are getting hard to find, expensive, and unsafe to build on.
America's Racing Masters follows what the manufacturers build today. That keeps parts cheap and plentiful, and keeps the manufacturers invested in short track racing. Not one component on these cars has a single supplier.
These rules come from more than three decades in short track racing as a driver, car owner, builder, crew chief, competition director, and fan. They are based on real enforcement, not theory.
Naturally aspirated all aluminum overhead cam V6, about 300 horsepower stock. Stock internals. Factory computer with factory rev limiter.
General Motors, Ford, Chrysler, Toyota, Honda, Hyundai and Kia, and Nissan. Every engine built by the millions.
87 to 93 octane unleaded pump gas. No ethanol blends. No exotic fuels.
Purpose built steel tube chassis. Front or rear engine. Front or rear wheel drive. Built in a home garage.
Steel components only. Steel shocks with no reservoirs or remote adjusters. Cast iron calipers, rotors, and drums.
15 inch steel wheels. Department of Transportation approved tires, 4 ply minimum. Tire and wheel must pass a 10 inch gauge.
Every car is checked and certified legal before it races. Tech uses electronic software, a whistler, a dial indicator, a spring tester, an endoscopic camera, and a portable chassis dynamometer. If tech cannot talk to your engine computer, you do not race.
Get caught cheating and you sit out a full calendar year. Do it again and you are done with this class for good. Gaming the rules drives cost up for everyone, and racers have carried this sport long enough.
This class is built to make racing pay the people putting on the show. Promoters get a full field of affordable cars and a format that fits a tight night. Manufacturers get their own engines racing on Saturday night. Every major manufacturer is invited.
The first car is being built now to prove the price point holds. Raw steel for the chassis was bought October 9, 2026, for about $700. Drawings and the full rules are at the bottom of this page.
Racer, builder, promoter, or fan. Leave your info and you will hear when the first car hits the track.
America's Racing Masters is an unspec spec class built around physics, accessibility, and driver skill, not spending. Money does not buy a meaningful advantage. Creativity, effort, and driving ability do. Anyone competent with a MIG welder and a grinder can build their own car. These rules will change as the auto industry changes, so the class keeps following what manufacturers actually build.
Design priorities: safety first, reasonable price, encourage innovation. Simulated lap times are in line with most existing street stock classes, sometimes faster.
The list is manufacturer based, not model specific, by design. It prevents scarcity and boutique loopholes, keeps cost low, and simplifies tech. Special trims rated above 311 horsepower from the factory are excluded. Penalties are set by the competition director and promoter.
Cost on October 9, 2026: about $700.
