Prof. Prudence Goyette I 25 May 2025

Is the thrill of dirt track racing calling your name? The IMCA (International Motor Contest Association) racing scene is a hotbed of action, offering a diverse range of classes and fierce competition. From modifieds to stock cars, hobby stocks, and everything in between, there's a place for every driver and every budget.

Navigating the world of IMCA racing can seem daunting at first, with a plethora of options for cars, parts, and setups. But fear not, this guide is here to help you understand the landscape and find the perfect racing machine to conquer the dirt oval. Whether you're a seasoned veteran looking to upgrade or a newcomer eager to jump into the fray, understanding the nuances of IMCA classifications and the available inventory is crucial for success.

The IMCA racing community thrives on a vibrant marketplace, with cars and parts constantly changing hands. Veteran racers often upgrade their equipment, leading to a healthy supply of used cars available for purchase. A savvy buyer can find incredible deals on race-ready machines, sometimes needing only minor adjustments to suit their driving style. For example, a 2018 Taylor IMCA modified, a complete roller minus engine, transmission, seat, and lead, might be the perfect starting point for someone looking to break into the modified class.

From old-school Camaro street stocks to purpose-built IMCA modifieds, the options are diverse and exciting. Consider a race-ready 1969 Camaro with a 4-bolt main 350 engine a true classic with proven performance. Or perhaps a 2022 Vanderbuilt IMCA modified with 70 nights on it, ready to hit the track immediately. The white 2019 Vanderbuilt with 125 nights represents a different price point and potentially a different level of wear and tear, providing choices for racers with varying budgets.

Building a competitive IMCA car often involves piecing together the best components from various manufacturers. AFCO shocks, Wehrs suspension cages and climber j-bar mounts, Winters quick-change rear ends, and Wehrs brake floaters are just a few examples of the high-quality parts that racers seek out. Even seemingly small details, like a new Optima battery, an AFCO 24 radiator, an MSD box, and a Sweet steering shaft, can contribute to a winning combination.

The choice between buying a complete car or building one from scratch is a personal one. For those with the skills and time, building a car can be a rewarding experience. Starting with a chassis kit, such as a 2025 Terminator hobby stock chassis or a 2025 stock car chassis kit with a powder-coated frame, bumpers, and body mounts, allows for customization from the ground up. Adding a fuel cell, Tilton pedals, gauges, a rear end, IMCA wheels with American Racer tires, a window net, and a quick-release steering wheel completes the transformation.

For those seeking a quicker route to the track, numerous complete cars are available for sale. A 2013 Wayne Larson Racing Specialties stock car with few nights on it offers a compelling blend of performance and value. The addition of an 80s Olds Cutlass body adds a unique touch. Similarly, a 19 Lethal Chassis IMCA dirt modified, equipped with a 604 crate alky carb, a quick-change rear end, and Penske shocks, represents a serious contender in the modified class. A used engine with only 15 nights on it from Arneson's adds further value.

The IMCA marketplace extends beyond complete cars, encompassing a vast inventory of parts. From dash aluminum kits used on IMCA, USRA, or Wissota stock cars to specific engine builds for IMCA or NASCAR series, the options are plentiful. Builders like Jet Racing Inc., home of multiple IMCA national champions, offer expertise in crafting winning machines. Their reputation for building top-tier IMCA modifieds, coupled with their knowledge of technology and racing, makes them a valuable resource for racers of all levels.

Whether you're buying, selling, or trading, the IMCA racing community is a dynamic and engaging environment. Online forums and classifieds, such as RacingJunk, are excellent resources for connecting buyers and sellers. Remember to check the rules and regulations for your specific class and series, and don't hesitate to ask questions and seek advice from experienced racers. With the right preparation and the right car, you can experience the thrill of victory on the dirt oval.
