Mars Race Cars, now a well-known source for dirt Late Model, Modified and Midwest Modified/B Modified chassis, had humble beginnings - born out of a shop on the family farm in Elk Mound, Wisconsin. For the Mars brothers - National Dirt Late Model Hall-of-Fame Jimmy Mars and his accomplished crew chief brother Chris Mars - they made do with what they had available to them and built their own Street Stock, starting their racing careers in 1985. With on-track success, competitors began asking for help and guidance from the brothers and from there, the racing program morphed to include chassis building for other high profile dirt racecar brand-names over the next 20 years. Eventually, the Mars brothers continued their ingenuity with their house brand, MB Customs.

Since the MB Customs brand began in 2008, the brand quickly became a leader in the industry - first on the dirt Late Model circuit, and then later in 2012 with the start of their now highly decorated dirt Modified chassis line. In 2015, the development of a Midwest Modified/B Modified occurred, and drivers have had a high level of success in that class throughout the nation as well. In total, MB Customs race cars have been driven to more than 2,450 wins in the Late Models, 2,970 wins in the Modifieds, and more than 770 wins in the Midwest Mod/B Mod ranks as of the conclusion of the 2024 season.

As the business has expanded from a one-car team to a successful Late Model and Modified chassis-building business in 40 years, Jimmy says one of the best parts is meeting new clients throughout the country and helping them run well.

"We've picked up wins in every sanctioning body, at every level of dirt Late Model and Modified racing, throughout the nation," Jimmy furthers. "An extensive amount of work has gone into ensuring our brand is successful and that drivers are supported at every step along the way. You let us know what your intentions are for your race schedule, and we'll be here to ensure your car is not only built to the correct specifications, but is also the best of the best, wherever you race."

When you decide to purchase an MB chassis for your race program, you quickly realize that Jimmy, Chris and AJ Diemel have ensured their 100-plus combined years of racing experience are carried throughout the process of production and afterward. This is complemented by additional staff who have all had long-term involvement in motorsports.

>> A Valuable Investment For Your Program
MB Customs chassis are quality pieces at market level for cost, and the racer behind the wheel is making a solid investment in their race program for the price.

"With increases in material costs and with operational costs on the rise, our prices have remained within what the market bears among other chassis manufacturers," explains Chris. "We need to keep the lights on, so to speak, but we also acknowledge a chassis builder plays an important role in the health of racing. We want to be fair in everything we do, because it only benefits us to ensure racing is healthy and its longevity is not in jeopardy."

When you purchase a new or used race car from Mars Race Cars, you leave with a car that is right where it needs to be to be in contention for a win when it's unloaded. Drivers start from the get-go with a well-rounded program, and the chance that frustration drives them out of racing after a few years is lessened.

"We pay great attention to every detail of every race car that leaves this shop," adds Diemel. "Even if you're buying a used car from us, it's been gone through thoroughly and leaves here in top-notch racing condition. That's the least we can do for our customers who have entrusted us with the major component of their racing programs."

"We've been on the other side as a customer," furthers Jimmy, "and we understand as competitors ourselves what people expect out of the partnership between a client and the chassis builder. We've tried to improve that relationship and take great pride in being available to provide timely responses to any questions a client may have, whether it's during the build process or throughout his or her season."
