Starting in 2012, Jimmy Mars Racing branched out and started to build MB Customs Modifieds! Designed by Jimmy Mars, Chris Mars, and A.J. Diemel, the new MB Customs Modified has taken the country by storm and has won numerous WISSOTA, USMTS, IMCA, and UMP feature events. Whether it's been Jimmy Mars winning the 'Legendary 100' at Cedar Lake (WI) Speedway and the 'Punky Manor Challenge of Champions' at Red Cedar (WI) Speedway or Rodney Sanders amassing thirty-five (35) feature victories in 2014 on his way to a USMTS Championship or Jason Krohn racking up multiple USMTS triumphs, drivers piloting MB Customs machines are definitely turning heads at racetracks across the country!

New WISSOTA, USMTS, IMCA, and UMP Open Wheel Modifieds are now available through Jimmy Mars Racing. Call Jimmy Mars at 715.235.4950 for more information and pricing!!!
