XR Events, promoters of the XR Super Series, Pennsboro Speedway, and a number of growing regional events have launched the ONUM Dirt Modifieds, set to complement a number of XR Super Series events in 2024 and feature in what will be the highest paying Dirt Modified event of all time. The Big Deal at Mississippi Thunder Speedway in Fountain City, WI, is scheduled for May 30 to June 1, with a $100,001-to-WIN top prize, $2,500 to start, and over $300,000+ in total purse money.

ONUM stands for One Nation Under Modifieds and will utilize a multi-sanction rules package where bragging rights will be contested on the track, debated on social media, and celebrated in victory lane.

“It all goes back to the original Sunshine State Modified upset at East Bay Raceway Park in 2016,” stated XR Events CEO Barry Braun. “When an Iowa 604 Crate Modified shocked the field and won the world was turned upside down. It was a moment everyone still talks about and we hope to see duplicated. We want to combine the best Dirt Modified racers at mega events and put on more epic moments the fans will never forget.”

ONUM rules will allow for multiple sanctions to run together all year. Event rules may be adjusted to allow for the best possible competition at each track and will be posted well in advance on the ONUM website.

The ONUM Dirt Modifieds will support the XR Super Series Late Models at Ultimate Motorsports Park in Elkin, NC, on February 23-24, Volunteer Speedway on April 5-6, the Kokomo All Star Race in Kokomo, IN on July 12-13, the Yankee Dirt Classic from 300 Raceway August 30-31, and a season ending headline event from the Dirt Track at Las Vegas Motor Speedway, the Duel in the Desert on November 7-9.

Event purses and information will be posted within the next month on the ONUM website.
