Best of both worlds collide at USMTS vs UMP Spring Challenge

WEST BURLINGTON, Iowa (March 16)—Competitors from the two most powerful empires in the dirt modified universe will come together Friday and Saturday, April 2-3, to battle each other at the 34 Raceway in West Burlington, Iowa, in the inaugural USMTS vs UMP Spring Challenge powered by MSD.

While warriors from each faction have raced against each other many times in the past, this will be the first time that racers are permitted to use their regular organization's rules package. Drivers can follow the USMTS or UMP rulebook but no mixing of the two will be allowed. UMP racers must utilize the hard 60 tire on the right rear.

With one event in the books for the 23rd season of USMTS competition, this will be the first visit by the series to the 34 Raceway. Friday's main event will pay $5,000 to win and $500 to start, Saturday's finale has a $10,000 top prize up for grabs with a minimum $700 to start the feature race.

“We have had several races over the years in Illinois, Missouri and other regions featuring a cross-section of racers, but this will be the first time that each sanction can run their own rules package,” said USMTS President Todd Staley. “We’re hopeful for a great turnout of teams from both sides of the fence.”

Also running will be a trio of support classes both nights. Each class will allow weekly track or USRA rules. Sports/B-Mods can run their rules package with tires and everything. Stock Cars will be allowed to run the USRA carburetor rules if they would like to give the 4-barrel a try. Also running will be four-cylinder Tuners/Sport Compacts.

Stock Cars and Sports/B-Mods race for $500 to win both nights while Tuners/Sport Compacts battle for $200 to win. There is no entry fee in any support class and no licenses are required.

On Friday, the pits will open at 3 p.m., grandstands open at 5 and qualifying gets underway at 7 p.m. On Saturday, all times are one hour earlier with pits opening at 2, grandstands at 4 and racing action at 6.
