Just over a week ago, NHRA rule changes went into effect regarding the Pro Modified class minimum weights. The ADRL then followed suit, though a few differences exist.

Under the new class weight guidelines, supercharged Pro Mod competitors can offload a little extra weight — in both NHRA and ADRL competition, the minimum weight has decreased by 50 pounds, bringing the new minimum to just 2600 pounds. The ADRL’s new Pro Mod weight changes don’t stop there. Nitrous-assisted ADRL Pro Mods will be required to put on a little weight–50 pounds, unlike their NHRA counterparts, who saw no change. ADRL teams running turbocharged cars will see no change–their weight requirement stands at 2650 pounds.

ADRL’s Pro Modified class has proven to be an extremely talented, world-class field, punctuating an already successful debut season. It begs the question–why start making changes in such a successful class? ADRL’s director of Technical Services Chris Bell says, “After a tremendous amount of work and thought, we feel this is the correct move to balance out the different power combinations in the Aeromotive Fuel Systems Pro Modified Class. Performance-wise, this will create even more balance in one of the ADRL’s standout classes.”

Bell went on to say that not only do the changes help racers, it allows them to put on a better show for race fans.

“We believe that these changes will give the fans even better racing in a class that has already featured some outstanding action in its first year in the ADRL. This has already turned into a great class, and with these adjustments, it will give fans even closer racing.”

Top Pro Modified drivers will face the change almost immediately, with the first event featuring the weight changes effective today as qualifying opens at Dragstock IX at zMAX Dragway in Charlotte, North Carolina. The NHRA Pro Modified adjustments will take effect at the next stop on the NHRA ProCare Rx trail at the Mac Tools U.S. Nationals in Indianapolis over Labor Day weekend.
