The NMRA‘s new Street Outlaw class has been taking shape so far this season thanks to incredible performances from the likes of star racers Sean Ashe, John Urist, Jason Lee, and Phil Hines, among others. Since the Street Outlaw class is brand-new, the rulesmakers have been keeping a close eye on the performances of these racers in order to keep a tight racing field moving forward. Also, the Renegade class underwent a number of changes in the offseason designed to tighten up the class, and now that there are three races completed this season, the series is releasing a couple of rules adjustments designed to tighten things up in those top two classes. 

The Power Automedia titles have covered many NMRA races over the years and have always found them to be a great show – the performance racers in both series can achieve with the limited parts they are permitted to use is nothing short of amazing, and these changes should only serve to make the racing more exciting. Check out the NMRA’s class rules structures and purses here.
