Proud member here of NMMRA - the New Mexico Motor Racing Assn., a steel block, non-wing sprint group for over 50 years. We run a mix of everything between 305 and 406, with a set of rules that distinctly favors the low-budget beginning racer. With our typically dry-slick tracks here in NM, the extra weight and HP of the 406 is not necessarily an advantage. We invert the top 16 for the "A" main and arrange heat races by point average, giving more drivers a chance at getting a checkered flag. If interested, check out our website at www.nmmra.com
