SUMMARY
Using the current NMCA rules as a model, the previous sections were written by a six-racer committee whose members have extensive experience in Nostalgia Super Stock racing, including the national event series of the NMCA and Goodguys Associations, the regional event series of the Chrysler Classic events and also regional clubs and associations such as Nostalgia Super Stocks Inc. and the Texas Outsiders.
In addition, these rules and procedures reflect almost 20 years of both development and tradition in NSS racing. The committee is confident these guidelines will be able to competently administer NSS racing both now and into the future.
The committee includes Mark Artis of the Texas Outsiders, Doug Duell of the Dave Duell Classic, John Grinwald of Nostalgia Super Stocks Inc., Clay Kossuth of the Texas Outsiders, Jim Netherland of the NMCA series and Bob Wilkiewicz of Nostalgia Super Stocks Inc.
