TOPEKA, Kan. (October 12, 2013) – The Sports Car Club of America Board of Directors approved recommendations from the Club Racing Board (CRB) on Saturday that impact both the Formula 500 and GT-Lite classes.

Beginning in 2014, specified water-cooled, four cylinder, four-cycle motorcycle engines up to 600cc will be permitted in the Formula 500 class. The General Competition Rulebook (GCR) will outline a set of rules to control the power level of four cycle engines to yield approximately the same on track performance of the current two strokes engines.

“The CRB has recommended, and the Board agrees, that there is potential to grow the Formula 500 class with these changes,” Lisa Noble, SCCA Chairman of the Board, said. “It’s very important to us that this not become an open class for 600cc engines, but that the new motors be introduced in a way that gives both the four-cycle and the two-cycle engines a chance to be competitive. Only engines as permitted by the spec line in the GCR will be allowed in the class.”

The Board of Directors also approved a proposal by the CRB to make GT-Lite a Regional-only class beginning in 2015.

Of note, this resolution is different than a previous proposal that would fold the existing cars into other classes. Individual existing cars may be classified on a case by case basis. This change is a direct result of input from competitors at the 2013 SCCA National Championship Runoffs.

Should 2014 reflect the resurgence of credible competition in GT-Lite at U.S. Majors Tour events, the CRB may request that the movement of the class to Regional status be held back.

Further details on the spec lines for Formula 500 will be available in the November Fastrack® News, available on October 20.
