Extension for using Toyo RA-1 for spec tire classes
April 1, 2009 7:06 AM —
The National Auto Sport Association (NASA) announced today that rules in all spec tire classes will be changed effective immediately to allow the use of the both the Toyo R888 or the Toyo Proxes RA-1 until the end of the 2009 season. This change is being made in partnership with Toyo to better allow racers to use up remaining RA-1's they had on hand and ease the transition to the new R888 without racers having to replace tires before the end of their useful life. Rule updates will be completed shortly and posted to the main www.nasaproracing.com site.
