I know this is a little off topic but in 2003 myself and my driving partner John Dearing took our
STOCK 2002 Viper GTS to the OTC (Open Track Challenge) 7 tracks in 7 days and we ran in the "Touring" class which meant street tires with a treadwear rating 160 or higher (no cheater Cups). We came in 2nd in 2002 to no other then Paul Mumford in his "beast" 2001 ACR. This year PMUM moved to the Unlimited Class in his Comp Coupe (which he won) Our new competition was a Mosler 900 coming in at like 2,000 lbs
To make our long story shortat the end of 6 days were were tied with the Mosler at 3 track wins each but alas our 3,400 lbs. stock GTS couldn't keep up on the last short, tight Derek Daly track and we came in 2nd again
All in all I think we made a pretty remarkable showing against and on paper superior Mosler MT900 in our stock Viper.
