The two 2013 SRT Viper GTS-Rs are undergoing last-minute tuneups after successfully completing warm-ups this morning prior to the American Le Mans Series (ALMS) race this afternoon at Mid-Ohio Sports Car Course.

There was some concern yesterday when the No. 91 car blew an engine and had to cut short its qualifying run. But team mechanics worked the problem and those in the know say the car is good to go.

"We're still making some changes on the suspension side," says Gary Johnson, Road Racing Manager, SRT Motorsports. "We're limited on the powertrain side, but overall things are going well."



Because of having to drop out of yesterday's qualifying heat, Dominik Farnbacher and Kuno Wittmer, drivers of the 91 car, will be starting today's race in the 12th -- and last -- position. Marc Goossen and Tommy Kendall, piloting the No. 93 Viper GTS-R, will be starting 10th.

The race is a timed event and runs two hours and 45 minutes.

Coverage begins at 2 p.m.(EDT) on ABC.
