Former Verizon IndyCar Series champion Tony Stewart said he would endorse another attempt at "the double" from Stewart-Haas Racing driver Kurt Busch, who ran both the Indy 500 and the NASCAR race in Charlotte on the same day this year.

"I'm 100 percent supportive if he wants to do that again," Stewart said.

"I thought for somebody that had not been in an IndyCar to go over there, and as tough as the IndyCar Series is right now, to have a performance like that was unbelievable. He did a phenomenal job."

Rahal talks wedding plans

Verizon IndyCar Series driver Graham Rahal was one of several guests who appeared at the IndyCar display at the Performance Racing Industry trade show at the Indiana Convention Center.

He was asked about his recent engagement to NHRA star Courtney Force and joked he'll have no role in the planning.

"(Future father-in-law John Force) said he's buy me a Lamborghini if we didn't have a wedding, and then he said he'd give us a certain amount of money if we held it in his backyard to make it less expensive," Rahal said. "That's not going to happen."

CFH team cuts deal with Indiana

Indiana Secretary of Commerce Victor Smith joined CSH Racing co-owners Sarah Fisher and Ed Carpenter in announcing a partnership in which the state will be an associate sponsor on CFH Racing cars for the Angie's List Grand Prix of Indianapolis, the Indianapolis 500 and the 2015 Verizon IndyCar Series season-concluding GoPro Grand Prix of Sonoma.

"Indiana is recognized as the motorsports capital of the world and we're building a reputation we like to say as 'a state that works,'" Smith said during the brief ceremony at the Performance Racing Industry trade show at the Indiana Convention Center. "This Hoosier team has delivered on the racetrack and it mirrors our state's success in building an economy and business environment that is attracting billions of dollars in investment."

Motorsports in Indiana is a multimillion dollar industry that employees thousands of individuals. IUPUI, a university in downtown Indianapolis, has the only motorsports engineering undergrad and graduate programs in the nation, and the Dallara IndyCar Factory next door to the CFH Racing facility supports multiple motorsports platforms.

"Sarah and I have built our lives here, built our businesses here and to partner with the state - the state that works - and show people that it is a great place to grow your business or start your business is our mission," Carpenter said. "It is a natural partnership."

The team operates out of a modern shop on Main Street in Speedway, Ind., near the Indianapolis Motor Speedway.

Carpenter competes in oval races (he won at Texas Motor Speedway in June and earned the Verizon P1 Award for the Indianapolis 500 for the second consecutive year in May) as the lone owner/driver in the series. Fisher, who started Sarah Fisher Racing in 2008, retired from Indy car competition in 2010. At 19 years old, she is the youngest female to compete in the Indy 500.

"Personally, the State of Indiana helped me back in 2008 when I had a sponsor that failed to pay, and one by one Hoosiers came together and had a viral campaign that raised almost $75,000," Fisher said. "It was such an impact on me to have this kind of community support so representing the state means so much to me."

Josef Newgarden enters his fourth season as the team's other full-season driver. The 2015 season kicks off in Brasilia, Brazil, on March 8.
