DALLAS, Texas – TKS Motorsports and Austin McCarl have mutually decided to part ways, bringing an end to their three-year run together.

In three years together, TKS Motorsports and McCarl earned four victories and the 410 sprint car track championship at Iowa’s Knoxville Raceway in 2018.

This season ended with the team sitting third in points at Knoxville after racking up five top-five finishes and 10 top-10 finishes.

“We struggled to get into a good routine this season, largely due to the large number of rainouts early in the season,” said car owner Troy Renfro. “It was an okay year, but Austin and I decided it was time to go our separate ways. Tammy and I think the world of Austin and will do whatever we can to help him going forward.”

“It was great racing for Troy and Tammy and working with the crew,” said McCarl. “Winning a championship was a huge accomplishment and I’m thankful I had the chance to win it with this team.”
