RFK Racing’s Drivers in Search of Playoff Breakthroughs in Iowa
Following Wallace’s success, attention turned to RFK Racing teammates Chris Buescher, Ryan Preece, and Brad Keselowski, all seeking their first wins this season to secure playoff berths. Positioned at varying points around the playoff cutline, each driver faces pressure to deliver a strong performance at Iowa. Their past success in the NASCAR Xfinity Series at this track adds to the anticipation, with Keselowski boasting three Xfinity wins here, including the inaugural 2009 race. Buescher’s 2015 Iowa victory and Preece’s milestone first Xfinity triumph in 2017 highlight their potential to alter the playoff picture once again.
Challenges Presented by Iowa Speedway’s Updated Surface
The 2024 repaving of Iowa Speedway’s lower lane corners introduced a major shift that has continued into the 2025 event, requiring drivers to adapt quickly to the increased grip and tighter racing lines. This resurfacing reduced the number of viable racing lines compared to previous years, emphasizing the importance of precision in negotiating the lower lanes. The altered track conditions have created a distinct challenge for NASCAR competitors, even those with extensive experience in other series at Iowa. Teams and drivers have leaned on last year’s insights to optimize setup and strategy, aiming to master this transformed racing environment as the regular season winds down.
“Before, the wide, sweeping corners of the 7/8-mile oval presented plenty of racing lines, and offered drivers the opportunity to choose where to place their cars in the turns. Now, the fresher asphalt offering more grip is at a premium, and getting your car into the lower lanes is crucial.” —Narrative from source
