Despite a long-term injury that prevented him from competing in the Bahrain Rotax Finals, Walker made a remarkable comeback to podium in the senior category.

To enhance his skills, Walker partnered with Indy 500 winner Buddy Rice and Brent Brush from Megapixel Management.

Throughout the season, Walker secured podiums at Road America and Indianapolis Motor Speedway, working closely with Buddy Rice and receiving support from Megapixel Management.

He was also approached by Samantha Tan Racing to drive their BMW GT3 car at the Indy 8 Hour in the SRO series in October of that year.

At the Rolex 24 Hour, Walker and his team led the race and maintained a top-three position for most of the event before debris issues put them out of contention for a win.

Walker secured a P2 overall finish in race 2 of the Super Trofeo series at Laguna Seca, marking a strong start to his 2024 season.
