The 38-year-old led a 1-2 finish for Subaru Motorsports USA in the Super Cars final, with teammate Travis Pastrana the runner-up.

"It means a lot to me," Speed said of the victory, his first since fracturing a vertebrae in a crash in 2019. "Coming back from a broken back is no easy task mentally [and] physically, and to come to a track like this that has got so many jumps, so many places where I have to trust that the car is going to make it, and really fight fears... every time I look at a jump I still think a little bit about breaking my back.

"I'm really proud of the progress I'm making."

Including bonuses, Speed earned 53 points for his victory. That puts him at 87 points on the Super Car standings, good for a tie with Red Bull Hansen's Timmy Hansen atop the leaderboard. Hansen finished in fourth behind younger brother Kevin on Sunday.

The series next heads to Arizona for a weekend of action at Wild Horse Pass Motorsports Park near Pheonix in November.
