Big congratulations to Casey Moore and the whole crew on bringing home the win this weekend in Lil Gangsters at Xtreme Raceway Park. The Boostline 408 did its job, but it takes a great driver, a great team, and a lot of hard work to park anything in the winner’s circle and they got it done! Thanks for trusting Boostline Performance to be part of it. It’s always rewarding to see our customers succeed, especially against such a tough field of competitors. Congratulations again to Casey and everyone involved in the program. We’re proud to be along for the ride.
