NASCAR star Ross Chastain says he's honored that his iconic wall-riding stunt is now banned in the rule book ... telling TMZ Sports, "I'm proud that I'll be the first and last guy to successfully do it.
Remember, the 30-year-old Trackhouse Racing driver went viral for his video game-inspired move at Martinsville Speedway last year ... when he shot from 10th place to 5th on the final lap to secure his spot in the Championship 4 by hitting the wall to reach insane speed to cross the finish line
While the move was considered legal at the time, NASCAR recently emphasized its rules to make sure the stunt isn't replicated in the future.
