Kyle Larson was back in NASCAR's victory lane Sunday for the first time since he publicly used the n-word ... and Bubba Wallace was one of the 1st people to congratulate the guy.
Just 11 months after Larson infamously dropped the slur during a virtual race last April ... the 28-year-old smoked the field to win the Pennzoil 400 in Las Vegas.
And, not only was Bubba waiting for him on the winner's stage to give him a handshake and a hug ... the most famous Black driver in NASCAR also said he was "proud and happy" for Larson afterward.
