Dan Bilzerian is new face of NASCAR ... well, at least for one race ... 'cause the billionaire playboy's grill will be on the front hood of a car competing in Saturday's Sprint Cup Race ... TMZ Sports has learned.
So, how the hell did he make that happen? Dan's a huge poker player --and he recently beat the snot out of BK Racing owner Ron Devine.
But instead of forcing Ron to pay up in cash, Dan wanted to go all Ricky Bobby ... so he made a deal to get his mug plastered on one of Ron's NASCAR whips, which will be competing at Richmond International Speedway.
The final product is hilarious ... with Dan's giant bearded face right on the front of Matt DiBenedetto's #83 car. He also added a sticker of Dan's pet goat Zeus to the rear for good measure.
