Who knows - many possibilities.
Maybe he knew - or "they" believed he knew - something (about: NASCAR, another racer/racing team/vehicle, some company, some person, etc.) "they" didn't want to risk being disclosed(?) Or maybe his death was a warning/message to other(s) to comply/shut up/not whistleblow(?) Or maybe it was one of the ~3/10 that are genuine accidents.
I like the idea of NASCAR being a corrupt sport that sucked a lot of money from the fans. Once the money began to drop I bet some of the good honest drivers began to speak out about the corruption in the sport and the DS didn't like that thus maybe they sent a message to Biffle to keep his mouth shut.
