Bumblebee's racing-sponsors deco is full of easter eggs!
84, obviously
Omega Supreme
S.T.A.R.S.
Pre history Autobots (

Possibly a Minicon symbol?
Beast Machines Dinobots!!!
Sumdac
Preschool Go-Bots
And possibly more on the other side?
Sideswipe has the TransTech Autobot symbol too, and it seems to say "Lithonian Drivetrain" as well as something else I can't make out.
That's just too cool.
