Fast & Furious: Spy Racers Rise of SH1FT3R

Extremely simple in the spy racer mode pick one character like Tony Toretto win a championship/tournament with them then in your second championship/tournament pick another character like Layla, Echo or Cisco and when you win the second championship the achievement will unlock.

If you haven't gotten this like me after playing through the campaign pick the last championship (chasing shadows) as it's the shortest
