Cam Waters has exploded at Tickford Racing teammate Chaz Mostert after an early clash at the Bathurst 1000 that has put his Falcon in the garage.
Waters, who qualified sixth fastest for Sunday's endurance classic, handed over the reins to co-driver David Russell after 20 laps.
By lap 21, his car had limped back to the garage and possibly retired from the race by Mostert's move.
The young gun was given plenty of room by Russell at Forrest's Elbow, only for the 36-year-old to close the door and make contact with his teammate, spinning into the fence.
