I have had cars that only pull the left front wheel off and other cars that pull both, I could not tell the left front wheelies in the car. A friend told the car was doing that and then someone had it in a picture The other cars that pulled both wheels would hike the frontend up high enough and go forward and softly set the tires back on the ground enough to tell me that something unusual had occurred felt goog on the acceleration, no bad feelings on set down
