I'm having a little problem understanding this problem, correct me if i'm wrong, but if the car hooks good and goes straight on the launch, why would you care if the left front tire is carried a little higher and long if the car is performing consistently. My car has always pulled the left front tire higher than the right side (4 link setup). We scaled it a couple yrs ago and did all the correct adjustments, the car runs straight as a bullit but still lifts the left front tire about 4" while the right is barely touching the track. It used to do 4 ft wheelies before scaling the car.
