Had an alignment done (twice actually) and the car handles and tracks perfectly straight - the toes, cambers and thrust angles are all in the green. However, the steering wheel is about 2 degrees left hand down even after the garage set it all up a second time. Is there a way of adjusting the angle of the steering wheel without touching anything else? I've had the steering wheel off (OMP wheel) and tried to rotate it a spline but then of course it's just as bad in the other direction Thanks folks.
