So I have my car set up with 2.5 deg cant on back axles and 1.5 deg cant on the front dominate wheel. If I understand correctly you want your front axle bent down causing the wheel to migrate to the car body. This is to minimize the contact area the wheel has with the center rail. I get that. My question is how do you align the car on your board with the wheel rubbing on the car body? Won't the car body contacting the hub possibly change the toe of the wheel? Won't the wheel position on the axle head be different on the track when the wheel gets pushed out to the axle head? How do I know I'm getting the correct allignment on the track?

Hard to do to best performance without a track.
wheel will naturally rub the body during tuning in a pos camber situation without the rail to keep it out. we do a 18" hi free roll on the track and tune for max roll out to get base line. but since we have a track we can finish tune for time. every car a little different.

When I tune for rail riding my dominant front wheel with positive cant migrates into the car on the tuning board. I usually set up about 6 to 9 inches drift over 6 feet. This can differ considerably depending on the car. On my track at the starting gate I push the wheel into the rail and make sure the car body is against the wheel inner hub. The car stays this way all the way down the track - wheel in against the rail and against the car body. When notching the front of the car for rail riding I make sure that when the wheel is against the rail and the car body is against the wheel hub that the center line of the car is on the center line of the rail. Hope this helps!
