I have read conflicting ideas about angling the axles so the wheels ride away from the car body, some say this makes the car ride straighter and reduces wheel wobble and friction others say it greatly increases the friction against the axles head.
Please help I am very confused now, and my son's district race is this weekend. Thanks for any help.

It makes for a straight, fast, easy to align car especially with-out a test track.
Drill the body with a Pro Body Tool, straighten your axles with a Pro axle press and polish then. Mark the axle @ .350" from the head and put a dot at 12:00 on head with a sharpie. Instal the axle into the Pro Axle Press at the .350" mark with the dot on the head down and slightly bend the axle with a light hammer tap. I use a digital caliper to measure from the head of the axle to the work bench to verify my bend. On the rears .015" and .010" on the front. Install the rears with the dot up at 12:00 as well as the front (dominant wheel).
The car should roll forward and backwards with the wheels staying on the axle heads. If not. rotate slightly fore and aft untill both are perfect and do not migrate. Use slight rotation of the front axle to steer. There are several good table top formulas on here (someone chime in) but 1" drift towards the dominant front wheel over 6' test roll will get you going well.
The trade off is positive vs. axle head to hub face friction.
