[V8] Track F/R

[Tim Hollister]

the farther out you move the wheel away from the hub the more stress you apply to the hub and
suspension. it acts like a lever, the longer the handle the more force applied. I have personally
repaired quite a few cars who's owners put excessively offset wheels on and usually they burn up
wheel bearings quite rapidly, or in more extreame cases they snap off spindles. our cars are built
a little better but the loads are the same.
