what is the scrub line :confused:
From the PA code:
A scrub line is an imaginary surface created if lines were drawn from bottom of wheel rim on one side to bottom of tire on other side. When lines are drawn from both sides an “X” under the vehicle suspension is created. No suspension or chassis component shall be below top portion of this imaginary “X”.

It's required so that if one tire goes flat, no part of the suspension or frame hits the ground.
