33mm offset (on the SR5) or a 27mm offset (for the GT-S). The
previous Celica/Supra wheels came with an 8mm offset, which pushed
the wheel out and increased the scrub radius by almost an inch past
what Toyota intended. Ideally, having a zero scrub radius (i.e.
having the Dave, or wheel pivot, point at the same spot as the
center of the contact patch) is best, since the tire will steer
about the same point as where the kingpin axis intersects the
ground. More scrub radius means a larger torque moment, which
increases both resistance to steering inputs and the... //
