   wheels with a greater offset can induce bump steer

   Just wider wheels in general will cause bump steer as they are running over more of the road surface therefore finding more bumps. Also, when mine was lowered the bump steer was unbelievable but i don't even notice it now so must just automatically correct it without noticing. Annoying i know, but nothing to worry about.

   When you increase wheel width it is more likely that one part of the wheel will hit a bump when another part wont, creating bump steer. And lowering the car increases the KPI (or equilvilant in a Macpherson strut. This is the angle that creates torque steer. Same thing happens with bump steer
