Ashu is stating that lowering/not lowering a car doesn't effect whether it will rub. It just affects the likelyhood of said rubbing occuring.
Aka if you lower your car and it rubs, it meant it was probably rubbing before you lowered it, you just didn't notice it cause it wasn't very frequent.
Usually when someone installs a combination tire/wheel which causes rubbing, they'll state it doesn't rub, cause when driving in a straight line, it doesn't.
Its when you take a turn hard (maximizing suspension travel), hit a pothole, speed bump, or bring along a full group of friends or fill the trunk...that the car lowers enough to increase the likelyhood that said condition will meet where the fender lip touches the wheel.
On the Mazda 6 there is a widespread confusion because of this fact, as there is a large # of people going around with combinations say they aren't rubbing, with an equal or greater # saying they do.
