I have intrax springs which are as low or lower than canuck springs, plus a kit and I rarely rub or scrape. You do have to change the way you drive over bumps or through dips. Like in off-roading, you should approach it one wheel at a time, not straight on. A lowered Alero is still fairly tall compared to some production cars like the the 370z. You should also learn how to drive in reverse really good because sometimes you will just find that back alley or driveway with a crazy angle
