Well, on all of my cars. I dropped them no more than 1.5 inches and I just got a wheel alignment and everything was fine. Especially when I had my 97 Mazda. I dropped 1.5 all around and forgot to get an alignment. 6 months later The inner tires were so bad that the steel was showing (Negative Camber) Although the rear was perfectly fine. I got a 4 wheel alignemnt and since then everything was fine.
