I was considering lowering the car, but I drive on many uneven PA roads and driveways, so it's probably best for me to stay at the stock height. I've been catching something on the bottom even with only 2 of my god-children (6 & 4) in the back seat, so it's not an overload situation. I catch mostly when starting up an incline. I've been driving over the same spot for 10+ years, and my Passat is the only car I've owned that catches there. Today I was looking at the car and realized that there's a noticeable difference in the height from front to back. Is it normal for the back end to sit noticeably lower than the front?
