Hello,
The rear springs in the 330xi are broken (apparently a common issue). In looking around I found that aftermarket springs all lower the ride height of the car, but are significantly cheaper than OEM. I don't have any strong desire to drop the car but if it saves me a few bucks I am fine with it. The question is that I have also read that lowering the awd model causes wear on some of the driveline components - that I would be willing to pay OEM to avoid. Does anybody here know if there are real downsides to putting the most moderate of aftermarket springs on an awd (eibach prokit)? The web says a drop of about 1" but I'm not sure if that is from the non-awd height or the xi, which rides higher.
