I bought my self a set recently, waiting til the end of the month to install them but people have installed these on their e46's and had no problems. Some complain about bounce and slight noises but those comments should be disregarded because they all improperly installed the coils or didn't replace strut and shock mounts when they installed the coils. And from what I see, these are pretty quality coils for the price, if you're looking for something just for daily driving, and just lowering your ride height to eliminate ugly wheel gap, then these are perfect for you. Hope this helps.
