I ordered these for my B7 A4 because both of my left shock absorbers had burned out. Installation was pretty easy, but I would definitely recommend someone with experience to help you. The included instructions weren't step by step so we DIYed it on the Audizine forum and it pretty much covered everything. Be sure to inspect the strut mounts and rear upper/lower shock mounts if removed. It would be a good idea to replace them when they wear out. The fronts are easy to adjust by hand, while the backs are a bit trickier and require patience. The chassis is a little tighter than the sports chassis, but still comfortable with a moderate depth. All in all, this is a great set of cheap coilovers!
