My 2007 R56 S has just over 155,000 miles on it and the stock struts have been completely toasted for a while. These coilovers were a massive improvement, and ended up lowering the car a full inch with no scrubbing anywhere and no issues over speedbumps etc, currently have about 500 miles on them. ONE WARNING: The dampening adjuster knob extenders included for the rears work well but you will need to drill through the inside of the strut housing and they will come out directly next to the rear seat pivots in the cubby covered by the wall trim. Not a necessary install if you plan to not adjust them often though. Beautiful product and very happy with the results!
