hunter 408 Report post Posted December 30, 2013 hi guys, as some of you would have seen in the showroom, i recently updated my suspension to H&R sports springs with Koni yellow shocks. the setup is great rides nice handles bumps well, except when going in driveways as of last week. the high side (the side to make contact with the curb last), pops when it makes contact with the driveway curb. when the springs were installed, rubber sleeves were used over the coils to prevent noise from the progressive coils touching as some rubbing was felt on test drive. This was recommended by Keith at Stocks and my local BMW shop did the install so feel confident in this solution, is it possible the sleeves could have moved? has anyone experienced this type of thing before, and could it be anything other than noisy springs? I had the shop check all the end links, sway bars and associated bushings when installing to make sure they were all ok. Thanks in advance Quote Share this post Link to post Share on other sites
