I installed my HMS strut brace on Saturday. After driving the car for a few days I have noticed a difference in from end stability and a seat of the pants difference in handling all to the better. Now I need to work on the rear end problem the bouncing back and forth on certain types of bumps, at times drives my crazy. Does BMW have a fix for this situation? Someone suggested on this board KONI Sport adjustable shocks. I might go that route if I can find them at a reasonable price.
