While I think the rear upper links are a good mod, the rear guide rods are the better individual mod. However, if you can afford to do both then it is easier to do both at the same time. I did the rear guide rods several months ago and they made a noticable difference in the way the rear of the car felt. I decided to go ahead and add the upper links at the same time as the sub frame bushings in order to finish off the M3 suspension mods in the rear of the car. I had previously completed the front M3 suspension mods.
