I have the RMS strut rods in my car and have for a long time. They work well. I run the RMS upper arms, RMS strut rods, and poly bushing in the lower arms. With the suspension unloaded you can cycle it through its full travel by hand very easily. When I had poly bushings in the stock upper it was more difficult to move the upper arm by itself than it is to move the whole assembly with the RMS parts. The setup probably has 15000 miles on it now.
