Years ago I bought the turn in concepts bushing set. The rear 2002 wrx links I had were bent, but they were both bent the same amount so I installed the bushings thinking it was okay. When I couldn't align the car my friend pointed out the lateral links shouldn't be bent, and one was slightly more bent then the other. I did try to drive the 818, made it maybe half a mile down the road at low speed before turning around. End up buying swaged tubes and rod ends.
Turn in concepts wants 175 for the set, I'll take 75 shipped. You will need to press out the bushings.
