I ended up buying a control arm kit for s4, which is supposedly more resistand and heavy duty. The parts look really good, just like one of the above posters said, the finish is impeccable, hopefully the quality is the same. And I am getting this kit done as we speak for just 300 bucks. I had to negotiate with those mechanics, since they initially told me 550 for all work. 300 bucks sounds good to me though. I'll let you guys know how it feels to drive with brand new control arms and bushings.
