Installation complete. The thrust arms didn't make it yet- they are still working on the prototype. There is no additional road noise from the control arms. I'll probably have to wait to get the car on the track to actually notice any difference. I sent my arms to them to have the bushings pressed in. The 2 bushings and installation cost $200. I keep you posted after I log some more miles-
