Q & A Question: What is the NVH of these upper control arms compared to stock?Answer: If installed with the supplied grease the NVH is minimal compared to stock while improving the overall handling of the car.Question: What makes these uppers better than factory? Answer: The factory control arms are stamped steel and flex quite easily. They also come with a large rubber bushing and contributes to a very spongy feeling from the rear suspension. Over time the bushings will crack and fail due to all the flexing. The tubular design of the UPR arms eliminates the flex in the control arm and the urethane bushings with larger pin eliminates that spongy feeling.
