I have noticeable play in all my front upper control arms. I was looking at the 034 Motorsports kit ($375) or ($600), the ECS kit ($530), and the Purems kit ($590). Each control arm is approximately $120 each and I need four. I have an early build 2000 S4 with the aluminum uprights. So, it would be the most economical if I buy the whole kit compared to four. Can I use the $375 034 Motorsports kit and not use the lower control arms because I have the aluminum uprights?
