I need to replacing the front control arms (upper and lower) which have worn on my S4. My Audi mechanic keeps telling me to find an aftermarket kit, bring it In and they will put it on for me. Problem is, every time I ask them to recommend a kit, they don't have recommendation. And anything I recommend, they say it isn't a good kit. Anyone have a kit they would recommend? Meyle, Blauparts, ECS?
