034Motorsport’s Density Line Adjustable Upper Control Arm Kit for B9 Audi A4/S4, A5/S5, and Allroad replaces the fixed factory front upper control arms to allow for precise, independent camber adjustments. Featuring CNC-machined billet aluminum construction, high-durometer rubber bushings, and genuine Aurora spherical rod ends, Density Line Adjustable Control Arms are limit unwanted deflection in the suspension, resulting in tighter handling and more precise steering response than even brand new factory control arms can offer.
