The ST Adjustable Lowering Springs for Audi A4 (B9) Sedan 2WD convert stock suspension into an adjustable height system without replacing shocks, working with both standard and electronically adaptive dampers. Built from chrome-silicon steel and tuned to application-specific spring rates, these springs lower the vehicle while aiming to improve steering response, stability and overall driving dynamics.
