The Bilstein B12 (Pro-Kit) suspension kit for 2003 Audi A4 Cabriolet is a complete front-and-rear package pairing Bilstein B8 dampers with Eibach Pro-Kit springs to deliver a modest fixed-height drop and more controlled handling. Progressive springs yield precise response and enhanced driving dynamics. Each kit is tuned for the application to provide even lowering between 24–40mm and predictable on-road control.
