Audi A6 C4 4A Bilstein B12 Pro Kit Coilovers - Stage 2 Fast Road & Track Day

The Bilstein B12 Pro Kit for the Audi A6 C4 (4A chassis) is a proper stage 2 suspension upgrade - monotube dampers, progressive springs, and precise valving tuned for fast road use and occasional track days. Not a show car pose, not a daily-driver compromise.

• Uses Bilstein’s B14 monotube dampers with adjustable rebound and matched progressive springs (not linear)
• Lowers up to 45 mm front / 35 mm rear - enough for visual impact and sharper turn-in, without compromising bump travel or geometry
