Audi A4 Strut Tower Brace - APR - B9 Chassis - Black (2017-2025). This high-strength cross-brace replaces the factory stamped piece to sharpen front-end response and consistency without sacrificing daily comfort.

Engineered for real gains in rigidity, the APR brace uses tubular chromium-molybdenum alloy steel (25 mm OD / 19 mm ID) with billet end caps, TIG welds, and a durable black powder coat. The cross-brace links both strut towers and features an integrated turnbuckle to set preload, reducing flex under cornering and braking for more precise steering feedback. It is a direct bolt-on for the B9 A4 and includes stainless steel hardware.
