Audi S5 Strut Tower Brace - APR - B9 Chassis - Black - 2018–2025: a high‑strength, adjustable brace that increases rigidity and sharpens steering on your B9 S5.

APR replaces the factory stamped brace with tubular chromium‑molybdenum steel in a black powder coat. The cross‑brace links both towers, and a turnbuckle sets preload to curb flex under cornering and acceleration. Billet end caps, TIG welds, and stainless hardware deliver durability. Compatible across B9 A4/A5, S4/S5, and RS4/RS5, and tuned to maintain daily comfort with no added NVH.

Features

• Cr‑Mo tubular construction (25 mm OD / 19 mm ID), black powder coat
• Adjustable preload via center turnbuckle
• Integrates strut towers and firewall
• Direct bolt‑on; no cutting required
