Front suspension / Audi B9 / A4 & S4 & RS4 (B9) / A5 & S5 & RS5 (B9)

Do you want to sharpen the handling response and improve the steering feel of your Audi B9?
The new billet Strut Brace from RacingLine Performance replaces the flimsy factory brace and stiffens the chassis to provide a more engaging and precise driving experience.

⚙️ The problem with the factory brace

Modern B9 models have a relatively stiff body, but under heavy cornering loads, the thin, stamped aluminum OEM brace fails to limit lateral deflection of the strut towers.
The result is often:

• inaccurate steering input

• a "rubbery" feel

• a weaker connection with the front end

🔩 Billet solution for maximum stiffness

• Massive billet aluminum construction – significantly stiffer than factory

• Connects and strengthens the front strut towers

• Maintains proper suspension geometry under high lateral loads

• Ensures consistent and predictable steering response

🔇 No compromise on comfort (NVH free)

Despite the increased stiffness:

• ❌ no additional noise

• ❌ no vibrations

• ❌ no ride degradation

The improvement in handling comes without any negative effect on daily comfort.

🧰 Easy and fully reversible installation

• Installation is simple and quick

• Uses factory mounting points

• ❌ No drilling

• ❌ Fully reversible

✨ Premium look in the engine bay

In addition to the functional benefits, the RacingLine Billet Strut Brace also adds a finished, premium look to the engine bay – exactly the level that the Audi B9 deserves.
