Sharpen up the Audi S4/S5 B9’s handling response and steering feel.

Racingline Performance’s beautiful new billet Strut Brace replaces the cheap factory bars to reinforce the bodyshell for a more pleasurable and precise drive.

Modern cars like the B9 Audi run a pretty stiff bodyshell. Load your car hard in the corners though, and the thin, pressed aluminium factory brace won’t be doing much to prevent chassis flex as the strut towers deflect laterally.

The result? Imprecise steering input and a vague, disconnected feeling from the front end.
