Racingline Carbon Fibre Rear Body Brace for Audi A3/S3/RS3 (8V) & RS3 (8Y) Saloon/Sedan

Racingline Carbon Fibre Rear Body Brace for Audi A3/S3/RS3 (8V) & RS3 (8Y) Saloon/Sedan

Sharpen the handling of your Audi A3, S3, or RS3 Saloon with the Racingline Carbon Fibre Rear Body Brace. Designed specifically for the 4-door Saloon/Sedan body shape, this brace reinforces the rear of the chassis where flex is most noticeable, giving you crisper turn-in, better composure under load, and a more connected feel behind the wheel.

Why a Rear Body Brace Makes a Difference

Modern cars built on the MQB platform are stiff at the front, but the rear of the bodyshell can still flex during hard cornering. That flex disturbs your suspension geometry, blunting the response of your dampers and springs, particularly if you’ve already fitted stiffer suspension. The result is handling that feels less precise than it should.

By locking the rear strut towers and key chassis mounting points together, the Racingline brace stiffens this weak area significantly. It’s the same principle Volkswagen used when fitting a factory rear brace to the Golf Clubsport S, just applied with higher-grade materials and a cleaner installation.

Engineered for Strength and Light Weight

The brace uses solid billet aluminium mounts joined by carbon fibre link bars. Carbon fibre is exceptionally rigid for its weight, so you get maximum stiffness without adding unnecessary mass to the rear of the car. It’s also a genuinely good-looking piece of engineering, which is a bonus given how much of it remains visible in the boot.

Importantly, the added stiffness doesn’t come at the cost of ride comfort. There’s no extra noise, vibration, or harshness transferred into the cabin, just a noticeable improvement in how the car responds when you push it.

Clean, Reversible Installation

The brace bolts to existing body mounting points, so there’s no cutting or drilling required. Interior trim does not need to be permanently removed, and the modification is fully reversible if you ever wish to return the car to standard. It’s also compatible with the rear seats in place, folded down, or removed entirely, so you keep full use of the boot and interior.

What You’ll Notice on the Road

• Sharper steering response and turn-in
• Improved stability and composure through fast corners
• Better feedback from the rear of the car
