Enhance the handling of your Audi A3, S3, or RS3 8V/8Y with the RacingLine Rear Body Brace, designed specifically for the 8V Sedan 4-door models. This billet and carbon brace reinforces the bodyshell at its weakest point, providing a more precise driving experience. The installation requires no drilling or cutting, and the rear seats remain fully functional.

Modern MQB platform cars feature a stiff laser-welded bodyshell, with rigidity at the front but more flex at the rear, affecting handling during hard use. The RacingLine Rear Body Brace addresses this by connecting crucial hard points with solid billet aluminum mounts and ultra-stiff carbon fiber link bars, significantly stiffening the rear chassis. It fits all Audi A3, S3, and RS3 8V Sedan 4-door models.

By reinforcing the rear strut towers, the brace maintains proper suspension geometry under heavy cornering loads, reducing bodyshell flex and allowing the suspension to function as intended. Despite the added stiffness, the brace does not compromise ride quality or introduce noise, vibration, or harshness into the cabin.

The design allows for simple installation using existing mounting points, with no need for drilling or cutting. It is completely reversible without leaving a trace. The top mounts connect to the rear seat mounts, while the lower mounts lock into the cargo tie-downs, with new luggage tie-downs included. The brace can be tensioned for precise alignment to your car's dimensions.

RacingLine’s low-profile design minimizes impact on trunk space and does not affect rear seat operation, whether the seats are up, down, or removed. The full interior remains intact with the brace installed.

As a track-oriented modification, the brace is designed with weight-saving in mind. It features solid billet CNC 5-axis machined aluminum mounting brackets bonded to ultra-stiff 3K twill carbon link bars. Aerospace-grade T6-6061 Aluminum is used throughout, with an FEA-developed triangulation design to maximize stiffness while keeping weight low.
