CUSCO Strut Brace Type OS (Rear) for Mazda RX8 (Series 1 & 2, 2003-2012)

The CUSCO rear Type OS strut brace is a foundational handling upgrade for Mazda RX8 Series 1 & Series 2 models (2003–2012), reinforcing the rear of the chassis to provide a more planted, communicative and predictable rear-end response during cornering.

• Constructed from a lightweight oval-section aluminium bar that offers high rigidity without excessive weight
• Reduces chassis flex during cornering, allowing the rear suspension to maintain more consistent geometry
• Provides a more direct and predictable feel from the rear axle, especially in high-speed transitions
• Direct bolt-on fitment using factory mounting points with no body modification required
• Finished with signature CUSCO blue end plates for a clean, motorsport-inspired appearance in the boot

You will feel greater rear stability, improved mid-corner composure and clearer feedback, giving you the confidence to carry more speed through bends in both Series 1 (2003–2008) and Series 2 (2009–2012) cars.

For a fully balanced chassis package, pair this rear brace with the CUSCO Strut Brace Type OS (Front) and complementary rigidity upgrades like the AUTOEXE Floor Cross Bar.
