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

Support the rear suspension towers to reduce chassis twist under load, improving rear-end stability, traction out of corners, and confidence at higher speeds.

$300

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.
