This is a two-in-one upgrade that addresses chassis rigidity and braking performance simultaneously. The lightweight aluminium strut bar reduces body flex for more precise handling, while the integrated stopper braces the brake master cylinder, preventing firewall flex and delivering a more direct and powerful brake pedal feel. It’s one of the most effective and popular upgrades for the RX-8.
- Lightweight, high-rigidity oval-sectioned aluminium strut bar reduces chassis flex.
- Integrated Brake Cylinder Stopper prevents firewall flex for a firmer brake pedal and improved response.
- Increases chassis rigidity for sharper, more predictable handling.
- A direct bolt-on installation with a signature CUSCO blue finish.
You will feel the improvement on the first turn and the first hard stop. The steering becomes more direct, while the brake pedal feels significantly firmer and more responsive, giving you greater confidence and control in all driving situations.
