The AUTOEXE Floor Cross Bar is a cleverly engineered cabin reinforcement for Mazda RX8 Series 1 & Series 2 models (2003–2012), using existing mounting points to significantly increase chassis stiffness through the rear floor without sacrificing boot usability.
- Connects the left and right sides of the rear floor to reduce flex through the cabin structure
- Delivers a rigidity effect similar to a tower or harness bar while remaining discreet
- Maintains full boot usability and practicality, with no major intrusion into cargo space
- Bolts into high-strength seat mounting positions for a secure, structurally sound installation
You will feel a more solid, cohesive chassis with less twist over bumps and through corners, making the RX8 (2003–2012) feel more stable, responsive and refined at speed.
For best results, combine this Floor Cross Bar with the AUTOEXE Strut Tower Bar and other rigidity upgrades like the CUSCO Rear Strut Brace Type OS for a well-balanced chassis package.
