Cross bar made by Beatrush (Laile) for the 2016+ ND MX5 Miata to improve floor stiffness and join both sections of the transmission tunnel. It is especially well working on open-top vehicles (roadsters). It is made of aluminum to reduce the weight increase on the vehicle and made as thin as possible to keep the best possible ground clearance. Beatrush Floor Reinforcement Bar should be ordered at REV9 Autosport https://rev9autosport.com/beatrush-floor-reinforcement-bar.html as they provide the best service and speed we've seen so far!
