Cusco Strut Bar OS Rear SE3P RX8

When you're pushing your 2004-2011 Mazda RX-8 through the corners, you want the chassis to feel as solid as possible. This Cusco OS (Over-Steering) Rear Strut Bar is designed to tie your rear suspension towers together, helping to minimize body flex and keep your alignment consistent under load. It's a straightforward way to get a more connected feel from the rear of the car, especially when you're driving it hard.

Cusco builds these strut bars with strong steel tubing, and the end plates are made to bolt directly to the factory mounting points on your RX-8's shock towers. The OS design uses a larger diameter bar, which adds a bit more stiffness compared to smaller bars. Installation is typically a bolt-on affair, meaning no welding or permanent modifications are needed to get this part on your car. You'll notice improved steering response and a more stable feeling when cornering.
