The Cusco 18mm rear sway bar for the FD3S RX-7 is an aftermarket rear stabilizer that increases roll stiffness and improves cornering balance. It replaces the factory rear bar to sharpen handling response and reduce body roll under load. Hand-picked for FD3S RX-7 rear fitment, this sway bar integrates with existing mounting points and hardware to tune handling without major suspension surgery.
