Bilstein B16 PSS9 Coilover Kit for Mazda RX-8 - 48-110297

Damping controls how quickly the suspension moves. A combined control changes compression and rebound together. Separate controls let you adjust them independently. More controls mean more setup choices; they do not guarantee a better ride.

A spring-rate pair normally lists front, then rear. Keep the unit shown on the kit specification: kgf/mm (often written kg/mm) and N/mm are different units. The right rate depends on the car and setup. Ask us before choosing a custom rate or changing springs.

Some kits reuse the original mounts; others include rubber or pillowball mounts. Camber adjustment depends on the mount and suspension layout. Check the exact configuration rather than assuming the representative photograph shows every included part.

If your car has factory electronic damping, tell us before ordering. The kit may retain that function, require an additional compatible cancellation solution, or have a specific exclusion. The correct answer depends on the vehicle and exact kit.

Lowering ranges and required parts vary by application. Read the kit notes and use a qualified installer. Changes to ride height affect alignment, so ask your installer to check the setup after installation.

Identify the component before asking for a replacement. Include the kit code, serial or batch marking and affected corner. The illustration names common external parts; the exact hardware and service route depend on this kit.
