It is a direct replacement rear unit that lets you fine-tune damping to suit road, fast road, or occasional trackday use.

Why enthusiasts choose this rear shock

• Sharper handling with reduced squat and bounce for confident traction out of corners.
• User-adjustable damping for a tailored ride and response to match your driving style.
• Twin-tube, gas-charged construction for consistent performance and excellent road feedback.
• Direct-fit rear unit for the BMW E9x platform with OE-style mountings for a clean installation.
• Iconic yellow finish for a smart, performance look.

Our workshop has fitted these to numerous 3 Series builds and customer feedback has been consistently positive. Drivers report a more composed chassis, better high-speed stability, and a more connected feel without making the car harsh. If you are chasing a fast-road setup that still works brilliantly every day, this is the go-to rear damper.
