Bilstein 24-170680 Rear Damper for BMW Z4 E89

Give your BMW Z4 E89 the composure it deserves. The Bilstein B8 24-170680 rear damper is a short-stroke, gas-charged monotube unit engineered specifically to work with lowering springs and factory sport setups. Expect crisper turn-in, stronger rear-end control and confidence on quick B-roads without ruining day-to-day comfort. It is a direct-fit rear shocker replacement that brings genuine performance car feel to your roadster.

What makes it a standout upgrade

• Shortened stroke matched to lowered ride heights for proper spring control and consistent balance
• Monotube, gas-charged damping for stable, fade-resistant performance on fast road and spirited driving
• Precise control over roll and squat for improved grip and traction out of corners
• Direct bolt-on fitment to OE mounting points on the rear axle
• Tuned for sporty handling while keeping ride quality civilised

We run B8 dampers on our own builds at MJ Modifications and have fitted this rear unit to many customer Z4s. Feedback is consistently positive: tighter rear-end stability, better composure over poor surfaces and a more planted feel when paired with quality lowering springs.
