The shock absorber for those drivers who prefer a sports suspension but are not particularly interested in lowering the body. Also available in special design complete with reservoir for off-road vehicles.
No risk, more fun
For some people it's important to show what they have, for others it's sufficient to know that they have it. The theme of the discussion here is the sports suspension. The BILSTEIN B6 Sports shock absorber is the ideal solution for drivers revelling in the understatement . The wolf in sheep's clothing snarls, when necessary, but otherwise goes reliably about its work in daily traffic with no lowering of the body whatsoever.

Optimum road holding, enhanced tracking stabilisation and excellent damping force: the BILSTEIN B6 Sports is not only first choice as far as sports tuning is concerned but also in the sphere of safety.

Rear shock absorbers, for cars with PASM electronic damper control (option code: 475)
The PAIR of rear shock absorbers designed to match the factory rear dampers used on the Porsche Boxster Spyder and Cayman GT4 fitted with the optional electronic suspension (PASM / active dampers).
SET OF 2, Rear – left and right shock absorbers.

Fits:
for cars with 'PASM' electronic damper control (option code: 475)

Diagram ref no 1

Because the set replaces both left and right rear dampers together, it restores balanced suspension response and prevents inconsistent damping that can arise when only one side is replaced. Ideal for maintenance, suspension refresh, or performance-driven restoration. It's recommended to replace both shocks at the same time.

Rear shocks wear out over time due to use, heat, and internal component fatigue. Worn dampers lose damping efficiency and can lead to:
• Harsh, unstable ride with excessive bouncing over bumps
• Degraded handling stability, especially under cornering or heavy braking
• Reduced tyre contact and increased tyre wear
• Less predictable rear-end behaviour and reduced driving confidence

Replacing the rear shocks with a new pair restores original ride quality, suspension balance, rear-end stability, and driving engagement.

You should consider replacing rear shocks if:
•  The ride has become noticeably harsh or unsettled over bumps and uneven roads
•  You feel rear-end instability, sway, or reduced grip under braking or cornering
•  The rear suspension shows uneven behaviour or the struts are old/mileage is high
•   You're performing rear suspension maintenance, upgrades, or full refresh
•   You want to restore factory-correct handling and comfort
