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.

Shock absorbers with top mounts and fitting kit for the front suspension of Porsche 993 C2 and C4 models, supplied as a matched kit for both sides to support correct fit and function.
What This Product Does This kit refreshes the front shock absorber upper mounting area on Porsche 993 models, replacing key hardware and mount components so the front dampers are correctly located and supported.
Functions
- Locates the top of the front shock absorber securely in the body
- Supports the front suspension under braking, cornering and bumps
- Replaces aged mounting components in one matched kit
- Helps reduce knock and play from worn top mount hardware
- Supports correct suspension geometry and damper movement
Symptoms of Fault
- Knocking or clunking noises from the front suspension over bumps
- Creaking when steering, especially at low speeds
- Vague or unsettled steering feel
- Harsh impact noise from the top of the suspension
- Uneven or accelerated front tyre wear linked to suspension movement
Why Replacement Matters
Front suspension hardware on older Porsche models can deteriorate with age, mileage and repeated load cycles. Rubber, bearings and fasteners at the top mount can harden, wear or loosen, leading to noise, imprecise steering feedback and additional stress on the dampers. Replacing the full set of upper mounting components together helps ensure the front shocks can operate as intended and reduces the likelihood of reusing tired parts during suspension work.
