B4 High Quality direct replacement shock absorbers constructed and finished to Bilstein's high standards often far and above what the car was originally supplied with. They can actually be a performance improvement if replacing plain, none gas charged, oil filled dampers. They dramatically reduce cavitation / oil foaming, thus give for more stable damping forces when driven 'spiritedly'. Some surprising cars come with plain oil filled dampers.

Key Features:
- Twin Tube Damper
- Gas pressurized
- OE damping forces

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.

These replacement Rear shock absorbers are compatible with PASM-equipped cars and include built-in cancellation resistors to eliminate dashboard errors. They effectively bypass the Active Suspension Management system, allowing the vehicle to function as though it has standard suspension installed.

Adjustable suspension kit - Asphalt Rally. 
Front and rear strut assemblies with top mounts

Fits:
Porsche 718 Boxster - 2017 to 2024

This kit is specifically designed for rally-asphalt use. It not only stabilizes the vehicle but also effectively absorbs bumps from uneven road surfaces.

The standard setup includes a wishbone coil over design with 44mm pistons in the struts. These larger pistons allow for a greater volume of shock oil, ensuring durability and preventing shock fatigue, even with prolonged use.

• The Pillowball Top Mount allows for camber adjustments on the front tires, improving cornering performance and vehicle stability.
• The spring rate and damping settings are primarily designed for rally asphalt use.
• This unit includes adjustable ride height and a 36-way damping system to accommodate different road conditions.
• The ride height can be lowered by 60–100mm from the original factory setting, as a reference.
• Even at high speeds, it prevents lateral sliding during sharp turns.
• This product is not suitable for street, rally gravel, or rally snow conditions.
• For any applications not listed, we offer customization to meet specific customer requirements.
• The 3D Pillowball Top Mount also allows for both camber and caster adjustments as an option for customers.

Pillowball Top Mount (fitted to front shock absorber assemblies)
The pillowball top mount allows for camber angle adjustment, improving your vehicle's handling and stability by up to 10%. However, it may produce a slight noise when going over large bumps.

Rear Shock absorber
OE Match rear shock absorber for Porsche 982 Cayman 718 models from 2017 onwards with standard chassis, PR:029. This replacement rear damper fits both left and right rear axle positions and helps restore ride control, handling stability, and rear suspension performance.

Sold individually. 2 required per vehicle if replacing both rear shock absorbers. It is recommended that shock absorbers are replaced as a pair.

Fits:
Porsche 982 Cayman (718) 2017>>
 * cars with Standard chassis (option code: 029)

Diagram Ref No 1

The rear shock absorber controls suspension movement by damping spring oscillation as the vehicle travels over bumps, corners, and uneven road surfaces. A correctly working damper helps keep the rear wheels in contact with the road and supports stable handling, braking, and ride comfort.

Functions
•  Replaces the rear shock absorber
•  Suitable for standard chassis PR:029 applications
•  Fits left or right rear axle position
•  Controls rear suspension movement
•  Helps maintain tyre contact and rear axle stability
•  Supports ride comfort, braking control, and cornering response
•  OE Match replacement for Porsche 982 Cayman rear suspension service.

Why Replace This Part?
Shock absorbers wear over time due to mileage, road impact, heat, fluid movement, and age. A worn rear shock absorber may cause poor ride control, rear axle instability, knocking, fluid leakage, uneven tyre wear, longer braking distance, or reduced cornering confidence. Replacing worn dampers helps restore predictable suspension performance and driving feel.

When to Replace This Part
•   The rear shock absorber is leaking or damaged
•   Rear suspension feels loose, bouncy, or unstable
•   Knocking or noise is present from the rear suspension
•   Rear tyres are wearing unevenly
•   Ride comfort or handling has deteriorated
•   Suspension service or accident repair is being carried out
•   The vehicle has failed inspection due to damper condition

Where it fits on the car
This shock absorber fits on the rear axle suspension assembly of Porsche 982 Cayman 718 models. It can be used on either the left or right rear side.
