SET OF 4 for FRONT & REAR
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.

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
Please Note:
Price is for each damper you will need to buy 2

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.
- All applications listed on our website are for 2WD models unless otherwise specified as 4WD.
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.

KW Safari Style Coilover Kit – Rise Above!
The KW Safari Style Coilover Kit takes a completely different approach to suspension tuning. Instead of the traditional lowering focus, this system allows for a moderate lift of up to 30 mm, tailored for selected vehicle models. It’s the perfect choice for adventure seekers, overlanders, or anyone looking to upgrade their ride with more ground clearance and a rugged, off-road appearance.
With precisely matched spring and damper rates, the Safari Style suspension enhances off-road capabilities without sacrificing on-road comfort and handling. The height-adjustable system lets you fine-tune the lift to suit your driving style – whether for daily driving, rough backroads, or just that unique elevated look.
Whether you're navigating gravel roads, tackling forest trails, or just want a more confident presence on the street, the KW Safari Style Kit gives you the versatility, durability, and premium quality you expect from KW – engineered and tested in Germany.
Key Features:
• Model-specific lift from approx. 30 mm
• More ground clearance for everyday driving and light off-road use
• Optimized suspension setup for confident handling and comfort
• Continuously adjustable ride height for a personalized setup
• Robust KW components built for durability and performance

Porsche 996 3.4L Carrera
