KW suspension unveils compression and rebound adjustable Variant 3 Dampers for Porsche 911 G-Series

For decades, the Porsche 911 has been a synonym for sports cars. From now on, the suspension manufacturer KW automotive also offers adjustable shock absorbers for numerous historical Porsche 911 (G-Body) model years 1973 – 1989. The dampers or KW suspensions are available in two versions. In addition to the Variant 3, where the standard torsion bars on the front and rear axle are not replaced, also for the track day use, a KW Clubsport variant with racing spring system, adjustable upside down dampers and adjustable top mounts is in preparation. While the Variant 3 dampers are immediately available, the KW Clubsport coilovers for the Porsche 911 will be available to the Essen Motor Show. The V3 dampers, which can be adjusted in compression and rebound, do not require an entry into the vehicle papers. For the KW Clubsport coilovers, a certificate is included. In addition, KW offers various KW Competition racing suspensions for the historic motorsport of the classic Porsche 911. Find out more at



The classic Porsche 911 models have been characterized for decades by a timeless styling coupled with unadulterated sportiness. Everywhere in the world, the “911” is known as a sports car icon. In addition to the Porsche 911 “original model” (1963 – 1973) the Porsche 911 “G Body”, built from 1973 to 1989, enjoys an unimagined popularity. The demand for an individual suspension kit is accordingly high. From now on, in compression and rebound damping independently adjustable KW Variant 3 shock absorbers are available as a suspension complete set in galvanized steel housings for all Porsche 911 (from model year 1974) built from 1973 – 1989. For the first time, it is possible that a suspension kit for the Porsche 911 (G-model) with road approval can be adjusted in driving behavior individually to the own personal driving demand. “Like with every KW suspension development, our adjustable dampers for the Porsche G-model is a vehicle-specific application”, says KW Product Manager Johannes Wacker. „For the development, in addition to driving tests on various test and race tracks, we have also used our 7-post rig. This has the great advantage that we can determine an ideal basic setup with at any time reproducible test cycles, even in advance of our test drives without any subjective influence.”



Lesser body roll on bad roads and a more neutral driving behaviour

With the integrated compression and rebound adjustment click adjusters, it is easy to individually adjust our recommended damper basic setup. For example, with its 16 click setting, the rebound allows to directly take influence on the handling characteristics as well as the driving comfort. With the low speed compression valve, which can be adjusted in twelve clicks, the driving behavior of the Porsche classic can be further increased if desired. For example, a higher compression level on the front axle allows an even more direct steering, and on the rear axle, higher compression damping forces counteract the oversteering. Due to the degressive valve assembly of the preconfigured high speed compression valve, the damping is positively influenced in the case of a sudden driving over street bumps. The wheels can immerse suddenly and this for example prevents the jumping over curbs. The Porsche 911 equipped with the adjustable KW shock absorbers receives a much more direct handling and gets significantly more grip on the rear axle without an increased oversteer. Even the remaining comfort is increased. The great advantage besides a quantum leap in terms of driving dynamics is that the “KW suspension kit” features spindle kits and dampers, so time-consuming strut conversions with replacement cartridges is not necessary. Also, the standard torsion bar springs on the front and rear axle can still be used.



Also right before the market launch: KW Clubsport Coilovers for Porsche 911 (G-series)

For the historic motorsport, KW also manufactures different racing suspensions with independent compression and rebound damping settings for the Porsche 911 G-model, depending on the regulations. Based on this experience, the basis of the KW Clubsport coilovers are a KW racing suspension system, adjustable aluminum Uniball top mounts and 2-way high-performance shock absorbers in upside-down version on the front axle as well as aluminum damper housings on the rear axle. Increased rebound forces ensure a tighter handling and a significantly reduced rolling of the body. So at very high speeds the steering precision is improved at the driving dynamic limit, while on the uneven and wavy road surfaces, a lower rebound stage is advantageous. On the upper damper housing of the KW Clubsport coilover kit for the Porsche 911, the compression stage can be changed with twelve clicks to further increase the driving behavior of the G-model. “Due to our racing springs and the omission of the torsion bar springs, when installing our KW Clubsport coilovers, no specially for racetrack use suitable torsion bar springs have to be retrofitted”, says KW Product Manager Johannes Wacker. The KW Clubsport coilover kit features a certificate and so it can also be used in public road traffic.
