RIDE HEIGHT ADJUSTABLE

Configure the Ride Height to your needs

KW coilover suspensions, KW height adjustable springs, and KW DLC Air Suspensions allow the suspension to be lowered within the vehicle’s technical limitations. For example, our Street Comfort products allow for a customized ride height setting with mild suspension lowering from 10 – 50 mm, while the Street Performance products allow the maximum technically possible suspension lowering range from 45 – 85 mm, depending on the vehicle. This means that the suspension can be lowered to suit the personal needs of the user and, depending on the product category, a setting ranging from Comfort to Performance can be chosen.

REBOUND ADJUSTABLE TECHNOLOGY

Adjustable Rebound Valve with KW TVR-A (Twin-Valve Rebound Adjustable) Technology.

The rebound stage damping is precisely tuned to the respective vehicle at our in-house drive dynamics test facility, delivered in the middle of the range out of the box. Individual customization can be achieved in 16 precise clicks, allowing you to choose between more comfort or more body control. The two-stage patented TVR-A technology allows the oil to flow through an adjustable, conical low-speed valve during slow piston speeds, while during higher piston speeds the main rebound stage valve opens to handle the flow of large volumes of oil. This provides major improvements in ride comfort without influencing the high-speed.

COMPRESSION ADJUSTABLE TECHNOLOGY (LOW-SPEED)

Adjustable Compression Valve with KW TVC-A (Twin-Valve Compression Adjustable) Technology.

The patented compression valve with TVC-A technology features two separate spring pre-tensioned valves for small and large volume flow. The compression is tuned to the respective vehicle type on our 7-post rig and is delivered in the middle of the range out of the box. With 12 precise clicks the adjustable compression valve can increase or decrease the cross-section in the low speed valve, providing more or less compression damping. In the event of sudden high piston speeds, the low speed spring pre-tensioned needle valve opens to its maximum volume along with the spring pre-tensioned main valve to maximize the volume of oil flow preventing unwanted progressive surges in the high-speed range with its blow-off feature. This makes it possible to support the vehicle body better while still offering more comfort than the conventional valve technology during high wheel travel acceleration. The compression stage damper setting is always supplied in combination with a separate rebound setting, only a truly independent 2-way damper setting allows for true performance optimization.

COMPRESSION ADJUSTABLE TECHNOLOGY (LOW-SPEED & HIGH-SPEED)

Adjustable Compression Valve with KW TVCLH-A (Twin-Valve Compression Low High – Adjustable) Technology.

The compression valve with KW TVCLH-A technology is high-end motor sports technology for the most demanding street and track performance customers. Two separate valves and a two-way adjustable compression valve allow separate compression damping changes in the low and high-speed range. The adjustments are made via two adjustment dials with click increments that feature 16 settings (with 15 clicks) for high-speed and 7 settings (with 6 clicks) of low-speed adjustability. During tuning at the KW driving dynamics test facility, the groundbreaking Variant 4 coilover suspension is tuned to the mid-range setting for the best road performance and provided with an additional recommended setting for occasional track day use. The 3-Way Clubsport coilover suspension is tuned to a mid-level factory setting especially for track day use, with additional range provided for adjusting to a varying degree of vehicle modifications and track conditions. Starting from the factory setting, the damping can be set firmer or softer for low and high-speed. The TVCLH-A technology has a blow-off feature with large cross-section. The resulting amount of low-speed forces create the best support for the vehicle body to keep the tires on the road in the case of wheel-induced high damper speeds (driving over curbs). The separate low and high-speed setting is always supplied with an additional rebound setting, to ensure an independent three-way damper setup.

COMPOSITE SPRING SEAT

Reinventing the way things are done

The KW coilover spring seat, also known as a spring perch, is constructed with a wear-resistant, friction-optimized polyamide composite material encompassing a stainless steel insert. In contrast to the anodized aluminum adjustable spring seats, the polyamide composite material prevents any possible oxidation while the stainless steel insert maximizes strength. In combination with the Inox-Line stainless steel coilover struts, this guarantees the long-term functionality of ride height adjustability.

TRAPEZOIDAL THREAD

The Perfect Height-Adjustable Coilover

In comparison to common coilovers, KW uses a friction-optimized trapezoidal thread which is less sensitive to dirt and requires less force to adjust. Its large cross-section also provides a higher load-bearing capacity.

INOX-LINE

The Truly Permanent Corrosion Resistance

KWs coilover suspension struts are manufactured from high-quality stainless steel that is rust-proof. In contrast to other solutions, Inox-Line coatings will not wear off while adjusting the suspension making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan. Lowering the suspension using the trapezoidal thread in combination with the polyamide composite spring seat guarantees long term usability. Even after years the ride height adjustability is not affected.

RESERVOIR

KW Twin-Tube Technology Knows No Limits

The KW reservoirs provide additional oil and cooling capacity for particularly high force systems. The reservoir, which is filled with low gas pressure, can be fitted anywhere and accommodate the adjustable compression valve to provide more working space inside the damper.

7-POST DRIVE DYNAMICS APPROVED

Testing to the Nth Degree

Used regularly by automobile manufacturers and international race teams, KWs in-house 7-post drive dynamics test facility is utilized to optimally tune KW coilover suspensions according to the design and target group. The 7-post drive dynamics test facility is essential for fine tuning along with actual on-road evaluation on public roads and race tracks. In objective laboratory conditions, which can be reproduced at any time, we work everyday to give our customers the internationally-esteemed KW driving experience.

UNIBAL TOP MOUNT

More Track Performance & Adjustment Options

Depending on the vehicle application, the aluminum unibal top mounts feature a scaled camber adjustment and caster can be optionally adjusted. This means that the camber angle can be set, maximizing the tire contact patch when cornering, making handling even more direct. Please note: increased camber values are only recommended for track day use and may reduce tire lifespan when used on the road.

KW TVR-A Technology

Twin Valve Rebound Adjustable

The rebound stage damping is tuned to suit the respective vehicle at our in-house drive dynamics test facility and comes preset in the middle of the range out of the box. For custom settings the user has 16 precise click positions at their disposal, allowing them to choose between more comfort or more body control.

The two-step, patented TVR-A technology enables the small volume to flow through an adjustable, conical low-speed bypass in the case of slow damper speeds, while in the case of higher piston speeds, the main rebound stage valve opens for the large volume flows. This provides a big improvement in terms of ride comfort without influencing the high-speed range.

OIL FLOW FACTORY SETTING 8 CLICKS

The rebound stage bypass channel is open in a mid-range setting. For slow damper speeds, low oil flows through the bypass in the main valve and the adjustable bypass opening.

The result: a basic setting which conforms to our target parameters for the respec-tive vehicle type and application, and ensures an optimum rebound and deflect ratio.

OIL FLOW DURING HARD REBOUND STROKE

Rebound stage bypass channel is closed. The entire volume of oil is throttled through a setup-specific preset spring valve on the piston. The maximum possible rebound damping forces are achieved.

Result: the sporty/firm tuning of the rebound stage helps to provide even tighter control over vehicle rolling and pitching.

OIL FLOW DURING SOFT REBOUND STROKE

Rebound stage bypass channel is open. The bypass oil quantity is no longer available to the spring valve on the piston, the rebound stage damper forces are reduced in the low-speed range and the lowest possible low-speed rebound damping is achieved.

The result: the low rebound damping increases travel and ride comfort.

HIGH-SPEED CHARACTERISTIC

In the case of high damper speeds and large volume flows the spring-loaded main valve opens in addition. The oil flows through a maximum valve cross section.

The result: the rebound stage setting works in the comfort-relevant low-speed range and has no safety-relevant effect on the high-speed range.

KW TVC-A Technology

Twin Valve Compression Adjustable

The patented compression stage valve with TVC-A technology features two separate spring pre-tensioned valves for low and high volume flows.

The compression stage which is tuned to the particular vehicle type on our 7-post rig is supplied with a mid-range factory setting. With 12 precise clicks the adjustable compression stage valve can increase or decrease the cross section in the low-speed valve to achieve more or less compression stage damping. At the same time, in the case of sud-den high piston speeds, the spring pre-tensioned needle valve and the spring pre-tensioned main valve open to their maximum cross section, utilizing the blow-off feature to prevent undesired progressive power surges in the high-speed range. This allows for improved bracing of the vehicle body while simultaneously offering more comfort than with conventional valve technology in the case of high wheel acceleration. The compression stage damper setting is always supplied in combination with a separate rebound stage setting, as only one independent 2-way damper setting allows for true performance optimization.

OIL FLOW IN BASIC SETTING 6 CLICKS

The spring-loaded adjustable bypass valve is open in a mid-range basic setting. In the case of slow damper speeds the small volume of oil flow runs through the bypass valve. The spring-loaded main valve is closed in the case of slow damper speeds, thus enabling additional low-speed compression damping.

Result: optimum, vehicle-specific tuning with very good bracing against rolling and pitching.
