KW V1, V2, V3, Clubsport and DDC: Choosing Your KW Kit
KW V1 vs KW V2 vs KW V3 comes down to how much damping you want to adjust. The KW V1 coilover kit has preset damping, the KW V2 adds rebound adjustment, and the KW V3 lets you adjust rebound and compression independently.
The KW V1 vs KW V2 vs KW V3 choice is not about height, because all three set ride height the same way. They also share the same street-kit construction. Past the KW V3 sit the KW Clubsport for track work and the DDC kits with electronic damping. Here is what each one adjusts, who it suits, and how to order the right one for your car.
KW V1 vs KW V2 vs KW V3 at a Glance
KW V1
Damping is preset by KW for your car and is not adjustable. Ride height is adjustable. You set it once and drive.
KW V2
Rebound damping is adjustable. Ride height is adjustable. One adjuster lets you tune how fast the car settles after a bump.
KW V3
Rebound and compression damping adjust independently. Ride height is adjustable. You can firm up one without touching the other.
KW carries TÜV certification on most of these kits. TÜV is Germany's technical inspection and certification system. KW was founded in 1992 as KW Tuning in Murrhardt, Germany. KW brings OE-supplier credibility through its BMW M, Mercedes-AMG and Porsche programs.
How KW Builds Its Street Kits
KW uses twin-tube dampers across the KW V1 to KW V3 range. KW dealer documentation puts it plainly. "KW chooses to use a twin tube damper for its Variant 1-3 product range." KW keeps monotube designs for its motorsport products. The damper bodies on these kits are stainless steel, from KW's Inox-line.
That matters if you have read forum threads that treat twin-tube as a lesser design. It is a different set of trade-offs, not a lower grade. Our guide on monotube vs twin tube dampers walks through heat, stroke and ride feel on both layouts.
Ride height works the same across the three. The threaded body lets you raise or lower the car, and a locking collar holds the setting. Once height changes, camber and toe change too, so book an alignment after you set it.
KW V1: Set It and Drive
The KW V1 is for drivers who want a lower, tighter car and do not want to touch a damper adjuster. KW matches the damping to the car and the spring rate in the kit. You choose the ride height. That is the whole job.
It suits a daily driver that sees the odd spirited back road. It also suits owners who would rather not experiment. Preset damping means no setting can drift out of tune, because there is nothing to turn. If you later want adjustment, plan on a different variant.
KW V2: Rebound Control for Street and Spirited Driving
The KW V2 adds rebound adjustment. Rebound damping controls how fast the spring extends after it compresses. Too little and the car floats and bobs after a dip. More rebound settles the body sooner. Too much slows the wheel's return, and the tire can go light over a crest or a run of bumps.
That one adjuster covers a lot of ground. You can run it softer for a commute on broken pavement, then add rebound before a canyon run or an autocross. For many street builds with occasional track use, a KW V2 coilover kit is where the useful range sits. For the physics behind the clicks, see our guide to damping force. Our guide to adjustable coilovers explains when adjusters earn their place.
KW V3: Independent Compression and Rebound
The KW V3 lets you set compression and rebound on their own. Compression damping controls how hard the damper resists as the wheel moves up. Add it and the car takes a set faster on turn-in, with less dive and squat. Take it away and the car soaks up sharp bumps.
Having both lets you fix one problem without causing another. Say the front bounces after a curb strike. You add rebound and leave compression alone, so the car does not turn harsh. That is why track-day drivers lean toward the KW V3. Always start from the kit's manual setting, change one adjuster at a time, and write down what you did.
KW also builds add-ons for KW V3 and higher kits on selected cars. HLS (Hydraulic Lift System) raises the front axle for steep driveways and speed bumps. Availability depends on the car, so ask us before you plan around it.
KW Clubsport, Competition 3-Way and DDC
KW Clubsport
The KW Clubsport is KW's track-focused two-way adjustable kit. Dealers list separately adjustable rebound and compression, adjustable ride height, and top mounts in the kit. They aim it at track days, HPDE, time trials and autocross. Click counts and mount details vary by car, so check the spec for yours.
KW Competition 3-Way
Beyond the KW Clubsport sits the KW Competition 3-Way. It is KW's motorsport kit, a race-car tool. Call us if you are building one.
KW DDC: ECU and Plug & Play
DDC kits put electronic damping control into a KW coilover. There are two kinds, and they are not interchangeable. DDC Plug & Play is for cars that came with factory adaptive damping. Dealers list it as connecting through the car's original plugs, so the factory controls keep working. DDC ECU is for cars without factory adaptive damping. It uses KW's own control unit and a switch in the cabin, with Comfort, Sport and Sport+ modes.
Our current KW listings sell the KW V1, KW V2 and KW V3. For a KW Clubsport, KW Competition 3-Way or KW DDC kit, call us and we will check what KW builds for your car.
Ordering, Fitment and the KW Warranty
Our KW listings are organized by car, and each one shows which variants you can pick. The 2015 to 2021 VW Golf VII GTI without DCC listing has KW V1, KW V2 and KW V3. So does the 2000 to 2009 Honda S2000 listing. The 2000 to 2006 BMW M3 E46 Coupe and Convertible listing carries all three. So does the 2003 to 2009 Nissan 350Z (Z33) Coupe and Convertible listing. Some cars list only two. The 2020 to 2023 Toyota GR Supra (A90) with electronic dampers lists KW V1 and KW V3 bundles that include the EDC cancellation kit.
Read the title closely. KW splits many cars by drivetrain, body style and factory damping, as the GTI "without DCC" wording shows. Confirm on the product page, or call 1-800-460-9106 with your VIN.
On warranty, KW lists a limited lifetime warranty on the KW V1, KW V2 and KW V3 for the original purchaser. That applies when the kit is bought from an authorized North American dealer and installed per KW's instructions. Warranty and service start with KW's Customer Concern form. KW Clubsport and KW competition products carry different terms. Our guide to coilover warranty support covers the ownership side.
How KW Sits Next to the Other Brands We Carry
KW brings German engineering pedigree, TÜV certification on most kits and OE-supplier credibility. Other brands answer different buyers. BC Racing builds nitrogen-charged monotube kits, with custom spring rates and Swift Springs SPEC-R springs as an upgrade on most fitments. Fortune Auto hand-builds custom-valved kits in Virginia. Öhlins brings DFV valving on its Road & Track kits.
One thing no kit changes on its own is unsprung weight. That is the mass the springs do not carry, such as the wheel, tire, hub and brakes. In the KW V1 vs KW V2 vs KW V3 decision, picking one over another does not move that number. The choice is about damping control and how you drive, which is the heart of good performance suspension.
Frequently Asked Questions
What is the difference between KW V1, KW V2 and KW V3?
Damping adjustment. The KW V1 has preset damping. The KW V2 adds adjustable rebound. The KW V3 adjusts rebound and compression independently. All three have adjustable ride height and use KW's twin-tube street damper in stainless steel bodies.
Is the KW V2 worth it over the KW V1?
If you will use the adjuster, yes. Rebound adjustment lets you run a softer street setting and firm it up for a back road or autocross. If you want to set the height once and never touch the car again, the KW V1 does that job.
Is the KW V3 too stiff for daily driving?
Not by default. Stiffness comes from the spring rate and how you set the dampers. With both adjusters, you can run the KW V3 soft for the street and firmer for a track day. Start from the kit's manual setting and change one adjuster at a time.
Are KW coilovers monotube or twin-tube?
The KW V1, KW V2 and KW V3 street kits use twin-tube dampers, per KW dealer documentation. KW uses monotube designs for its motorsport products. Twin-tube is a design choice with its own strengths in stroke and ride, not a lesser grade.
What warranty comes with KW coilovers?
KW lists a limited lifetime warranty on the KW V1, KW V2 and KW V3 for the original purchaser. The kit must be bought from an authorized North American dealer and installed per KW's instructions. Claims start with KW's Customer Concern form. KW Clubsport and KW competition products carry different terms.
What is the difference between KW DDC ECU and DDC Plug & Play?
DDC Plug & Play is for cars that came with factory adaptive damping. It connects through the original plugs, so the factory controls run the KW dampers. DDC ECU is for cars without factory adaptive damping. It brings KW's own control unit and an in-cabin switch with Comfort, Sport and Sport+ modes.
Can I upgrade a KW V1 to a KW V3 later?
Plan on buying the kit you want rather than converting one. KW sells each variant as its own kit. If you think you will want adjusters, it usually makes sense to start with the KW V2 or KW V3. Call us and we will talk it through for your car.
