718 Cayman GT4 Coilovers: KW Clubsport Off-Season Review

If you track a Porsche 718 Cayman GT4, the smartest suspension money you can spend this winter is a proper set of 718 Cayman GT4 coilovers — and in our Tampa, FL shop the kit that keeps winning that conversation is the KW Clubsport 3-Way. The KW Clubsport 3-way coilover kit (part 39771288) is a road-legal motorsport suspension system for the 2020-and-newer 718 Cayman GT4 (982 chassis) that replaces the factory PASM dampers with three independently adjustable damping circuits: rebound, low-speed compression, and high-speed compression. This review breaks down what “3-way” actually buys you, how it drives, what the install really involves, and why the off-season is the right time to do it.

Why the Off-Season Is the Right Time for GT4 Coilovers

A 3-way coilover swap is not a Saturday-afternoon job, and that is exactly why winter is the window. Installing the KW Clubsport is only step one: the car then has to be corner-balanced on scales, aligned, set to a track-appropriate ride height and camber, and — on a GT4 specifically — have its PASM dampers electronically canceled. String all of that together and you are looking at a multi-day build. Doing it in the cold months means your Cayman GT4 rolls into spring already sorted, instead of burning your first two track days chasing a baseline.

Off-season is also when the good shops have bench time. In our Tampa shop, the GT4 owners who book their suspension work in December and January get the unhurried setup session a 3-way damper deserves — the shock dyno numbers, the corner weights, and the seat time to actually learn the clicks. Rush a $12,000 coilover install into a race-week panic and you waste most of what you paid for.

KW Clubsport 3-Way Coilover Kit: Full Review

KW developed the Clubsport line on the Nurburgring Nordschleife and a 7-post shaker rig, using the same damping technology that shows up in 24-hour endurance cars. The construction is KW’s inox-line stainless steel, which the company markets as 100% corrosion-resistant with an effectively unlimited service life — a genuine advantage over painted steel bodies for a car that sees salt-tinged winter storage or wet paddock use. The dampers are fully rebuildable, so a hard-used set can be freshened rather than thrown away.

Setup range is the other reason this kit belongs on a track-focused GT4. Ride height is independently adjustable front and rear through the threaded strut bodies, so you can drop the car for a lower center of gravity and then fine-tune rake to balance the chassis. Combined with the camber built into the unibal top mounts, that gives you the three levers a serious track alignment needs — ride height, corner weight, and camber — all mechanical, all repeatable, and all independent of the electronic PASM system the kit removes. It is the difference between a GT4 that is merely lowered and one that is genuinely dialed for the conditions you run.

What Does 3-Way Adjustable Actually Mean?

3-way adjustable means the damper gives you three independent controls instead of the single all-in-one knob on an entry coilover. On the KW Clubsport that is rebound, low-speed compression, and high-speed compression — and compression is genuinely split into two circuits by KW’s patented two-valve control on the reservoir, not just a soft-to-firm range. In practical terms:

• Rebound (TVR-A adjuster, 16 clicks): controls how fast the wheel extends after a bump or through corner exit. Dial it to tune mid-corner grip and how the car settles onto the tires.
• Low-speed compression (purple dial, 6 clicks): governs body control during driver inputs — braking dive, turn-in roll, throttle squat. This is the knob that changes how the GT4 feels under your hands.
• High-speed compression (gold dial, 14 clicks): handles sharp, fast shaft movement — curbs, rumble strips, sudden pavement changes — so the car stays composed over kerbing without punishing the ride on smoother sections.

The reason that matters on a 718 Cayman GT4 is separation. A 2-way coilover splits compression from rebound; a 3-way further splits compression into low- and high-speed, so you can add high-speed compression to survive aggressive curbs at a track like Sebring without also stiffening the low-speed behavior that dictates steering feel. That is tuning resolution a factory PASM system simply cannot offer.

How It Drives on Track and on the Street

The single biggest change GT4 owners notice is steering precision. The Clubsport uses solid aluminum unibal (spherical-bearing) top mounts in place of the factory rubber, which removes deflection under load and provides camber adjustment where applicable. Turn-in gets sharper and the front axle reports the road more honestly — the car feels like it lost a layer of insulation between your hands and the contact patch. On a purpose-built track weapon like the GT4, that clarity is the whole point.

The honest tradeoff is noise. Those same unibal mounts transmit more road and impact noise than rubber, so on the street you will hear and feel more of the pavement, and the bearings want periodic inspection as they age. This is a motorsport-oriented coilover; it rewards a car that gets driven hard and is a little much for a Cayman that only sees grocery runs. For a GT4 that lives for track days, the added feedback is a feature, not a flaw.

2020+ Porsche 718 Cayman GT4 (982): Specs and Why Owners Upgrade

The 718 Cayman GT4 is powered by a 4.0L naturally aspirated flat-six making 414 hp at 7,600 rpm and 309 lb-ft at 5,000 rpm, spinning to an 8,000-rpm redline. With the standard 6-speed manual it hits 60 mph in about 4.2 seconds and weighs roughly 3,199 lb. From the factory it rides on track-tuned PASM adaptive dampers sitting 30 mm (about 1.2 in) lower than a base 718, with rear helper springs and staggered 245/35ZR20 front and 295/30ZR20 rear tires.

So why change a car Porsche already engineered for the track? Because even an excellent PASM setup is a fixed compromise. It gives you a firm and a firmer mode, not the ability to independently trim high-speed compression for curbing or corner-balance the car for your weight and fuel load. Serious HPDE and club-racing owners want three things PASM cannot deliver: independent damping circuits, motorsport-grade ride-height and corner-weight control, and rebuildable dampers that survive a full season of abuse. The KW Clubsport delivers all three while staying road-legal.

Installation, PASM Delete, and Corner-Balancing

Fitting the coilovers is the easy part; setting them up is the job. Because the KW Clubsport replaces the GT4’s electronic PASM dampers with mechanical adjustable units, you also need a KW PASM cancellation kit to clear the dashboard warning light and stop the car logging fault codes. Budget for that up front — it is not optional on a 982 GT4.

Once the dampers are on, the car has to be corner-balanced (cross-weighted on scales) and then aligned, in that order. Adjusting ride height changes camber, toe, and caster at every corner, so a proper setup means setting height, corner-balancing to your driving weight, then dialing the alignment to a track spec. As a rough guide, plan on about $150–$300 for install labor and another $150–$300 for a performance alignment, with corner-balancing billed separately and only offered by shops that have scales. In our Tampa shop we treat the whole thing as one appointment so the numbers are right the first time — another reason the off-season, with its open bench time, is the moment to book it.

Is the KW Clubsport Worth It for a 718 Cayman GT4?

For a GT4 that sees genuine track use, yes. The all-in cost lands north of $12,000 once you add the PASM kit and setup, which is real money — but you are buying the top of KW’s road-legal ladder, not a mid-tier compromise. If your Cayman is street-focused with the occasional canyon run, a simpler two-way or a quality lowering-and-damper package makes more sense and you can browse the full range in our suspension collection. If the GT4 is your track car and you want to extract every tenth, the Clubsport 3-Way is the answer, and the off-season is when to install it.
