Ferrari 599 GTB Coilovers: KW V3 Review (2007-2010)

Ferrari 599 GTB coilovers are a harder decision than they look, because every 599 GTB Fiorano built between 2006 and 2012 left Maranello on SCM magnetorheological dampers — the first magnetic-ride system Ferrari ever fitted. Replace them with a conventional coilover and you are not just changing springs and dampers; you are taking a semi-active, manettino-linked electronic system out of a 611 hp V12 supercar. The KW Coilover Kit V3 for the Ferrari 599 GTB (P/N 33642024, $11,244) is the kit we sell for that job, and the reason we recommend it is buried in one line of KW's own application data that almost no listing bothers to explain. The KW Variant 3 is a height-adjustable, twin-adjustable coilover suspension built for the 2007–2010 Ferrari 599 GTB Fiorano that replaces the car's factory SCM magnetorheological dampers with independently tunable rebound and compression damping. This review covers what the kit actually does, what it does to the car's electronics, how far it drops a 599, and what you permanently give up.

Why Ferrari 599 GTB Owners Replace the Factory SCM Suspension

Most 599 owners replace the factory suspension for one of two reasons: the magnetorheological dampers have started to leak, or the car sits too high and cannot be adjusted. Both are structural limitations of the SCM system rather than wear items you can tune around.

SCM — Sospensione a Controllo Magnetoreologico — was Ferrari's first application of magnetic ride, and it was standard equipment on every 599 GTB Fiorano. The dampers are filled with a magnetorheological fluid whose viscosity changes in a magnetic field, so the control unit can vary damping in milliseconds and tie it to the steering-wheel manettino. On paper it is elegant. In practice, on a car now fifteen-plus years old, those dampers are a documented failure point: they weep fluid, and a replacement pair is commonly quoted at around GBP 3,000 (roughly $3,800) before labor. The 599 GTO later received the evolved SCM2 system, but the standard GTB never did.

The second problem is geometry. The 599 is a front-mid-engined V12 grand tourer — a 5,999 cc Tipo F140 C making 611 hp at 7,600 rpm and 448 lb-ft at 5,600 rpm, spinning to an 8,400 rpm redline, sitting on an aluminum spaceframe with a 47/53 front-to-rear weight split and a rear transaxle. It runs 245/40ZR19 fronts and 305/35ZR20 rears, and it weighs roughly 3,700 lb dry and just under 4,000 lb at the curb. That is a lot of car to control, and the factory gives you exactly zero ride-height adjustment. Even the 2009-onward HGTE package — stiffer springs, a stiffer rear anti-roll bar, a lower ride height, a sportier damper calibration and 85 ms F1 shifts instead of 100 ms — is a fixed calibration, not something you can dial.

A coilover solves both at once. It gets you off the magnetic dampers permanently, and it gives you a threaded body and independently adjustable valving. The catch, and the whole reason this article exists, is what the car's electronics do when the SCM dampers disappear.

KW Coilover Kit V3 for the Ferrari 599 GTB: What You Actually Get

The KW Variant 3 is a height-adjustable coilover with independent rebound and low-speed compression damping, and KW catalogs this application in its aluminum-bodied V3 range under part number 33642024 for the Ferrari 599 GTB and GTO (chassis F141), model years 2006 through 2012. At NLP Performance it is $11,244 — which is exactly where the rest of the market sits on this part number.

Two numbers there matter more than the rest. The 10–35 mm lowering range is Ferrari-specific and far more conservative than the 45–85 mm you will see quoted on pages that copied KW's generic V3 line description — a useful tell for whether a listing was written by someone who looked at the actual application data. And the axle load limits (900 kg front, 1,100 kg rear) confirm the kit is valved for the 599's real mass distribution, not adapted from a lighter platform.

Does the KW V3 Trigger a Suspension Warning Light on a 599 GTB?

No — because KW includes the electronic deactivation kit in the box. KW's application data for part number 33642024 states it directly: “Electronic damping control has to be deactivated. Deactivation kit is included in the delivery.” You cannot simply unplug the factory SCM dampers and bolt in coilovers, but you also do not need to buy a separate cancellation module — on this application, KW ships one with the kit.

The module is not software. KW's cancellation kits are coil-and-resistor assemblies that plug into the factory damper harness connectors and simulate the electrical resistance of the OEM adaptive valves, so the car's control unit continues to see the load it expects on that circuit. They mount behind the wheel-house inner liners with clips or cable ties. KW makes the point that adaptive damping on a modern performance car is cross-linked to throttle response, stability control and steering, so an unresolved damper fault does not just light a lamp — it can drop the car into a limp-home program. With the module fitted, KW states that the manufacturer's driving-dynamics programs keep working.

KW has form here across the Ferrari range: its V5 kits for the 812 Superfast (30942013) and F8 Tributo (30942020) are both listed as including electronic damper deactivation, and it sells a standalone cancellation kit (68510480) for the F12 Berlinetta. On the F8, KW notes the cancellation disables only the electronic damper adjustment — the Ferrari Dynamic Enhancer, F1-Trac and the E-Diff all remain active. That is the same architecture at work on the 599.

One honest caveat, because it matters: the “no fault code” behavior above is what KW documents. We are stating KW's engineering position, not the result of an independent teardown, and we have not found a published first-hand 599 install log confirming a clean dash. Ask your installer to clear and re-scan for stored chassis codes after the fit.

How Low Can You Drop a Ferrari 599 GTB?

KW's published range for the 599 is 10–35 mm, or roughly 0.4 to 1.4 inches, front and rear. That is the TUV-tested window, and on a car with the 599's nose you should treat the top of it with respect. The 599 is already a low, long-overhang GT; taking 35 mm out of it turns every driveway apron and speed bump into a decision.

For a car that still gets driven on the road, we would put a 599 nearer the 10–20 mm end of the range, set the rake so the nose is not lower than the tail, and stop there. The gain is not really the drop — it is that you now have a ride height, corner by corner, that you can set on scales. That is the thing SCM never gave you. If ground clearance is the blocker, KW also catalogs a version of this kit bundled with its HLS 2 front-axle lift system (part number 33642224), which is worth asking about before you commit to a static drop.

Setting Up the V3: 16 Clicks of Rebound, 12 of Compression

The Variant 3 gives you 16 clicks of rebound damping and 12 clicks of low-speed compression damping, and the two are independent of each other. That independence is the entire reason to buy a V3 instead of a V2, which adjusts rebound only. Rebound controls how the car settles after the spring is loaded — too much and the chassis packs down over successive bumps; too little and it floats. Low-speed compression controls how the damper resists the initial squat, dive and roll of body movement, which is where a 3,950 lb GT with 448 lb-ft either feels tied down or feels lazy.

Because they do not interact on the V3, you can add compression to sharpen turn-in and load the outside front tire without simultaneously stiffening the rebound stroke and making the car skate over mid-corner bumps. Our advice at NLP Performance is the same one we give every customer stepping onto a 2-way kit for the first time: start soft, change one circuit at a time, and write down the click count before you touch anything.

Where the V3 sits in the KW range

KW's ladder is straightforward. The V1 adjusts height only, with damping pre-tuned by KW. The V2 adds rebound. The V3 adds independent low-speed compression on top of rebound — the fast-road and trackday sweet spot. The V4 splits compression into separate high-speed and low-speed circuits for motorsport valving. The Clubsport line goes further still, with race spring rates and camber-adjustable top mounts. For a 599 GTB that is still a road car with occasional track ambitions, the V3 is the right rung; the Clubsport is more suspension than this car's mission wants.

Installation, Corner Balancing and Alignment

Budget a full day at a shop that knows Ferraris, and plan on going back. There is no published Ferrari-599-specific labor time for a coilover swap, and anyone quoting you one to the tenth of an hour is guessing. What we can tell you is what makes this job longer than a normal coilover install: undertray removal, an aluminum spaceframe that does not forgive careless jacking, wheel lug bolts rather than studs (which makes wheel-off work genuinely fiddlier on a car this heavy), and routing the SCM deactivation modules cleanly behind the wheel-house liners.

The order of operations afterwards is not optional:

1. Install the coilovers and the included deactivation modules; scan for stored chassis fault codes.
2. Set the ride height at each corner with the threaded perches.
3. Roll and settle the car — suspension needs to find its own position before anything is measured.
4. Corner balance on scales, at final ride height, with driver-weight ballast in the seat and a standardized fuel level. Typically 2–3 hours.
5. Then perform a four-wheel alignment. Doing it before corner balancing throws the alignment away.

Have your shop set alignment to Ferrari's published 599 specifications, or to a mild street-performance setup with slightly more negative front camber if the car will see track days. We are deliberately not printing camber and toe figures here — the numbers floating around forums for this car do not agree, and a $11,244 suspension deserves a factory service manual rather than a blog post.

The Honest Trade-Off: What You Permanently Give Up

Fitting the KW V3 means the 599 loses semi-active damping for good. This is the sentence that is missing from every competing listing we looked at, so here it is plainly: once the SCM system is deactivated, the manettino no longer softens the dampers for a bumpy road. Damping becomes purely mechanical. Whatever you set on the 16 rebound and 12 compression clicks is what the car does — in Sport, in Race, in the wet setting, everywhere.

For a lot of 599 owners that is a straight upgrade: a well-set-up 2-way coilover beats a fifteen-year-old magnetic damper that is on borrowed time, and you get ride height and rebuildability that SCM could never offer. For an owner who genuinely uses the manettino's bumpy-road mode on rough surfaces, it is a real loss. Know which one you are before you spend $11,244.

599 GTB Upgrades That Pair With the KW V3

A chassis this sharp exposes whatever is weakest around it. These are the other 2007–2010 Ferrari 599 GTB Fiorano parts we stock at NLP Performance in Tampa, and how they fit into a suspension refresh.

EBC Redstuff front brake pads — the low-dust street option

EBC's 1591 shape is the front pad for the steel-braked 599. Redstuff is the low-dust ceramic compound: EBC rates it at a nominal friction coefficient of 0.5, claims a 60–90% reduction in brake dust versus a standard pad, and — importantly — states on its own product page that it is not for race use. This is the pad for a 599 that gets driven hard on the road and kept clean, not one that sees lapping days.

EBC Yellowstuff front brake pads — the fast-street step up

A note on the listing title, because it confuses people: EBC and most US retailers market DP41591R under the Ferrari 430 Scuderia name, but it is the same 1591 front pad shape — the two cars share the front caliper. Yellowstuff is an aramid-fibre compound rated around 0.42 friction with unusually strong cold bite for a performance pad, and it has been copper-free since 2021. EBC puts its green-fade threshold at 400°C (750°F) and now steers owners toward Bluestuff for dedicated track use, so treat Yellowstuff as fast-street-plus rather than a race pad.

Read this before you order either pad: the 1591 shape is for 599s with iron or steel discs only. If your car was optioned with the Brembo carbon-ceramic package (398 mm front, 360 mm rear) — a very commonly specified option on this car — it uses completely different pads and EBC does not make a CCM-compatible compound. Check your discs first.

BMC replacement panel air filters — a full kit for the V12

The F140 C V12 breathes through two airboxes, and this BMC kit is the full set of two filters rather than a single panel — the detail that catches people out when they cross-shop a cheaper listing. BMC's panel filters are washable and reusable, so on a car this expensive to service they are a one-time purchase. The same part covers the 2022-on Purosangue, which tells you something about how long Ferrari kept that airbox design.

H&R Trak+ 25 mm DRA wheel adaptors — closing the fender gap

Lowering a car changes how the wheel sits inside the arch, and on a 599 the fronts in particular can look sunken once you take 20 mm out of the ride height. H&R's Trak+ DRA adaptors are a bolt-on hub-centric spacer machined from a proprietary alloy with higher tensile strength than 6061-T6 billet aluminum. H&R lists this 25 mm, 5/114.3, 67 mm-bore, 14x1.5 part for the 599 GTB; as always with a bolt-pattern-sensitive part on a low-volume Ferrari, have your installer verify the hub before the wheels come off. Note the 599 uses lug bolts rather than studs, so adaptor length and bolt engagement need to be checked, not assumed.
