KW V3 Coilover Review: 2008-2015 Mitsubishi Evo X (CZ4A)

If you own a 2008-2015 Mitsubishi Lancer Evolution X, the fastest way to unlock the chassis is a set of KW V3 coilovers. The Evo X left the factory as one of the sharpest all-wheel-drive sedans ever built – a 291-horsepower 4B11T turbo four routed through Mitsubishi’s Super All-Wheel Control (S-AWC) with Active Yaw Control – yet the stock dampers and soft-ish sport springs still leave grip and body control on the table. At NLP Performance in Tampa, FL, the KW Variant 3 (part number 35265017, $3,984) is the coilover our Evo customers ask for by name, and this review breaks down exactly what it does, how it differs from cheaper kits, and the sway bars, camber arms and endlinks that complete the setup.

Why the Evo X Chassis Rewards a Real Coilover Kit

The Evo X (chassis code CZ4A) is the tenth and final generation of the Lancer Evolution, sold in the U.S. from 2008 through the 2015 Final Edition. Under the hood is the 4B11T, a 2.0-liter turbocharged inline-four rated at 291 hp at 6,500 rpm and roughly 300 lb-ft of torque in U.S. GSR and MR trim. That power reaches the ground through S-AWC, which blends an Active Center Differential (ACD), Active Yaw Control (AYC) rear diff, and Sport ABS to shuffle torque and rotate the car mid-corner. GSR cars use a 5-speed manual with conventional KYB struts; MR cars use the 6-speed Twin-Clutch SST dual-clutch with Bilstein dampers and Eibach springs.

Here is the catch: the Evo X weighs roughly 3,400 to 3,500 lb, and a lot of that mass sits high and forward. The factory sport suspension is genuinely good for a showroom car, but it is a compromise tuned for ride quality and warranty-friendly wheel travel. Push a stock Evo X on a track day and you feel it – nose-dive under braking, roll on turn-in, and a ride height that leaves a fender-gap you could lose a fist in. A quality coilover kit fixes all three at once: it drops the center of gravity, adds damping control to keep the tires planted, and gives you the adjustability to corner-balance an AWD car that lives and dies by even weight distribution across all four contact patches.

KW Variant 3 Coilovers for the Evo X: Our Review

The KW Variant 3 is a fully height-adjustable, dual-adjustable-damping coilover kit engineered and manufactured in Germany. On the Evo X it is the flagship of KW’s street/track line – above the fixed-damping Variant 1 and the rebound-only Variant 2 – and it is the kit we reach for when a customer wants one suspension that does everything from a daily commute to a competitive autocross run.

The Evo X kit (part number 35265017) rides on 455 lb/in front and 340 lb/in rear springs, delivers a continuous lowering range of 0.9 to 2.1 inches up front and 0.6 to 1.7 inches in the rear, and ships with a TUV certificate, a spanner wrench and adjustment instructions. In practice, the V3 transforms how the Evo X puts power down. Because you can firm up compression damping to fight squat and dive without over-stiffening rebound, the car stays flatter under hard braking into a corner and settles faster on corner exit – exactly where an AWD Evo wants to hook up and launch. KW’s own engineering literature notes that separating the two damping circuits shortens braking distances and reduces pitch and roll during load changes such as evasive maneuvers, cornering and acceleration. On a car that relies on all four tires working together through S-AWC, that added control is worth real lap time.

What Makes the KW V3 Different From a Budget Coilover?

The KW V3 is defined by its patented TVR-A and TVC-A twin-valve damping technology, which gives you 16 clicks of rebound adjustment and 12 clicks of low-speed compression adjustment, set separately and independently of each other. That matters because rebound and compression do different jobs: rebound controls how the spring releases its energy (body control and grip on corner exit), while compression controls how the damper reacts to bumps and load transfer (ride quality and squat/dive). A cheap single-adjustment coilover forces one knob to compromise both. On the V3 you dial compression for the surface and rebound for the spring rate, then leave the setup optimized instead of fighting itself. (High-speed damping is preset by KW’s engineers, so you cannot accidentally upset the safety-critical range.)

Construction is the other half of the story. The V3’s INOX-LINE struts use a twin-tube damper inside a stainless-steel housing, and the ride-height collar rides on KW’s dirt-resistant trapezoid thread with a polyamide-composite locking ring and a stainless insert. That is why the threaded bodies keep adjusting freely years into salty, rainy, road-grime service – a real problem on painted-steel budget kits that seize up. KW pairs the dampers with elastomer spring elements to keep the ride livable, and the whole kit is engineered and built in Germany and backed by KW’s limited lifetime warranty (unlimited mileage, with authorized-install conditions). This is a lifetime-of-the-car component, not a season-long track consumable.

Ride Height, Damping and Corner Balancing on an AWD Car

The V3’s threaded stainless bodies let you set ride height across a broad, continuous range – roughly 0.9 to 2.1 inches at the front axle and 0.6 to 1.7 inches at the rear – so you can choose an aggressive track rake or a milder street drop that keeps the front lip off the driveway. Because ride height is set at the lower spring perch rather than by preloading the spring, you keep full damper travel and a comfortable ride even when the car sits low – something a lowering-spring-only setup cannot do.

Corner balancing is where an adjustable coilover earns its keep on the Evo X. Because S-AWC distributes torque across all four wheels, uneven corner weights make the car push in one direction and rotate in the other. Setting each corner’s height on a set of scales evens out the diagonal weight so the AWD system has a symmetrical platform to work with. Evo X owners who run the V3 consistently describe the same result: a flatter, more predictable car that rotates on throttle and stops nose-diving under threshold braking, without the punishing ride that scares people away from coilovers.

Complete the Handling Package: Sway Bars, Camber Arms and Endlinks

Coilovers set the platform; anti-roll bars tune the balance. Adding adjustable sway bars to the Evo X is the single most cost-effective way to fine-tune understeer and oversteer – stiffen the rear bar to help the car rotate, soften it to add mid-corner stability. And any time you lower an Evo X, the rear suspension gains negative camber that eats tires and dulls turn-in; adjustable rear control arms with zero-compliance bearings bring camber back into spec (some listings label these toe arms). Here are the parts we pair with the V3 for a complete, corner-worked CZ4A.

Prefer to buy your bars individually or match a heavier rear rate to your driving style? We stock the Whiteline 27mm heavy-duty adjustable bars separately – a front bar (BMF55Z, $230.63) and a matched rear bar (BMR84Z, $218.75), each with 3-point (three-hole) blade adjustment so you can dial in maximum roll stiffness at the track and back it off for the street. Whiteline mounts them on its synthetic elastomer bushings, which ride like rubber at low speed but firm up under cornering, braking and acceleration loads, and resist oil, ozone and weather.

The Hotchkis heavy-duty rear endlinks (25440R) are the small part that makes the bigger parts work. They use three-piece, PTFE-lined half-inch heim joints, CNC-machined 6061 aluminum sleeves and grade 10.9 hardware, so a stiffer sway bar transmits its full input to the chassis instead of losing motion through soft, flexing stock links – and because they are length-adjustable, they help when you corner-balance the car.

Installation, Alignment and Fitment Notes

A KW V3 coilover install on the Evo X is a straightforward bolt-in that a competent DIYer can complete in roughly 4 to 6 hours with hand tools, pre-assembled coilovers (no dangerous spring compressor needed), and a jack and stands. Budget most of your time for setting corner heights. The one non-negotiable step: get a professional alignment afterward, because lowering the CZ4A changes camber and toe on all four corners. If you are chasing lap times, have the shop corner-balance the car on scales at the same time – it is the difference between a car that feels balanced and one that fights you. This is exactly the kind of setup work our team handles at NLP Performance in Tampa, FL.

All of the parts in this guide are a direct fit for the 2008-2015 U.S. Evo X (GSR and MR; the sway bar kit and camber arms cover 2008 and 2010-2015). Double-check your exact trim and year on each product page before ordering, and remember that the Ralliart-badged Lancer uses different rear geometry – the Whiteline camber arms listed here are for the Evolution X, not the Ralliart.
