The Hyundai Veloster N has earned a reputation as one of the most rewarding hot hatches on the market, blending a sharp chassis, a potent turbocharged engine, and an engaging manual or dual-clutch transmission. Yet even the most well-engineered factory suspension involves compromises to satisfy a broad range of drivers and road conditions. Upgrading to KW coilovers transforms the Veloster N’s dynamics, offering finer control over ride height, damping, and overall balance. This article breaks down the investment required, provides a detailed installation guide, and explains the tangible handling benefits you can expect on both the street and the track.

Understanding KW Coilovers

KW Automotive, a German manufacturer with decades of motorsport experience, produces several series of coilovers suited to different performance goals. For the Veloster N, the most popular options are the KW Variant 1 (V1), Variant 2 (V2), and Variant 3 (V3). Each uses a stainless steel body to resist corrosion and a threaded spring perch for ride height adjustment. The key differences lie in damping control:

  • KW V1: Fixed damping rates preset at the factory. Ride height is adjustable but rebound and compression are non‑adjustable. This is the entry‑level choice for drivers seeking improved stance and sharper turn‑in without the complexity of tuning.
  • KW V2: Separate rebound damping adjustment (16 clicks) while compression remains fixed. This allows fine‑tuning of how the suspension settles after a bump, ideal for balancing comfort against track performance.
  • KW V3: Independent adjustment of both rebound and low‑speed compression damping (each with 16 clicks). The V3 provides the widest tuning range, enabling precise control over body roll, grip, and ride harshness. It is the preferred choice for serious track enthusiasts.

All KW coilovers for the Veloster N are TÜV‑certified, meaning they undergo rigorous testing for safety and durability. The springs are made from high‑tensile cold‑wound steel that resists sagging over time. Build quality is a key differentiator: KW uses a proprietary underground coating and stainless steel to prevent corrosion, a notable upgrade over powder‑coated steel found in many cheaper coilover kits.

Cost Breakdown for a Veloster N KW Coilover Upgrade

The total cost of installing KW coilovers exceeds the kit price. Understanding each component of the expense helps budget accurately and avoid surprises.

Coilover Kit Price

Retail prices for KW kits fluctuate with market conditions and the chosen variant:

  • KW V1: $1,500 – $1,700
  • KW V2: $1,800 – $2,100
  • KW V3: $2,200 – $2,600

Prices vary by vendor, seasonal sales, and whether the kit includes top mounts or requires reuse of factory hardware. Some dealers bundle installation kits with new strut mounts and bump stops, which may be wise for higher‑mileage vehicles.

Installation Labor

Professional installation at a reputable shop typically runs $400–$700. The range depends on geographical labor rates (e.g., $100–$150 per hour in many metropolitan areas) and whether the shop performs corner balancing and alignment afterward. A smart DIY installer can save this cost, but must account for the investment in tools such as a spring compressor, torque wrench with appropriate sockets, and jack stands.

Alignment and Corner Balancing

After any suspension change, a four‑wheel alignment is essential to prevent uneven tire wear and maintain predictable handling. Expect $80–$150 for a standard alignment. If you plan to exploit the full performance on track, corner balancing adds another $200–$400. This process measures the weight on each wheel and adjusts ride height and preload to balance corner weights, maximizing grip through turns. Many track‑oriented owners consider corner balancing a mandatory step after installing adjustable coilovers.

Additional Parts and Hidden Costs

Reusing worn suspension components can compromise the new coilovers. Common supplementary expenses include:

  • Strut mounts & bearings: $100–$200 (replacing them prevents clunking noises)
  • Adjustable sway bar end links: $100–$200 (to restore proper sway bar geometry at lowered ride heights)
  • Bump stops or dust boots: $30–$60 (if not included with the kit)
  • Shop supplies and disposal fees: $20–$50

In total, a budget‑minded owner should plan for $2,000–$3,500 for a complete, properly installed KW coilover system. While that figure may seem steep, it positions the Veloster N in the same league as cars costing two or three times as much when it comes to chassis composure.

For perspective, compare KW coilovers to alternatives like Bilstein B16 ($2,300–$2,800) or Ohlins Road & Track ($2,800+). KW’s stainless steel construction and wide availability of tuning expertise make it a strong value proposition.

Installation Tips for KW Coilovers on the Veloster N

Installing coilovers is a weekend job for a moderately experienced DIY mechanic, but attention to detail is critical. These tips will help you avoid common mistakes and achieve the best possible result.

Preparation and Tools

Before lifting the car, gather the following:

  • Floor jack and four jack stands
  • Torque wrench (10–250 N·m range)
  • Metric socket set (10mm, 12mm, 14mm, 17mm, 18mm, 21mm, 22mm)
  • Spring compressor (if reusing factory top mounts)
  • Pry bar or pickle fork for disconnecting sway bar links
  • Penetrating oil (e.g., WD‑40 or PB Blaster) for rusted hardware
  • Trim removal tools for accessing rear shock upper mounts
  • Clean rags and safety glasses

Work on a level concrete floor. Measure the current ride height from the center of the hub to the fender edge on all four corners before removal—this gives a baseline for setting the new coilovers.

Removing the Factory Suspension

The front struts on the Veloster N require removal of the three top‑mount nuts under the hood, the lower pinch bolt connecting the strut to the knuckle, and the brake line bracket. Always support the lower control arm to prevent the half‑shaft from separating. For the rear, you must unclip the interior trim panels to access the upper shock mount. Remove the lower bolt securing the shock to the trailing arm and the sway bar end link if attached. Label all fasteners and place them in separate bags.

Critical safety check: Never unscrew the large center nut on a strut without using a spring compressor. The spring can eject with lethal force.

Assembling and Adjusting the KW Coilovers

Each KW coilover is pre‑set from the factory with a baseline ride height. For a Veloster N, a drop of 1.0–1.5 inches is common for daily driving while maintaining acceptable ground clearance. To adjust ride height, turn the lower spring perch with the supplied spanner wrenches. Do not use the damper body nut for height adjustment—that nut secures the internal cartridge. Always adjust via the threaded collar on the spring perch.

Set the damping on the V2 or V3 as follows before installation: start with the recommended settings from the KW manual (typically 8 clicks from full stiff for rebound on V2, and 8 clicks for rebound and 6 clicks for compression on V3). These provide a safe baseline for the test drive. You can fine‑tune later.

Installation Sequence

  1. Install the front coilovers first. Swap the factory top mount onto the KW strut body if required (for V1 and V2 kits that do not include camber plates). Torque the center nut to manufacturer specifications (typically 80–100 N·m).
  2. Reattach the strut to the knuckle and lower control arm. Snug all bolts but do not fully tighten until the car is on the ground with suspension loaded.
  3. Repeat for the rear coilovers. The rear shocks are easier to install if you compress the suspension slightly with a jack while guiding the upper bolts into place.
  4. Once all four corners are in place, lower the car to the ground. Bounce the suspension several times to settle the bushings, then torque all fasteners to factory values. This step prevents premature bushing wear and suspension noise.
  5. Set the final ride height. Measure from the hub center to fender edge and adjust the perches equally for a balanced look. A typical starting point for a street‑focused Veloster N is 13.5 inches front, 13.0 inches rear (from hub to fender).

Post‑Installation Alignment

Even if you only changed ride height, the camber and toe angles will shift. Drive to an alignment shop with the coilovers set to your desired height. Specify a performance alignment with increased negative camber (about −1.5° to −2.0° front, −1.0° to −1.5° rear) to improve cornering grip. Toe should be set to zero or very slight toe‑in for stability. A poor alignment will ruin tire life and can mask the true handling benefits of the KW coilovers.

Handling Improvements with KW Coilovers

Once the coilovers are installed and aligned, the change in the Veloster N’s behavior is immediately noticeable. The improvements stem from three core mechanical changes: lower center of gravity, stiffer spring rates, and controlled damping.

Reduced Body Roll

The factory suspension allows considerable body roll during aggressive cornering, which delays weight transfer and reduces available grip. KW coilovers, even in the V1 fixed‑damping variant, stiffen the roll stiffness significantly. A typical KW spring set for the Veloster N uses linear rates around 50–60 N/mm front and 55–65 N/mm rear, versus the OEM progressive springs which are softer initially. With the V3’s compression adjustment, you can tune out nearly all body roll while keeping the ride livable. Real‑world measurements show a reduction in lateral body roll from around 4 degrees stock to under 2 degrees at similar cornering speeds.

Improved Grip and Traction

Lowering the ride height lowers the car’s center of gravity, which reduces weight transfer and keeps the tires more evenly loaded through turns. The ability to add negative camber (up to −2.5° front with camber plates, if your KW kit includes them or you add adjustable top mounts) further improves the tire contact patch during cornering. Drivers report an increase in lateral grip of approximately 0.05–0.10 g on standard street tires when the coilovers are properly tuned. For track use, that margin can mean several seconds per lap on a 2‑kilometer circuit.

Acceleration traction also improves because the rear suspension stays flatter under power. The KW dampers reduce wheel hop, which is a known issue with the Veloster N’s factory setup on aggressive launches. A forum post at VelosterN.org – KW V3 Track Review documents a consistent lap time improvement of 1.2 seconds at a local track after the upgrade.

Ride Quality – The Trade‑Off

Stiffer springs and firmer damping inevitably change ride quality. However, KW’s damping calibration is known for its ability to suppress low‑speed compression (potholes, expansion joints) without transmitting excessive harshness. In the V3, nine clicks of rebound and seven clicks of compression from stiff provide a firm but compliant daily drive. At maximum stiffness, the ride becomes too jittery for public roads but delivers razor‑sharp response on smooth track circuits. The V1 and V2 are more forgiving because they lack independent compression adjustment. Most owners find a middle setting that retains an acceptable level of comfort for commuting while offering vastly improved control.

Customizability for Different Driving Styles

The ability to tune the suspension is perhaps the greatest advantage of KW coilovers. A driver can soften the dampers for a long highway trip, then stiffen them at the track without any tools (on V2/V3) except your fingers for the adjustment knobs. The ride height adjustment also allows the enthusiast to dial in a subtle for a more aggressive stance, but maintain enough ground clearance for speed bumps and steep driveways—usually 3–4 inches of ground clearance at the lowest point is a safe minimum. For the Veloster N, many KW users set the front 5 mm higher than the rear to maintain stability under heavy braking.

Long‑Term Considerations and Maintenance

KW coilovers are built to last, but they are not maintenance‑free. The following points ensure many years of trouble‑free service.

Inspection and Cleaning

Salt and road grime can accumulate on the damper shaft and spring perches. After winter driving or off‑road excursions, spray the shafts with a silicone lubricant and wipe clean. The adjustable knobs should be exercised periodically to prevent seizing. If you track the car frequently, plan on a damper rebuild every 30,000 miles or two seasons—KW offers a factory rebuild service with a quick turnaround.

Spring Sag and Ride Height Creep

Cold‑wound springs are resistant to sagging, but if you notice one corner of the car sitting lower after months of use, the spring may have settled. You can adjust the perch to compensate. More often, ride height changes occur because the locking collars loosed. Use a thread‑locking compound (e.g., Loctite 242) on the adjustment rings after setting final height.

Impact on Other Components

Lowering the car changes suspension geometry. The lower control arms move upward, which alters roll center and can increase bump steer. Installing adjustable end links for the front sway bar and possibly a rear anti‑roll bar upgrade (e.g., the Whiteline 22mm bar) can restore geometry and complement the KW coilovers. Many owners also replace the rear trailing arm bushings with polyurethane versions to limit deflection under cornering loads. These modifications are not required for daily driving, but they unlock more of the coilovers’ potential on track.

Conclusion

Upgrading your Veloster N with KW coilovers is one of the most impactful modifications you can make for outright driving enjoyment and performance. The costs—ranging from about $2,000 to $3,500 with installation and alignment—are a significant investment, but the measurable improvements in cornering grip, body control, and adjustability transform the car’s character. The detailed installation process rewards careful work, and the resulting setup can be tailored from a comfortable daily driver to a track‑focused weapon with a few clicks of a knob. For any owner who feels the factory suspension is holding the Veloster N back, KW coilovers deliver a precisely calibrated upgrade that respects the car’s hot‑hatch soul while pushing its limits further.
