Best Suspension Mods for the New Integra Type S: Kw V3 Coilovers and Their $2,500 Performance Boost

The Untapped Potential of the Integra Type S Chassis

Honda’s return to a sporty, three-letter badge with the Integra Type S has thrilled enthusiasts. Underneath its aggressive bodywork lies a chassis that is already remarkably capable straight from the factory. However, the stock suspension, while competent, is a compromise engineered for the mass market. It is tuned to be livable for daily commutes while still providing a hint of track-day spirit. For the dedicated driver, that compromise is the single biggest limitation. The control arms, subframe, and rigid chassis structure are begging for a more focused suspension setup. Unlocking that potential demands a deliberate upgrade, and the KW V3 Coilover system is one of the most proven paths to a transformation that feels like a $2,500 performance boost – because it delivers exactly that.

Why the Factory Suspension Holds You Back

Before diving into the aftermarket, it helps to understand exactly what the OE suspension does – and doesn’t – do. The Integra Type S arrives with adaptive dampers (the ADS system) that automatically adjust to driving conditions and selected drive modes. In its most aggressive “Sport+” setting, the dampers firm up noticeably, reducing body roll and providing sharper transient response. But even then, the system is fundamentally limited by its fixed spring rates and minimal travel. The car still rolls more than a serious performance driver wants, and the dampers can struggle to control secondary oscillations after a sharp bump mid-corner. The adaptive system is a black box – you cannot fine-tune rebound vs. compression independently, and the ride height is not adjustable. You get what Honda engineers deemed acceptable, which is excellent for a production car but far from optimal for any sort of purposeful driving. A fixed-rate performance coilover like the KW V3 sidesteps those constraints entirely, giving the driver total authority over the suspension’s behavior.

The Compromise of Adaptive Dampers

Adaptive dampers (sometimes misnamed “active suspension”) are electro-hydraulic valves that change oil flow within the damper body. In the Integra Type S, the ADS varies damping force within milliseconds. The upside is compliance on rough roads and firmness when you push hard. The downside is that the system is reactive, not predictive. It cannot anticipate a corner or a dip. Moreover, the range of adjustment is narrow compared to a quality manually adjustable coilover. The dampers also add weight and complexity, and replacement cost is high. For anyone planning to track the car or simply wanting more precision, the ADS becomes an expensive handicap. KW V3 coilovers replace the entire strut assembly with a high-performance monotube design, eliminating the adaptive valve entirely in favor of precise, independently adjustable compression and rebound circuits.

Deep Dive: The KW V3 Coilover System for the Integra Type S

KW Automotive has been building suspension systems for over two decades, and their V3 series sits at a sweet spot between street usability and serious track capability. The V3 is not a full-race coilover; it retains rubber top mounts for noise isolation and uses a stainless steel body and Inox-Line technology for corrosion resistance, making it suitable for year-round use. What sets it apart is the independent adjustment of rebound damping (16 clicks) and low-speed compression damping (12 clicks). This is a crucial feature: low-speed compression controls how the car reacts to driver inputs (braking, throttle, steering), while rebound controls how quickly the suspension unloads after a bump or after cornering. Being able to tune these independently allows a driver to dial out understeer, control pitch, and maximize rear grip without sacrificing ride quality on the highway.

Key Technical Specifications

• Adjustable Ride Height: The V3 allows lowering of 20–50 mm (approx. 0.8–2.0 inches) while maintaining factory suspension travel. This is critical – many budget coilovers reduce bump travel, leading to harsh bottoming. KW’s design retains near-OE suspension travel for everyday usability.
• Independent Damping Adjustment: 16 clicks of rebound and 12 clicks of low-speed compression. High-speed compression is fixed and calibrated by KW for safe, predictable behavior over sharp impacts.
• Stainless Steel Body: Resists corrosion from road salt and moisture. The Inox-Line finish is a visual plus and a functional necessity for longevity in winter climates.
• Dual Flow Valve (DFV) Technology: KW’s patented valve design ensures that the damper responds instantly to changes in piston speed, providing consistent damping force regardless of temperature or age. This is a major upgrade over OEM twin-tube designs.
• Noise-Free Top Mounts: Unlike many track-oriented coilovers, the V3 uses rubber top mounts that prevent clunking and vibration transfer to the cabin. The result is a ride that is quieter and more refined than many competitors that use solid pillow-ball mounts.

Real-World Performance Gains: More Than Lap Times

While a $2,500 suspension upgrade might seem steep, the performance dividends extend far beyond a stopwatch. The Integra Type S, with its limited-slip differential and potent 320 hp K20C engine, often feels like it is fighting its own body roll in tighter sections. The KW V3 addresses this directly. On a typical autocross course or road track, cars equipped with a properly tuned V3 setup have reported consistent gains of 1–2 seconds per lap on a 60-second circuit. That is a meaningful improvement that cannot be achieved with tires or engine tuning alone. But the benefits measure beyond raw lap time: the driver feels a new level of connection. The car rotates willingly with throttle input, the front end bites harder under braking, and mid-corner bumps no longer upset the chassis. The $2,500 sticker buys confidence, consistency, and a far more engaging driving character.

Measurable Improvements

• Reduced Lateral Body Roll: Stock roll rates are moderate, with the car leaning noticeably in hard corners. The KW V3 reduces roll by approximately 30–40%, keeping the tires flatter on the pavement and improving contact patch usage.
• Improved Brake Dive: The lower ride height and stiffer spring rates (typically around 450–500 lb/in front, 600–700 lb/in rear, depending on configuration) dramatically reduce nose dive under hard braking. This maintains the car’s geometry and allows later braking points with greater stability.
• Better Traction on Uneven Surfaces: The DFV valving allows the wheel to follow the road surface without losing contact, even at moderate damper settings. This means fewer traction control interventions and more power down exiting corners.
• Enhanced Steering Feel: By reducing compliance in the suspension, more of the steering input is transmitted directly to the road. The driver feels a sharper initial turn-in and better communication of front tire slip angle.

Installation: What to Expect and Tools Required

Installing coilovers on a modern Honda platform is a well-documented process, but the Integra Type S has a few quirks. The job is achievable by an experienced DIYer with proper tools, but it is not a beginner project. Expect 5–8 hours for a first-time fitment, including cleanup, torque settings, and initial setup. Professional installation typically runs $400–$600 and is recommended if you lack experience with spring compressors or chassis alignment.

Basic Installation Steps

1. Preparation: Jack the car, secure on jack stands (four stands for level work), remove wheels. Spray all fasteners with penetrating oil (e.g., PB Blaster) 24 hours prior.
2. Front Strut Removal: Detach the sway bar end link, ABS cable bracket, and brake line bracket from the strut body. Remove the three upper strut mount bolts under the hood. Compress the stock spring (extremely dangerous without a proper spring compressor – do not attempt with zip ties or floor jacks). Then unbolt the lower fork from the knuckle. Lift the entire strut assembly out.
3. Rear Strut Removal: Remove the rear seat bottom and side bolsters to access the upper mount. Unbolt the lower shock bolt from the knuckle. Carefully lower the assembly. The rear spring sits separately – you may need to disconnect the sway bar link to lower the control arm enough to remove the spring.
4. Coilover Assembly: Transfer any stock components (dust boots, bump stops) to the new KW V3 units per the included instructions. Do not reuse OEM top mounts – KW supplies their own for the rear (the front uses a modified factory top mount). Torque all nuts to spec with a torque wrench.
5. Installation: Reverse the removal process. Pay close attention to the orientation of the coilover – the lower fork must be aligned with the steering arm. Use a pry bar if needed to align the lower bolt holes. Torque all suspension bolts with the car at normal ride height (wheels on or on ramps) to prevent binding of bushings.
6. Initial Damping Setup: KW recommends starting with rebound and compression set to 12 clicks out from full stiff (i.e., most of the adjustment range). You will fine-tune later.
7. Alignment: Before driving, get a professional alignment. The KW V3 lowers the car – expect changes in camber and toe. Typical street settings: -1.5 to -2.0 degrees front camber, -1.5 degrees rear, 0 total toe, or slight toe-in for stability. The car will pull or wander if alignment is off.

Damping Tuning Guide: Dialing in the KW V3

The beauty of the V3 is the ability to tune the suspension to your taste and driving environment. Here is a practical starting point and adjustment guide:

Initial Settings for Street and Track

• Street Comfort: Rebound 16 clicks (full soft), Compression 10 clicks (full soft). This prioritizes compliance over control. Suitable for rough roads and daily driving, though you will still feel more than stock.
• Sport Street: Rebound 12 clicks, Compression 6 clicks. A balanced setting that is firm but compliant. Good for spirited back-road driving and occasional autocross.
• Track Day: Rebound 8 clicks, Compression 4 clicks. Firm enough to control body roll aggressively, but still absorb bumps. This is a common starting point for a road course.
• Competition: Rebound 4 clicks, Compression 2 clicks. Very firm. Only use on smooth racetracks. Can be harsh on street and may cause skip over rough patches.

Fine-Tuning Tips

When adjusting damping, always start from full stiff (0 clicks) and count clicks outward. Never force a knob past its stop – you can damage the valve. Make changes in 2-click increments, then drive a familiar loop. If the car understeers on corner entry, reduce front rebound by 2 clicks (softer) or increase front compression by 2 clicks (firmer). If the car feels bouncy after a bump, soften rebound on that axle. If the car dives under braking, increase front compression. When you find a setting that works for a specific track, log the clicks. The KW V3 allows repeatable, consistent setups.

Cost vs. Value Analysis: The $2,500 Performance Boost

The price of a KW V3 kit for the Integra Type S typically sits around $2,500–$2,800, depending on vendor and any sales. Is it worth the money? Compare it to other common performance upgrades:

Upgrade	Approximate Cost	Performance Gain (lap time)	Overall Driving Impact
KW V3 Coilovers	$2,500	1–2 seconds	Transforms handling, adjustability, ride quality
Performance tires (set of 4)	$1,000–$1,500	0.5–1 second	Improves grip, but no change to roll/dive
Engine tune (stage 1)	$600–$800	0.3–0.5 second	More power, but chassis remains soft
Lightweight wheels + tires	$3,000+	0.4–0.8 second	Better unsprung mass, but marginal suspension improvement
Full exhaust system	$1,500–$2,500	0.1–0.2 second	Sound and minor power, no handling gain

As the table shows, the KW V3 offers the largest single improvement in lap time and driving dynamics for its price point. It also provides adjustability that no other component can match. When you consider that a moderate investment in coilovers transforms the car from a sporty daily driver to a genuine track tool, the $2,500 seems less like an expense and more like unlocking the car’s true nature.

Maintenance and Longevity of KW V3 Coilovers

Proper maintenance ensures your $2,500 investment lasts. KW uses stainless steel bodies and sealed cartridges, but the adjusters can collect dirt. Here are key care tips:

• Regular Cleaning: After winter or heavy dirt exposure, rinse the damper bodies and adjuster knobs with a gentle spray of water. Do not use pressure washers directly on the seals.
• Check for Leaks: Inspect the damper shaft for oil film every oil change. A slight trace is normal; any pooling or dripping indicates a seal failure. KW offers rebuild services for a fee.
• Lubricate Adjusters: Every 6 months, apply a small amount of silicone grease to the rebound and compression adjuster knobs to keep them turning smoothly and prevent corrosion.
• Corrosion Protection: If you drive in salt, consider applying a light spray of corrosion inhibitor (e.g., Boeshield T-9) on the lower mounts and spring perches. Do not spray on the damper rod.
• Annual Inspection: Have a suspension shop check for play in the top mounts, control arm bushings, and ball joints. Good coilovers will outlast the car if maintained.

Alternative Suspension Mods to Consider

While the KW V3 is a standout, it is not the only option. Depending on your budget and goals, you might also look at these alternatives:

KW V1 and V2 Coilovers

KW also offers V1 (fixed damping, height-adjustable) and V2 (rebound-adjustable only). These are $200–$400 cheaper but lack the independent compression adjustment that makes the V3 so flexible. For a daily driver who rarely tracks, the V2 can be a good compromise. But if you intend to push the car, the V3 is worth the premium.

Öhlins Road & Track Coilovers

Öhlins offers a coilover kit for the new Integra Type S that is even more premium, with DFV technology and a reputation for supple ride quality. However, the price exceeds $3,500. The KW V3 is a more accessible option that still delivers outstanding performance.

Sway Bar Upgrades

A less expensive path is upgrading the front and rear anti-roll bars. A thicker rear bar (e.g., 22–25 mm) can reduce understeer for under $500. However, sway bars do not fix poor damping control or ride height. They work best in conjunction with quality coilovers.

Spring and Damper Separates

You can purchase performance dampers (like Koni Yellow) and match them with lowering springs (e.g., Eibach or Swift). This approach is cheaper (around $1,500) but lacks the ride-height adjustability and integrated design of a true coilover. For the Integra Type S, the damping characteristics of a matched coilover system are superior to a spring/damper combo.

Real Driver Experiences: Before and After

To give context to the numbers, here is a typical owner report from an Integra Type S forum (anonymized):

“I installed the KW V3s over a weekend with a friend. The car dropped about 1.2 inches. First drive, I was shocked at how controlled it felt. The factory car would pitch and roll through a freeway on-ramp; now it just goes flat. I started at KW’s recommended settings and after a few adjustments, I found 12 rebound and 6 compression perfect for the smooth back roads near me. The steering feels alive. I ran a track day at Buttonwillow and dropped 2.1 seconds from my previous best with just an alignment and the stock tires. The car never understeered on exit like before. The only downside is the ride is firmer – my wife noticed – but I don't mind. This is how the Type S should have come from the factory.”

This sentiment is echoed across many owners. The KW V3 does not ruin the car’s comfort; it refines it. The damping is tuned to be compliant over small bumps while controlling large movements. The result is a car that feels both more luxurious and more capable.

Final Verdict: Is the $2,500 Investment Worth It?

If you are an Integra Type S owner who is serious about performance driving – autocross, track days, or simply carving your favorite canyon roads – the KW V3 coilovers are arguably the single best modification you can make. The factory suspension is a reasonable starting point, but it leaves a significant amount of performance on the table. With the KW V3, you gain:

• Independent compression and rebound adjustment for precise tuning.
• Lowered center of gravity and reduced weight transfer.
• Durability that withstands track abuse without degrading.
• No electronic trickery – just pure mechanical connection.

The $2,500 price tag may seem intimidating, but when you consider that a set of high-end tires costs half that and only offers incremental gains, the coilovers represent far better value. They transform the character of the Integra Type S, turning a great car into a truly special one. For anyone who feels that the stock car is just a few chassis tweaks away from greatness, the KW V3 is the shortcut to that promise.
