C5/C6 Corvette - FPSpec "Long Stroke" Ohlins DFV Coilover Kit (Steel Chassis Only)

Featured on TJHUNT's Dream Corvette Build

Fitment – C5 / C6 Steel Frame

This FPSpec x Kraken Performance Öhlins DFV kit is designed specifically for:

• C5 Corvette – All steel frame models
• C6 Base & C6 Grand Sport – Steel frame chassis

Important: This steel-frame kit does require modification to the front upper shock mounts.

This kit does not fit: C6 Z06 or C6 ZR1 Aluminum frame cars.

For the C6 Z06 & ZR1 - refer to our C6 Z06/ZR1 Remote-Canister Öhlins kit. The remote-canister kit is reverse-compatible with steel chassis cars and requires no modification to the front upper mounts, but is a more expensive alternative compared to this product.

Kraken Performance FPSpec "Long-Stroke" Öhlins DFV Coilovers

The Gold Standard for C5/C6 Corvette Coilovers

We are proud to introduce the Kraken Performance FPSpec Long-Stroke Öhlins DFV coilover system—the ultimate suspension solution for the C5/C6/C7/C8 Corvette owner who actually uses the car: street, backroads, autocross, HPDE, or all of the above.

From Koenigsegg to Pagani, Öhlins dampers are known for their support at the limit and uncanny ride quality—exactly what you want in a car that has to pull double duty.

The result is a long-stroke, Corvette-specific coilover that delivers:

• Track-ready body control and stability
• Real-world ride quality on imperfect roads
• A wide, usable range of damping adjustment so you can genuinely tune the car for your use case

Spring Packages – Tuned for Real Corvette Use

We don’t expect you to dig through forums and guess spring rates. FPSpec offers pre-curated spring packages that cover the majority of C5/C6 applications, plus custom options for more radical builds.

FPSpec Grand Touring

For the backroad and street-focused Corvette that still sees spirited driving.

• Best balance of ride quality vs. body control
• Soaks up expansion joints and rough pavement without feeling floaty
• Extremely capable for the occasional autocross or HPDE

FPSpec Performance Street / Track

For owners who split their time between aggressive street driving and regular track days.

• Higher rates and valving emphasis on precision and mid-corner support
• Ideal for high-grip tires and performance alignment settings
• The sweet spot for a “one car does everything” build

FPSpec Track Dedicated

For the frequently tracked Corvette where performance takes priority over comfort.

• Significantly higher rates for maximum body control and stability under braking and high-speed transitions
• Designed around track compounds and aero/track-focused setups
• Best for cars that live at the circuit and tolerate a firmer ride on the street

FPSpec Tailored

For specialized builds—widebodies, aero cars, big-power track cars, or unusual use cases.

• Bespoke consultation on spring rates, anti-roll bars, and valving targets
• Optional helper spring configurations (additional charges apply where required)
• Ideal for owners who want a suspension package engineered around their exact spec

Öhlins Dual Flow Valve (DFV) – Why It Matters

Designing a damper for only street comfort or only track performance is easy. Building one that truly works in both environments is where DFV earns its reputation.

Öhlins’ patented Dual Flow Valve (DFV) architecture, combined with precision internal machining, low-friction seals, and Öhlins 1304 shock oil, yields an ultra-low hysteresis damper that can respond to bumps measured in fractions of a millimeter.

What that means in the car:

• Maximum mechanical grip in long sweepers and combined braking/cornering
• The ability to take curbs and surface transitions without upsetting the chassis
• A firm-but-supple ride on real-world roads

Corvette owners who’ve driven this setup consistently report:

• More comfort than stock over broken pavement
• Far higher confidence and grip when driven hard

In short: it feels like two suspensions in one—composed and fast on track, yet genuinely livable on the street.

The Öhlins DFV architecture has become the go-to “road & track” solution in this segment for a reason—there is nothing else near this price point that offers the same combination of grip, feedback, and refinement.
