Note

The H. Drive Euro Spec coilovers are expertly crafted for European vehicles, offering a refined balance of comfort and dynamic performance. Designed to handle the unique demands of European road conditions, they excel in providing precise handling for both daily drive and track use. The Euro Spec delivers exceptional control and ride quality tailored to your needs.

• Supplied Spring Rates may differ from advertised
• Please note that not all vehicles use camber plates in the front and/or rear. Some vehicles reuse OEM upper mounts.
• The vehicle ride height can be lowered 25mm to 95mm
• The H. Drive coilovers feature a high performance monotube damping system. Due to its enlarged valve and integration of gas and oil within a single chamber, a slight noise may occur when driving slowly over rough terrain, indicating normal damper operation.

Damping Adjustability

Euro Spec offers individually adjustable rebound stage damping for optimal driving performance and comfort. With 30 levels of adjustability, drivers can fine tune both front and rear compression damping to suit their preferred driving style and road conditions. This advanced system allows for a smoother, more responsive connection on fast roads and improved vehicle control. On rough surfaces, customized rebound damping can significantly enhance driving comfort, ranging from softer settings (lower damping force) to firmer settings (higher damping force) for a more precise and tailored driving experience.

Ride Height Adjustability

Euro Spec coilovers feature an advanced ride height adjustment system, controlled by the position of the coilover’s bottom mount, which can be easily moved up or down along the damper body. This innovative design provides a broad range of height adjustments without affecting the spring’s preload, enabling precise tuning without sacrificing performance. With the ride height set by the adjustable bottom mount rather than the spring platform, Euro Spec coilovers retain full damper travel at any selected height. This ensures optimal damper travel for a smoother, more controlled ride, making these coilovers perfect for both street and track applications.

Camber Adjustability

For Euro Spec coilovers, models that support camber adjustment come with camber adjustable aluminum pillowball top mounts as standard. These mounts are high quality that enables precise adjustments, allowing you to fine tune the camber angle for street or track applications. This flexibility offers enhanced control and handling, helping you achieve the exact alignment specifications needed for various driving styles and conditions.

Large 52mm Piston

Designed with a 52mm piston in certain models, the Euro Spec coilovers maximize shock absorption through increased fluid capacity. The larger piston surface area enhances the coilover damping efficiency, improving handling under high loads and during intense driving scenarios. This design minimizes heat buildup, helping to prevent performance fade over time. The result is consistent, stable control and a smooth transition from street driving to track conditions.

Forged Aluminum Upper Mounts & Sheets

Select models of H. Drive Euro Spec coilovers are equipped with forged aluminum upper mounts, engineered to reduce weight while enhancing suspension responsiveness. The aluminum construction improves overall handling and cornering performance, ensuring precise, reliable control in demanding driving conditions. This high grade forged aluminum is designed to resist environmental wear, enhancing both durability and lifespan. The forged aluminum components provide a lightweight yet robust structure with excellent heat dissipation, corrosion resistance, and adaptability for suspension customization. This advanced construction yields a superior strength to weight ratio, critical for achieving optimal balance and control without sacrificing durability.

Corrosion Resistance

Euro Spec coilovers are built to withstand all environments, while key steel components undergo a powder coating process. The black anodized coating on the coilovers provides exceptional corrosion resistance, crucial for durability in varied weather conditions. This advanced coating shields the aluminum components from moisture and road salt, extending their lifespan. This advanced protection ensures that the coilovers retain their premium look and peak performance, even through harsh winters and tough environments.

Coil Springs

Each Euro Spec coilover is built from top grade materials, the high strength spring is made of SAE9254 chrome silicon steel. Each vehicle is specifically adjusted in the respective suspension damper in its spring rate for long life; it is multi coated. These springs are tested for over 500,000 cycles with less than 5% deformation

Premium Quality Oil

The Euro Spec coilovers utilize specially formulated damper oil, optimized for consistent performance across various temperatures. This oil maintains its viscosity under high stress conditions, ensuring stable damping force and reliability in both daily use and high-demand track scenarios. The premium oil’s resistance to thermal breakdown contributes to extended damper life and dependable performance over time.

Nitrogen Pressurized Dampers

Euro Spec coilovers are nitrogen pressurized, minimizing oil aeration to maintain steady damping force during rapid damper movements. This pressurization prevents bubble formation, ensuring consistent damping and improved stability, especially under aggressive driving conditions. This feature supports durability and performance consistency for both street and motorsport applications.

Spring Rate

At H. Drive Motorsport, we understand the importance of spring rates in delivering the perfect balance of comfort and performance. Our Euro Spec coilovers are carefully tested and calibrated to provide optimal spring rates for both road and track use, ensuring that every drive is smooth yet responsive. Whether you’re commuting on the street or pushing the limits on the track, our springs are designed to handle it all. However, we also recognize that every enthusiast’s needs are unique. For those seeking a more aggressive setup, we offer the option to customize the spring rate, allowing you to tailor your suspension to your specific driving style and performance goals.
