Description
Enhance your Ferrari 458's suspension performance with the Dežru Spec-S Coilover System, engineered for drivers seeking precise chassis control, improved cornering stability, and adjustable ride height while preserving the Ferrari's naturally responsive driving character. Designed around the 458's mid-engine layout, weight distribution, and performance-oriented suspension characteristics, the Spec-S combines digressive damping technology, carefully selected spring rates, and adjustable suspension settings to deliver a more controlled and confidence-inspiring driving experience.
Whether driving on the street, navigating winding canyon roads, or enjoying occasional track days, the Dežru Spec-S coilovers are designed to reduce excessive body movement, improve steering response, and support predictable handling under demanding driving conditions.
Advanced Damping Technology
The Dežru Spec-S features digressive monotube dampers designed to provide strong low-speed damping support during braking, corner entry, steering inputs, and rapid directional transitions. This damping profile helps control body roll and pitch while maintaining compliance over uneven pavement and other road imperfections.
The adjustable damping system allows drivers to fine-tune rebound behavior according to their preferred driving style and road conditions. This flexibility helps balance everyday drivability with the firmer, more controlled suspension response desired during spirited driving and track use.
With a targeted ride frequency of approximately 2.0–2.2 Hz, the Spec-S is designed around a performance-focused tuning philosophy that prioritizes chassis control, driver feedback, and usable road comfort rather than excessive stiffness.
Adjustable Ride Height and Suspension Geometry
The Spec-S coilover system features fixed-length damper bodies with an adjustable lowered ride height of approximately 30–45 mm. This adjustment range provides a lower, more aggressive stance while aiming to preserve usable suspension travel and predictable handling characteristics.
For the Ferrari 458, maintaining an appropriate relationship between ride height, suspension geometry, and available damper travel is particularly important for consistent handling under braking and cornering loads. Correct setup and professional wheel alignment help optimize the suspension's performance while accounting for the vehicle's intended use and tire configuration.
Performance-Tuned Spring Rates
The Dežru Spec-S system uses carefully selected spring rates designed to support the Ferrari 458's mid-engine platform and high-performance driving characteristics.
-
Front Spring Rate: 750 lb/in
-
Rear Spring Rate: 950 lb/in
These spring rates are intended to provide firm suspension support, reduce excessive body roll, and promote predictable weight transfer during acceleration, braking, and cornering. The front-to-rear spring combination is designed to balance steering precision with rear-end stability and traction.
The system incorporates linear HyperCoil springs, which provide a consistent spring rate throughout their working range. Combined with the damper valving, they support predictable suspension response as cornering and braking loads increase.
OEM-Style Upper Mounts and Precision Assembly
The Dežru Spec-S coilovers incorporate OEM-style upper mounts designed to maintain a practical balance between suspension performance and everyday refinement while helping minimize additional noise, vibration, and harshness (NVH).
Each system is hand-built, with dyno-matched damper pairs intended to provide consistent damping characteristics between the left and right sides. This attention to assembly and damping consistency helps promote balanced suspension behavior and predictable driver feedback.
