Description
The Dežru Spec-S Coilover Suspension System for the Subaru BRZ is engineered to enhance chassis control, sharpen handling response, and preserve the balanced, driver-focused character of this lightweight, rear-wheel-drive sports coupe. Designed for enthusiasts who want a more responsive suspension setup without sacrificing everyday usability, the Spec-S is suited to daily driving, spirited street driving, canyon roads, autocross, and occasional high-performance driving events (HPDE).
Featuring digressive inverted monotube dampers, the Spec-S is designed to provide effective low-speed damping for improved control during braking, turn-in, cornering, and directional transitions. Its damping characteristics aim to manage body movement while maintaining compliance over uneven pavement, helping the BRZ feel more composed and predictable in a variety of driving conditions.
The system combines 450 lb/in front springs and 500 lb/in rear springs with linear HyperCoil springs and adjustable damping. This configuration is intended to balance front-end support with rear suspension response, supporting a more engaging driving experience while allowing the driver to fine-tune damping according to road conditions and personal preferences.
The Spec-S features fixed-length inverted damper bodies and an adjustable ride-height range of approximately 25–50 mm (1–2 inches) lower than standard ride height. This design is intended to preserve appropriate damper operation and usable suspension travel when the system is correctly installed and adjusted. OEM-style upper mounts maintain a factory-style mounting arrangement, while hand-built, dyno-matched damper pairs are designed to provide consistent damping performance from side to side.
With a target ride-frequency range of approximately 2.0–2.3 Hz, the Dežru Spec-S is designed for drivers seeking a performance-oriented suspension setup that balances chassis response, driver feedback, and street usability.

Performance Character
Improved Chassis Control
The Dežru Spec-S is designed to reduce excessive body movement and improve chassis composure during cornering, braking, and rapid directional changes. The digressive damping profile aims to provide responsive control during initial suspension inputs while maintaining compliance over common road imperfections.
Responsive Turn-In and Directional Transitions
The combination of spring rates and damping characteristics is intended to support more controlled turn-in and predictable transitions. The resulting steering response and front-end grip will also depend on tire selection, alignment, ride height, and the vehicle's overall suspension configuration.
Balanced Front-to-Rear Response
The 450 lb/in front and 500 lb/in rear spring rates form part of a setup intended to balance front-end support with rear suspension response. When properly configured, the system aims to provide a more controlled and engaging driving feel while preserving the BRZ's lightweight, rear-wheel-drive character.
Adjustable Damping for Street and Track Use
Adjustable damping allows drivers to fine-tune suspension response for different driving environments. Settings can be selected to suit everyday road use or more demanding autocross and HPDE conditions, within the adjustment range supported by the kit.
Lowered Ride Height
The approximately 25–50 mm lowering range provides flexibility when setting vehicle stance and suspension behavior. Correct ride-height adjustment is important for maintaining suitable suspension travel, alignment, tire clearance, and damper operation.
Why Choose 450 lb/in Front and 500 lb/in Rear?
The Dežru Spec-S uses 450 lb/in front springs and 500 lb/in rear springs as part of a performance-focused suspension configuration for the Subaru BRZ.
The front spring rate is intended to provide support during braking and steering inputs, while the rear spring rate contributes to the vehicle's overall response during cornering and transitions. The digressive damper valving works alongside the springs to manage suspension movement, rather than relying on spring stiffness alone.
This combination is designed to support:
-
More controlled body movement during cornering
-
Responsive behavior during turn-in and directional transitions
-
A balanced front-to-rear suspension response
-
Adjustable damping for different road and driving conditions
-
A performance-oriented setup that remains suitable for street use when correctly configured
Spring rates alone do not determine whether a vehicle will understeer, oversteer, or maintain a particular level of grip. Those characteristics also depend on suspension geometry, motion ratios, anti-roll bars, alignment, tires, damper settings, and driving conditions. The 450/500 lb/in configuration should therefore be understood as the specified spring setup for this kit, rather than a universal solution for every BRZ driving style.
Who Is It For?
The Dežru Spec-S Coilovers are intended for Subaru BRZ owners who want adjustable suspension response and improved chassis control for both street and occasional performance driving. They may suit drivers who use their car daily but also enjoy spirited back-road driving, autocross, or HPDE events.
For track use, professional installation and alignment are recommended. Ride height and damping should be configured to suit the tires, driving conditions, and intended use.
Product Summary
The Dežru Spec-S Coilovers for the Subaru BRZ combine digressive inverted monotube dampers, adjustable damping, fixed-length damper bodies, linear HyperCoil springs, and OEM-style upper mounts. With 450 lb/in front and 500 lb/in rear spring rates and an adjustable lowering range of approximately 25–50 mm, this suspension system is designed to deliver more controlled body movement, responsive handling, and versatile street-oriented performance.
