Premium suspension for the everyday Impreza.
Designed to lower your Impreza by approximately 25–50 mm, the Spec-S combines premium inverted monotube dampers front and rear with digressive valving for exceptional ride quality, sharper handling, and confidence on every road.
Dežru Spec-S Coilovers – Subaru Impreza (2002–2007 Non-WRX/STI)
The Dežru Spec-S is engineered specifically for the naturally aspirated 2002–2007 Subaru Impreza, combining premium inverted dampers with carefully selected spring rates to deliver exceptional ride quality, improved handling, and a more refined driving experience. Designed around the lighter GD/GG chassis, the Spec-S delivers significantly greater control without compromising everyday comfort.
Unlike many aftermarket coilovers developed around the heavier WRX or STI, the Spec-S is tuned specifically for naturally aspirated Impreza models. Its inverted monotube dampers front and rear dramatically increase suspension rigidity, reducing strut flex during aggressive cornering and braking while improving steering precision. The inverted architecture also reduces unsprung weight by placing the heavier damper body on the chassis, allowing the suspension to react more effectively over broken pavement.
Built for drivers who enjoy daily commuting, spirited back-road driving, mountain roads, and occasional autocross, the Spec-S features digressive piston valving that provides excellent low-speed support during braking, turn-in, and rapid transitions while remaining remarkably compliant over rough pavement and expansion joints. Rather than relying on excessive spring stiffness, the suspension achieves its performance through sophisticated damping that keeps the chassis composed without sacrificing comfort.
Fixed-length damper bodies paired with a 25–50 mm adjustable lowered ride height preserve proper suspension travel and geometry, maintaining predictable handling and excellent ride quality throughout the adjustment range.
Key Features
- Inverted monotube dampers front and rear for increased chassis rigidity, reduced flex, and improved steering response.
- Digressive piston valving for exceptional body control with outstanding ride comfort.
- Fixed-length damper bodies with 25–50 mm adjustable lowered ride height to preserve suspension geometry and usable travel.
- 20-click rebound adjustment for fine tuning ride quality and handling characteristics.
- 275 lb/in front and 275 lb/in rear spring rates, optimized specifically for naturally aspirated Impreza models.
- Linear HyperCoil springs for predictable handling and consistent performance throughout suspension travel.
- OEM-style upper mounts to minimize NVH while maintaining factory fitment.
- Hand-built, dyno-matched damper pairs to ensure precise left-to-right damping consistency.
Performance Character
The Spec-S gives the naturally aspirated Impreza a level of refinement typically found in far more expensive suspension systems. Steering becomes more immediate, body roll is significantly reduced, and the chassis feels substantially more stable without becoming harsh over imperfect roads.
The inverted dampers provide outstanding steering precision while the digressive valving keeps the tires planted over uneven pavement, allowing the suspension to absorb bumps instead of skipping across them. The result is greater driver confidence whether commuting to work or exploring your favorite back roads.
Compared to typical entry-level coilovers, the Spec-S delivers noticeably better body control while maintaining a supple, composed ride that remains enjoyable during long highway drives and daily use.
Why We Recommend 275 lb/in Front & 275 lb/in Rear for the 2002–2007 Subaru Impreza
The naturally aspirated GD/GG Impreza is lighter than its WRX counterpart and doesn't require aggressive spring rates to deliver responsive handling. In fact, many suspension kits developed around WRX spring rates leave the non-turbo chassis unnecessarily stiff.
Our 275 lb/in front and 275 lb/in rear spring package was developed specifically for the naturally aspirated platform, improving chassis response while preserving the smooth, predictable ride expected from a daily driver.
The balanced spring rates allow the digressive dampers to control body movement instead of relying on excessive spring stiffness. This results in a suspension that feels composed and responsive while maintaining excellent mechanical grip and ride quality.
This setup:
- Reduces body roll and brake dive
- Improves steering precision and cornering confidence
- Maintains excellent ride quality on rough pavement
- Preserves predictable AWD balance
- Delivers outstanding comfort for daily driving
Combined with fully inverted dampers and premium digressive valving, the result is a naturally aspirated Impreza that feels sharper, more refined, and considerably more confidence inspiring without sacrificing the comfort that makes it enjoyable every day.
