Dežru Suspension Spec-S for Porsche Boxster 986 SPECS-986

The Dežru Spec-S Coilover System for the Porsche Boxster 986 is engineered to improve handling precision, chassis stability, and driving confidence while preserving the balanced and engaging character of Porsche’s lightweight, mid-engine roadster. Designed around the 986’s suspension geometry and weight distribution, the Spec-S delivers improved body control and steering response for daily driving, spirited back-road runs, canyon driving, and occasional High-Performance Driver Education (HPDE) events.

Featuring digressive monotube dampers, the Spec-S provides responsive low-speed damping support during braking, cornering, steering inputs, and rapid transitions while maintaining compliance over uneven pavement. This approach helps reduce excessive body movement without relying on unnecessarily stiff springs, allowing the tires to maintain contact with the road and supporting predictable handling.

The system features 250 lb/in front and 350 lb/in rear linear HyperCoil springs, selected for a balanced street-performance setup suited to the Porsche 986 Boxster. This spring combination is designed to improve front-end response, provide additional rear suspension support, and maintain everyday ride comfort.

The Spec-S incorporates fixed-length damper bodies with an adjustable lowered ride height of approximately 25–40 mm, helping achieve a sportier stance while aiming to preserve usable suspension travel and predictable handling characteristics. OEM-style upper mounts help maintain road manners and reduce noise, vibration, and harshness (NVH).

Each system features hand-built, dyno-matched damper pairs to promote consistent left-to-right damping performance. With adjustable damping, drivers can fine-tune suspension response to suit their driving preferences and road conditions.

Performance Benefits

The Dežru Spec-S Coilovers help the Porsche 986 Boxster feel more composed and responsive by reducing excessive body roll, pitch, and unwanted suspension movement. The digressive damping profile supports initial steering inputs and weight transfers while allowing the suspension to absorb imperfections in real-world road surfaces.

The 250 lb/in front and 350 lb/in rear spring combination is intended to balance front-end precision with rear suspension control. The front springs support braking stability and turn-in, while the rear springs provide additional support during acceleration and cornering.

Combined with adjustable damping and ride height, the Spec-S offers a sharper, more planted driving experience while retaining the comfort and predictability expected from a road-driven Porsche Boxster.
