Dežru Suspension Spec-S for Porsche Boxster. Cayman 987 SPECS-987

The Dežru Spec-S Coilover System for the Porsche Boxster and Cayman 987 is designed to improve handling precision, chassis stability, and driving confidence while preserving the comfort and refinement expected from a road-driven Porsche. Engineered around the 987 platform’s mid-engine layout, suspension geometry, and weight distribution, the Spec-S provides enhanced body control and a more connected driving experience for daily driving, spirited back-road runs, mountain roads, canyon driving, and occasional High-Performance Driver Education (HPDE) events.

Featuring digressive monotube dampers, the Spec-S delivers strong low-speed damping support during braking, cornering, steering inputs, and rapid transitions. This helps reduce excessive body movement and improve steering response while allowing the suspension to absorb uneven pavement and maintain predictable tire contact.

The system features 300 lb/in front and 400 lb/in rear linear HyperCoil springs, selected for a balanced street-performance setup suited to the Porsche 987 Boxster and Cayman. This spring combination is designed to improve front-end precision, provide additional rear suspension support, and maintain compliance over real-world road surfaces without relying on excessive spring stiffness.

The Spec-S incorporates fixed-length damper bodies with an adjustable lowered ride height of approximately 25–40 mm. This allows drivers to achieve a sportier stance while helping preserve usable suspension travel and predictable handling characteristics. OEM-style upper mounts help maintain everyday drivability 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, the Spec-S allows drivers to tailor suspension response to their preferred balance of comfort, control, and performance.

Key Features

• Vehicle-specific application: Designed for the Porsche Boxster and Cayman 987 platform.

• Digressive monotube dampers: Provide responsive chassis support, improved body control, and consistent damping performance.

• Adjustable damping: Allows suspension response to be fine-tuned for everyday driving, spirited road use, and occasional track events.

• Linear HyperCoil springs: 300 lb/in front and 400 lb/in rear spring rates for balanced street-performance handling.

• Adjustable ride height: Approximately 25–40 mm of lowering for a sportier stance.

• Fixed-length damper bodies: Designed to help maintain usable suspension travel throughout the adjustment range.

• OEM-style upper mounts: Help preserve road comfort and reduce unwanted NVH.

• Hand-built, dyno-matched dampers: Promote consistent damping characteristics across both sides of the vehicle.

• Street-focused performance: Suitable for daily driving, mountain roads, canyon driving, and occasional HPDE use.

Performance Benefits

The Dežru Spec-S Coilovers help the Porsche 987 Boxster and Cayman feel more composed and responsive by reducing excessive body roll, pitch, and unwanted suspension movement. The digressive damping profile provides support during initial steering inputs and weight transfers while retaining the compliance needed to handle uneven road surfaces.

The 300 lb/in front and 400 lb/in rear spring combination is intended to balance front-end response with rear suspension support. The front springs help improve braking stability and turn-in, while the rear springs provide additional control during acceleration and cornering.

Combined with adjustable damping and ride height, the Spec-S offers a more controlled, planted driving experience without sacrificing the everyday usability that makes the 987 such an enjoyable sports car.
