Dežru Suspension Spec-RS for Porsche 911 997 Turbo SPECRS-997TURBO

The Dežru Spec-RS Coilover System for the Porsche 911 (997) Turbo is designed for enthusiasts seeking enhanced suspension control, sharper steering response, and motorsport-inspired handling. Developed around the Porsche 997 platform’s rear-engine layout and suspension geometry, the Spec-RS aims to improve chassis stability and driver feedback while retaining the responsive character that defines the 911 driving experience.

Featuring digressive monotube dampers, the Spec-RS delivers strong low-speed damping support during braking, corner entry, steering transitions, and cornering. This design helps control body movement and maintain a composed chassis while allowing the suspension to respond to uneven road surfaces. The result is a more controlled and predictable driving experience for spirited street driving, canyon roads, and track-focused applications.

The system features 300 lb/in front and 500 lb/in rear linear HyperCoil springs, providing a performance-oriented spring combination intended to balance front-end response with rear suspension support. The spring rates work alongside the damper tuning to help manage weight transfer, improve cornering stability, and maintain predictable handling under demanding driving conditions.

The Spec-RS uses fixed-length damper bodies with an adjustable lowered ride height of approximately 30–45 mm, allowing drivers to achieve a lower stance while aiming to preserve usable suspension travel and consistent handling characteristics. Pillowball front top mounts provide a more direct connection between the suspension and chassis, supporting precise steering response and alignment consistency.

Each system features hand-built, dyno-matched damper pairs to promote consistent damping performance from side to side. With adjustable damping, drivers can fine-tune suspension response to suit their preferred setup for street or track use.

Performance Benefits

The Dežru Spec-RS Coilovers are designed to reduce excessive body movement and improve the Porsche 911’s composure during braking, cornering, and acceleration. The digressive damping profile provides responsive support during initial steering inputs and weight transfers while maintaining controlled suspension movement as road and track conditions change.

The 300 lb/in front and 500 lb/in rear spring combination is intended to balance front-end precision with rear suspension support. When matched to the appropriate dampers, this setup aims to improve steering response, cornering stability, and control during corner exit.

The pillowball front top mounts provide a more direct suspension connection, appealing to drivers who prioritize precise feedback and a performance-focused setup. Combined with adjustable damping and ride height, the Spec-RS offers a configurable suspension package for demanding street driving and track use.
