Description
The Dežru Spec-RS Coilover System is engineered for the first-generation Audi R8, delivering a performance-focused suspension upgrade designed to enhance chassis control, steering response, and stability under demanding driving conditions. Developed for enthusiasts who want to get more from their R8 on spirited road drives and HPDE track days, the Spec-RS combines aggressive damping characteristics with carefully selected spring rates for a more controlled and connected driving experience.
Featuring digressive monotube dampers, the Spec-RS is designed to provide strong chassis support during braking, cornering, and rapid directional transitions while maintaining compliance over uneven pavement. Its performance-oriented damping profile aims to deliver predictable responses to driver inputs and changing loads, helping the vehicle remain composed during demanding driving.
The system incorporates external rear reservoirs, designed to increase fluid capacity and support thermal management during sustained high-load operation. This configuration is particularly relevant for drivers who regularly participate in extended track sessions or spirited driving where damper temperatures can rise.
With fixed-length damper bodies and an adjustable lowered ride height of approximately 30–45 mm, the Spec-RS is designed to provide a lower stance and a more performance-focused suspension setup. Its 450 lb/in front and 625 lb/in rear spring rates, linear HyperCoil springs, and pillowball front top mounts contribute to a firm, responsive suspension package intended for fast-road and track-oriented driving.
Each damper is hand-built and dyno-matched to support consistent damping characteristics across matched components. The result is a suspension system designed for drivers who prioritize precision, chassis control, and feedback from their Audi R8.

Performance Character
The Dežru Spec-RS is designed to give the Audi R8 a more controlled and responsive suspension character during demanding driving. Its digressive damping profile aims to support the chassis during braking, turn-in, and cornering transitions while helping the suspension respond predictably to changing road surfaces and loads.
The 450 lb/in front and 625 lb/in rear spring combination creates a firm, performance-oriented setup intended to provide substantial suspension support. Combined with adjustable damping and external rear reservoirs, the system is designed for drivers who regularly push their R8 beyond ordinary street-driving conditions.
The result is a suspension package focused on steering response, chassis composure, and driver feedback for spirited road driving and occasional or regular HPDE use. Actual performance will depend on tire selection, alignment, damping settings, vehicle configuration, and track conditions.
Why Choose 450 lb/in Front and 625 lb/in Rear Springs?
The Audi R8's mid-engine layout and performance-oriented chassis place particular demands on suspension balance. The Dežru Spec-RS combines 450 lb/in front and 625 lb/in rear springs to provide a firm, performance-focused spring setup intended for demanding street and track use.
Front suspension — 450 lb/in
The front spring rate is designed to provide substantial support during braking and corner entry. It contributes to front-end response and suspension control while working with the damper valving to manage changes in load during aggressive driving.
Rear suspension — 625 lb/in
The rear spring rate provides additional spring support intended to control suspension compression under load. Its effect on acceleration squat, rear traction, and cornering balance depends on the R8's suspension geometry, spring mounting arrangement, drivetrain, and damping settings.
Matched spring and damper performance
Spring rates alone do not determine handling balance. The Spec-RS combines linear HyperCoil springs with digressive monotube damping designed to control body movement and provide consistent suspension response. External rear reservoirs support thermal management during sustained use, while adjustable damping allows the setup to be tailored to different driving conditions.
This configuration is intended for drivers who prioritize suspension support and performance feedback over a soft, comfort-focused ride. Proper alignment and setup are important for achieving predictable handling on both road and track.
Who Is the Dežru Spec-RS For?
The Dežru Spec-RS is intended for Audi R8 owners seeking a more performance-focused suspension setup for:
-
Spirited road and canyon driving
-
HPDE track days and performance driving events
-
Improved chassis support during braking and cornering
-
A lower stance with adjustable damping
-
Drivers who prioritize handling response and suspension control
