Description
The Dežru Spec-RS coilover system is engineered for the Lamborghini Aventador, delivering enhanced chassis control, precise damping response, and a more connected driving experience. Designed for enthusiasts seeking a performance-focused suspension setup, the Spec-RS combines motorsport-inspired damper technology with adjustable ride height to support spirited street driving, canyon runs, and High-Performance Driver Education (HPDE) events.
Featuring digressive monotube dampers and external rear reservoirs, the Spec-RS is designed to provide consistent damping performance under demanding conditions. The external reservoirs increase oil capacity and heat-management potential, helping maintain more consistent damping characteristics during sustained high-load driving.
The system features fixed-length damper bodies and an adjustable ride height approximately 30–45 mm lower than stock, allowing drivers to customize the Aventador’s stance and handling characteristics. Proper setup and alignment remain essential to preserving suspension travel, tire contact, and predictable vehicle behavior.
Key Features
-
Digressive monotube dampers: Designed to provide responsive chassis control during braking, cornering, and rapid transitions.
-
External rear reservoirs: Support improved thermal management and consistent damping during extended spirited driving and track sessions.
-
Fixed-length damper bodies: Designed to work with the system’s ride-height adjustment range.
-
Adjustable ride height: Allows approximately 30–45 mm of lowering, subject to vehicle configuration and final setup.
-
Adjustable rebound damping: Allows suspension response to be fine-tuned for different driving conditions and driver preferences.
-
400 lb/in front and 525 lb/in rear spring rates: A performance-oriented spring-rate combination designed to work with the Spec-RS damping characteristics.
-
Linear HyperCoil springs: Provide a predictable, consistent spring response through suspension compression.
-
Pillowball front top mounts: Designed to improve steering response and provide more direct suspension feedback.
-
Hand-built, dyno-matched dampers: Each matched pair is tested to help ensure consistent damping performance from side to side.
Performance and Handling
The Dežru Spec-RS suspension system is designed to improve the Aventador’s composure during braking, corner entry, direction changes, and sustained cornering. Its digressive damping characteristics aim to provide strong body-motion control while retaining compliance over smaller road imperfections.
The adjustable rebound damping allows drivers to refine how quickly the suspension returns after compression, helping tailor the vehicle’s response to road conditions, tire selection, and driving style. Combined with the linear HyperCoil springs, the system is intended to deliver a more controlled and predictable feel during aggressive driving.
The external rear reservoirs support damping consistency during extended high-load use, when heat buildup can affect damper performance. Proper setup, suitable alignment, and appropriate damping adjustments remain essential to achieving the desired balance between stability, grip, and ride quality.
Why Choose 400 lb/in Front and 525 lb/in Rear Spring Rates?
The Lamborghini Aventador combines a mid-engine layout, all-wheel drive, substantial power, and a performance-oriented suspension design. Selecting suitable spring rates requires consideration of more than static weight distribution alone. Suspension geometry, motion ratios, damper valving, tire characteristics, vehicle configuration, and intended use all influence the final setup.
The Dežru Spec-RS configuration uses 400 lb/in front and 525 lb/in rear spring rates as part of a performance-focused suspension package.
The front spring rate is intended to provide support during braking and turn-in, helping manage suspension movement and maintain a controlled front-end response. The rear spring rate provides additional support for rear suspension loads during acceleration and cornering transitions.
When correctly matched to the Spec-RS damping characteristics, this combination is designed to improve chassis control, reduce excessive body movement, and provide a more consistent response during spirited driving and HPDE use. Actual handling balance will depend on the vehicle’s specifications, suspension setup, alignment, tires, and driving conditions.
