Dežru Spec-RS Coilovers – 2011-2022 Lamborghini Aventador

The Dežru Spec-RS coilover system is the pinnacle of precision for the Aventador chassis — a platform renowned for its purity and razor-sharp handling. Designed around the Aventador’s geometry, the Spec-RS brings uncompromising control and modern race-bred damping technology to an already exceptional sports car.

Developed for serious enthusiasts and weekend track drivers, the Spec-RS features digressive piston valving that delivers exceptional chassis support under load while maintaining compliance over uneven pavement. Combined with external rear reservoirs, this system achieves superior thermal consistency and fade resistance during extended lapping or canyon sessions.

With fixed-length damper bodies and a 30–45 mm adjustable lowered ride height, the Spec-RS maintains proper stroke, geometry, and roll center correction — ensuring the car feels composed and confidence-inspiring at every corner entry and exit.

Key Features

Digressive monotube dampers for superior control, consistent damping, and precise driver feedback.
External reservoirs for improved heat dissipation and fade-free performance during continuous high-load use.
Fixed-length damper bodies with 30–45 mm adjustable lowered ride height for optimal geometry and bump travel retention.
Adjustable damping to fine-tune rebound for street, canyon, or track conditions.
400 lb/in front & 525 lb/in rear spring rates — perfectly balanced for fast road + HPDE driving.
Linear HyperCoil springs ensure predictable response and smooth load transition through each phase of the corner.
Pillowball front top mounts for sharp steering feedback and alignment consistency.
Hand-built, dyno-matched pairs to ensure precise left-right damping uniformity.

Performance Character

The Spec-RS elevates the Aventador’s natural balance and steering precision while offering vastly improved chassis composure under braking, transitions, and sustained cornering loads. The digressive valving curve provides firm, supportive damping on compression with a smooth, compliant rebound response — ideal for high-grip tires and spirited driving.

Expect a flat, confident, and responsive feel on turn-in, with the compliance and traction to put power down hard out of every corner — lap after lap.

Why We Recommend 400 lb/in Front & 525 lb/in Rear for the Lamborghini Aventador

The Lamborghini Aventador is a mid-engine, all-wheel-drive platform with a rear-biased weight distribution and a rigid pushrod-style suspension system. While the factory setup is engineered for high-speed capability, it is still tuned to balance road comfort with performance, which can limit precision and consistency when pushed aggressively.

Our 400 / 525 spring rate setup is designed specifically for Spec-RS, where the focus is improving chassis control, sharpening response, and increasing confidence at higher limits without compromising the car’s inherent balance.

With the Aventador’s rear-biased weight distribution and high power output, the rear of the car experiences significant load during acceleration and high-speed cornering. The 525 lb/in rear spring provides the support needed to stabilize the rear platform, reduce excessive compression, and maintain consistent geometry under load. This improves traction, stability, and predictability when driving at speed.

Up front, the 400 lb/in spring is carefully selected to maintain front-end grip while improving control under braking and turn-in. It reduces dive and keeps the front end composed without over-stiffening, which is critical for preserving steering feel and front tire contact on a high-performance AWD system.

The result is a setup that:

Improves high-speed stability and overall chassis control
Reduces pitch and excessive movement under load
Enhances balance between front and rear grip
Increases confidence and precision during aggressive driving

This pairing is designed to work with our Spec-RS valving, which delivers strong low-speed damping for immediate response and increased high-speed control for track and high-speed environments. The combination of spring and damping creates a more direct, connected feel without making the car unpredictable or overly harsh.

Compared to softer, street-oriented setups, this configuration prioritizes precision and stability, making it ideal for drivers who want a more controlled, performance-focused Aventador for spirited driving and track use.

Overall, 400 front / 525 rear gives the Aventador a more stable, balanced, and confidence-inspiring character, enhancing its ability to perform at high speeds while maintaining control and predictability.
