Description
The Dežru Spec-S Coilover System is engineered for the Audi A6, offering a performance-focused suspension upgrade designed to improve chassis control, stability, and driver confidence while retaining everyday usability. Developed for drivers who use their A6 as a daily vehicle but also enjoy spirited street driving and occasional HPDE track days, the Spec-S aims to deliver a more composed and responsive driving experience.
Featuring digressive monotube dampers, the Spec-S is designed to provide controlled body movement during braking, cornering, and directional transitions while maintaining compliance over uneven road surfaces. Its damping characteristics prioritize low-speed chassis support to help the vehicle feel more controlled during steering inputs and changes in load. The system targets a ride frequency of approximately 1.9–2.2 Hz, aiming to balance suspension control with the comfort expected from a refined sedan.
The fixed-length damper bodies are paired with an adjustable lowered ride height of approximately 25–30 mm, providing a lower stance while targeting appropriate suspension travel within the intended operating range. Combined with linear HyperCoil springs and OEM-style upper mounts, the Spec-S offers a suspension package designed for everyday driving and occasional performance use.
With 500 lb/in front and 700 lb/in rear spring rates, this configuration is intended to provide additional suspension support for a more controlled chassis response. The linear springs work with the digressive dampers to deliver predictable suspension behavior during braking, cornering, and rapid directional changes.

Performance Character
The Dežru Spec-S is designed to improve the Audi A6's composure by providing more controlled suspension response during braking, cornering, and directional transitions. Its digressive damping profile aims to deliver support during initial steering inputs while maintaining compliance over imperfect road surfaces.
The 500 lb/in front and 700 lb/in rear spring combination creates a firm, performance-oriented setup intended to provide additional suspension support. The front spring rate targets controlled response under braking and turn-in, while the rear rate contributes to the overall suspension balance.
Actual handling characteristics depend on the vehicle's suspension geometry, spring mounting arrangement, drivetrain configuration, alignment, tire selection, and damping adjustments. Correct setup is important for achieving the desired balance between everyday comfort and performance driving.
The result is a suspension package aimed at Audi A6 owners seeking a lower stance and more controlled handling while retaining practical street usability.
Who Is the Dežru Spec-S For?
The Dežru Spec-S is intended for Audi A6 owners seeking a performance-focused suspension setup for:
-
Daily driving with a firmer, more controlled ride
-
Spirited street and back-road driving
-
Improved chassis support during braking and cornering
-
Occasional HPDE and performance driving events
-
A lowered stance with adjustable damping
