Balanced daily comfort with real back-road capability.
Designed to lower your car by approximately 25–30 mm while maintaining composure over real-world roads, the Spec-S sharpens turn-in and body control without beating you up on the commute.
Dežru Spec-S Coilovers – 2019–2025 Audi A6 (C8)
The Dežru Spec-S coilover system is engineered specifically for the 2019–2025 Audi A6 (C8), a larger, stiffer, and more technologically advanced chassis that benefits significantly from properly matched spring rates and modern damper tuning. Designed around the C8’s suspension geometry, curb weight, and Quattro drivetrain, the Spec-S delivers sharper control, improved stability, and increased driver confidence while retaining the refinement expected from a modern Audi sedan.
Developed for drivers who daily their A6 but still enjoy spirited street driving and occasional HPDE track days, the Spec-S features digressive piston valving that provides strong low-speed chassis support during braking, turn-in, and transitions, while remaining compliant over rough pavement, expansion joints, and uneven road surfaces. Rather than chasing excessive stiffness, this setup targets a balanced ride frequency in the ~1.9–2.2 Hz range, tightening the platform and improving feedback without sacrificing comfort or long-distance usability.
Fixed-length damper bodies paired with a 25–30 mm adjustable lowered ride height ensure proper suspension stroke and geometry are preserved. This maintains usable bump travel and predictable roll behavior, allowing the A6 to remain composed, stable, and confidence-inspiring during daily driving and aggressive use alike.
Key Features
-
Digressive monotube dampers for controlled body motion, consistent damping performance, and clear driver feedback.
-
Fixed-length damper bodies with 25–30 mm adjustable lowered ride height to preserve suspension geometry and usable travel.
-
Adjustable damping to fine-tune rebound for daily driving, back roads, or HPDE track events.
-
475 lb/in front and 700 lb/in rear spring rates, selected specifically for the C8 A6 to improve platform control, reduce body roll, and enhance rear stability without introducing harshness.
-
Linear HyperCoil springs for predictable load transfer, consistent response, and smooth behavior throughout the full suspension stroke.
-
OEM-style upper mounts to minimize NVH while maintaining proper fitment and alignment consistency.
-
Hand-built, dyno-matched pairs to ensure precise left-to-right damping consistency.

Performance Character
The Spec-S transforms the Audi A6 C8 by significantly reducing excess body motion and increasing stability without compromising ride quality. The digressive damping profile delivers firm, supportive control during initial inputs and weight transfer, paired with controlled compliance that keeps the tires planted as grip levels rise.
The result is a composed, predictable, and confidence-inspiring driving experience that remains comfortable for daily use, yet stable and responsive when driven aggressively.
