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 – 2012–2018 Audi A6 (C7)
The Dežru Spec-S coilover system is engineered specifically for the 2012–2018 Audi A6 (C7), a larger, heavier luxury sedan that demands precise damping control and correctly matched spring rates to truly come alive. Designed around the C7’s suspension geometry, curb weight, and Quattro drivetrain, the Spec-S delivers a substantial improvement in stability, body control, and driver confidence while preserving the refinement expected from an Audi.
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 under braking, turn-in, and transitions, while remaining compliant over rough pavement, expansion joints, and uneven surfaces. Rather than chasing excessive stiffness, this setup targets a balanced ride frequency in the ~1.9–2.2 Hz range, tightening the platform without compromising comfort or long-distance drivability.
Fixed-length damper bodies paired with a 25–30 mm adjustable lowered ride height ensure proper suspension stroke and geometry are maintained. This preserves usable bump travel and predictable roll behavior, allowing the A6 to remain composed, stable, and confidence-inspiring in both daily driving and aggressive scenarios.
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.
-
450 lb/in front and 650 lb/in rear spring rates, selected specifically for the C7 A6 to improve platform control, reduce body roll, and enhance rear stability without harshness.
-
Linear HyperCoil springs for predictable load transfer, consistent response, and smooth suspension behavior throughout the full 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 C7 by dramatically reducing excess body motion and improving stability without sacrificing 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 controlled and responsive when driven aggressively.
