Dežru Spec-S Coilovers – Toyota GR Corolla

The Dežru Spec-S coilover system is engineered specifically for the Toyota GR Corolla, a high-output AWD hot hatch with a short wheelbase, aggressive factory tuning, and immense performance potential. Designed around the GR Corolla’s chassis stiffness, AWD torque distribution, and weight balance, the Spec-S delivers substantially improved control, stability, and driver confidence without compromising daily usability.

Developed for drivers who daily their GR Corolla but still enjoy spirited street driving, canyon roads, and occasional HPDE track days, the Spec-S features digressive piston valving that provides strong low-speed support during braking, turn-in, and rapid 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 ~2.1–2.4 Hz range, sharpening response while keeping the car composed and livable on real roads.

Fixed-length damper bodies paired with a 25–35 mm adjustable lowered ride height ensure proper suspension stroke and geometry are preserved. This approach maintains usable bump travel and predictable roll behavior, allowing the GR Corolla to remain stable under hard driving while retaining everyday comfort.

Key Features

Digressive monotube dampers for excellent body control, consistent damping performance, and clear driver feedback.
Fixed-length damper bodies with 25–35 mm adjustable lowered ride height to preserve suspension geometry and usable travel.
Adjustable damping to fine-tune rebound for daily driving, aggressive street use, or HPDE track events.
750 lb/in front and 850 lb/in rear spring rates, selected to control pitch and roll, manage AWD traction, and stabilize the chassis under acceleration.
Linear HyperCoil springs for predictable load transfer, smooth response, and consistent behavior throughout suspension travel.
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 GR Corolla by significantly reducing body roll, tightening transitional response, and improving stability under braking and power application. The digressive damping profile provides immediate chassis support during initial inputs, paired with controlled compliance that keeps the tires planted as grip levels rise.

The result is a GR Corolla that feels planted, predictable, and confidence-inspiring, remaining comfortable for daily driving while delivering the control and composure needed for aggressive street and track use.
