The TL-ONE coilover system for the Toyota GR Supra A90 is designed for drivers who want a suspension that performs equally well on the street and the track. Built around predictable damping behavior and usable suspension travel, TL-ONE delivers confidence, compliance, and consistency without unnecessary complexity.

TL-ONE is built to order and configured specifically for the A90 chassis, using proven spring rates, inverted damper architecture, and application-specific valving to support modern tire grip and chassis dynamics.

Designed for Street and Track

This system is engineered to balance ride quality, control, and performance. Whether driven daily, used for weekend canyon runs, or pushed on track, TL-ONE maintains stability and composure without relying on excessive stiffness.

Inverted Monotube Damper Design

TL-ONE for the Supra A90 features inverted front struts and inverted rear shocks. This design increases rigidity under load, improves durability, and delivers more consistent damping behavior during aggressive driving.

Damping Philosophy & Check Valve Design

TL dampers utilize an internal check valve system that helps manage how damping forces are distributed between compression and rebound. This allows strong low-speed control for chassis stability while maintaining compliance over bumps and surface irregularities.

1-Way Adjustable Damping

TL-ONE features 20-click rebound damping adjustment, providing meaningful tuning changes for balance, grip, and response without overcomplicating setup.
