TL-ONE Grip Kit for Toyota GR86 / GT86 / Subaru BRZ

The TL-ONE Grip Kit for the Toyota GR86, GT86, and Subaru BRZ is a complete suspension solution designed to maximize mechanical grip, balance, and consistency. Built around Thunder Lane’s TL-ONE coilover system and paired with adjustable sway bars, this kit addresses the full chassis—not just spring and damper control.

Rather than relying on excessive spring rate to achieve performance, the Grip Kit focuses on usable suspension travel, controlled roll stiffness, and predictable damping behavior. The result is a car that generates grip earlier, maintains balance mid-corner, and remains composed over surface changes.

Fits All GT86 / GR86 / BRZ Generations

This kit is designed to fit all variants of the shared Toyota / Subaru chassis, including:

• Toyota GT86 (ZN6)
• Toyota GR86 (ZN8)
• Subaru BRZ (ZC6 & ZD8)

These platforms share suspension architecture, allowing the TL-ONE Grip Kit to be tuned appropriately for each generation while maintaining consistent performance philosophy.

Built to Order — Tuned to Your Car

Every TL-ONE Grip Kit is built to order. Before anything is assembled, we contact you directly to discuss your goals and vehicle configuration. Spring rates, valving profile, and sway bar setup are selected using real-world factors such as:

• Tire type and size
• Total vehicle weight
• Desired ride height
• Street vs track usage
• Alignment and corner balance goals

This ensures the suspension works as a system, rather than a collection of mismatched parts.

Damping Philosophy & Check Valve Design

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

What’s Included

• TL-ONE monotube coilovers (front and rear)
• 20-click adjustable damping (application-specific)
• Application-specific spring rates
• Fixed-length shock bodies to preserve travel
• Pillowball / spherical bearing upper mounts
• Helper springs (as specified)
• Front and rear adjustable sway bars
• Adjustable sway bar end links
• Electroplated shock bodies and collars

All components are designed to work together to control roll, manage load transfer, and maximize tire contact without unnecessary stiffness.

The TL-ONE Grip Kit is fully rebuildable, serviceable, and re-valvable, allowing the system to evolve as tires, alignment, or driving focus change.

Designed for Grip-Focused Driving

This kit is ideal for drivers who prioritize mechanical grip and balance over raw stiffness. Whether used for street driving, autocross, or track days, the TL-ONE Grip Kit delivers confidence, predictability, and consistent feedback lap after lap.
