TL-ONE Thunder Lane Track Performance 1-Way Adjustable Coilover Kit for Mazda MX-5 Miata (NC)

NC Miata needs control without harshness. TL-ONE is a built-to-order, 1-way adjustable coilover kit designed to keep the NC planted through braking zones, transitions, and high-load corners—without beating the car up over bumps.

Every TL-ONE set is hand-assembled per order in Poland with premium internal hardware (check valves, advanced piston tech) and ships with CVP & PVP dyno graphs. We’ll contact you to confirm your tire, wheel, ride height target, spring preference, and intended use so we can build a custom valving profile that matches your NC’s weight, grip, and setup.

Why TL-ONE for NC Miata?

The NC is a fantastic track chassis, but it rewards dampers that can manage weight transfer and keep the tire loaded over imperfect surfaces. Generic coilovers often feel overdamped in the wrong places, which shows up as reduced compliance, skittishness over curbing, and inconsistent grip.

TL-ONE focuses on usable travel + stable monotube damping so the car stays composed at pace—especially with wider tires, stiffer bars, and aggressive alignment.

What’s Included (TL-ONE 1-Way Adjustable Kit)

• 46mm monotube dampers built for heat stability and track consistency
• Electroplated bodies for long-term durability
• Fixed-length construction for efficient packaging and travel
• 20-click adjustment for fast, repeatable tuning changes
• Spherical bearing top mounts for precision and feedback
• Dyno graphs included (CVP & PVP)
• Rebuildable/serviceable performance monotube design

Valving, Spring Rates & Setup Support

• Bespoke valving tailored to your use (autocross, HPDE, time attack)
• Spring rate selection help based on tire grip, aero, and balance targets
• Tuning advice for ride height and damping baseline to get you on pace faster

Upgradeable to 3-Way Remote Reservoir

Need more tuning range for slicks, aero, or rougher circuits? TL-ONE can be upgraded to a 3-way remote reservoir setup with low-speed and high-speed compression adjustment.

Best For

• HPDE / Track Days (consistency through long sessions)
• Time Attack (support for high-grip tires + downforce)
• Autocross (responsive without losing compliance)
• Dual-duty street/track builds with correct spring/valving choices
