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

Dial in your ND Miata for real track grip. TL-ONE is a custom-built, 1-way adjustable coilover kit engineered for stable platform control, predictable damping, and the kind of compliance that keeps the tire working on curbing and rough pavement.

Every kit is hand-assembled per order in Poland and ships with CVP & PVP dyno graphs. We’ll confirm your goals (HPDE, time attack, autocross), tire and wheel setup, ride height target, and spring preference, then build a bespoke valving profile to match how your ND is driven.

Why TL-ONE for ND Miata?

The ND responds incredibly well to damping quality—especially once you add grip, alignment, and aero. Many generic coilovers get “busy” over bumps or run out of effective travel at track ride heights. TL-ONE is designed around usable travel and monotube consistency, helping the car stay calm in transitions while maintaining compliance where it matters.

That means better confidence at the limit, improved traction on corner exit, and more stability under threshold braking.

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

• 46mm monotube dampers with excellent thermal stability
• Electroplated bodies for long-term durability
• 20-click adjustment for quick trackside tuning
• Spherical bearing top mounts for crisp response and repeatability
• Dyno graphs included (CVP & PVP)
• Rebuildable/serviceable performance damper design

Custom Valving & Spring Rate Matching

• Valving matched to your tires, aero, and driving priorities
• Spring rate recommendations for dual-duty, HPDE, or full time attack focus
• Guidance to build a baseline setup that’s fast without feeling “spiky”

Upgradeable to 3-Way Remote Reservoir

When you’re ready to push harder, TL-ONE can be upgraded to a 3-way remote reservoir configuration with low-speed and high-speed compression adjustment—ideal for aero cars, slicks, and rougher tracks.

Best For

• HPDE / Track Days (composure and consistency in long sessions)
• Time Attack (platform support with grip and aero)
• Autocross (fast response without sacrificing compliance)
• Serious dual-duty builds with proper spring/valving selection
