The Mazda MX-5 Miata NC TL-ONE Coilover System is Thunder Lane's built-to-order, 1-way adjustable coilover for the 2006–2015 Miata — hand-assembled in Poland to keep the NC planted through braking zones, transitions, and high-load corners without beating the car up over bumps.
Built for Racing, Time Attack, Autocross, and HPDE
The NC rewards dampers that manage weight transfer and keep the tire loaded over imperfect surfaces — TL-ONE focuses on usable travel and stable monotube damping so the car stays composed at pace with wider tires, stiffer bars, and aggressive alignment. Every kit can also be valved specifically for street use — the compliance needed for competent track use often makes for a comfortable street ride, since controlling the platform better also controls body motion better on the street.
Technical Specs
- 46mm monotube dampers, built for heat stability and track consistency
- 20-click rebound adjustment (1-way)
- Ride Height Adjustment (fixed-length construction for efficient packaging and travel)
- Spherical bearing top mounts
- CVP + PVP dyno graphs included with every kit
Construction & Hardware
Check valves and advanced piston design manage the split between compression and rebound for consistent performance under heat. Electroplated bodies resist long-term corrosion, and every kit is rebuildable and serviceable — with a path to upgrade to 3-way remote-reservoir damping later.
Fitment
Mazda MX-5 Miata NC, 2006–2015.
