TL-PRO Thunder Lane Triple Adjustable Coilover Kit for Mazda MX-5 Miata NA/NB (1990–2005)

The TL-PRO 3-way adjustable coilover system for the Mazda MX-5 Miata NA / NB (1990–2005) is Thunder Lane’s highest-level, build-to-order suspension for drivers who demand repeatable lap time and precise chassis control. Hand-assembled per order in Poland and valved to match your goals—Time Attack, hill climb, autocross, HPDE, or dedicated race use.

True 3-Way Adjustable Damping

Independent adjustment lets you tune the chassis platform separately from impact harshness—ideal for high-grip tires, aero, and long track sessions:

• Rebound – balance, response, and grip on exit
• Low-speed compression – braking support, roll/pitch control, transitions
• High-speed compression – bumps, curbing, surface irregularities

Remote Reservoirs for Heat Control

External reservoirs increase oil volume and cooling capacity for consistent damping under sustained load. Every set is assembled with premium hardware, advanced piston technology, and 46mm monotube dampers with electroplated bodies.

Built to Order — Tuned to Your Miata

Your TL-PRO set is configured around your tires, alignment targets, ride height, corner weights, and intended use. Each order includes CVP & PVP dyno graphs so you can see exactly how the dampers were built.
