The Infiniti G35 and G37 share their platform with the Nissan 350Z and 370Z, and Thunder Lane's coilovers are built around that shared chassis rather than badge engineering. Every kit uses a true rear coilover configuration — spring and damper together at the rear wheel — for better rear-wheel control and predictability than the factory's divorced-spring layout.
TL-ONE is the single-adjustable option, built around four proven spring/valving baselines depending on whether you're setting up for Track/Race, Street/Track, Comfort, or Drift use. TL-PRO steps up to true 3-way adjustable damping with remote reservoirs and includes front and rear adjustable sway bars, aimed at drivers running aero, high-grip tires, or competing seriously in Time Trials.
Every G35/G37 kit is hand-assembled per order in Poland with CVP and PVP dyno graphs, and can be valved for street use as well as track duty. Lead time is 4–6 weeks.
