Best Coilovers for the Nissan 370Z & Infiniti G37: TL-ONE & TL-PRO Guide

If you're hunting for the best coilovers for the Nissan 370Z and Infiniti G37, you've really got two questions to answer: how adjustable do you want your dampers to be, and how hard do you plan to lean on them? Thunder Lane builds two systems for this chassis — the single-adjustable TL-ONE Coilover System and the true 3-way TL-PRO Coilover System. Both are hand-assembled in Poland, built to order, and valved to your exact use case, whether that's street, track, time attack, autocross or drift.

Why the 370Z and G37 Deserve Real Coilovers

The Z34 370Z and its Infiniti G37 sibling share one of the best front-engine, rear-drive platforms of their era: a stiff shell, proper double-wishbone-style front geometry and a chassis that responds beautifully to spring rate and damping changes. That's exactly why generic one-size-fits-all suspension feels like such a waste on these cars. A soft, universally-valved kit leaves grip on the table; an overly stiff one beats you up on the street without actually going faster.

Thunder Lane kits take the opposite approach. Every set is built to order and valved to the spring rates and driving discipline you choose, so the damper is matched to the spring instead of vaguely tolerating it. You finalize spring rates with us before production begins — nothing ships until the spec is right for your build.

TL-ONE vs TL-PRO: Which Should You Pick?

TL-ONE — single-adjustable, seriously capable

The Nissan 370Z/Infiniti G37 TL-ONE (from $2,320.31) is the sweet spot for most owners. It's a true rear coilover with 20 clicks of rebound adjustment, letting you firm things up for a track day and soften them off for the drive home with one knob per corner. If you daily the car, run HPDE weekends or autocross, and want a kit you can actually understand and tune, this is the one. Browse the full TL-ONE range here.

TL-PRO — true 3-way for drivers chasing tenths

The Nissan 370Z/Infiniti G37 TL-PRO (from $4,696.88) is Thunder Lane's highest-level system for this chassis: independent rebound plus low-speed and high-speed compression adjustment, with remote reservoirs. That separation matters when you're tuning for curbs, compressions and tire loading independently of body control. It's the choice for time attack, serious track builds and competition drift cars. See everything in the TL-PRO collection.

Specs That Matter

• 46 mm electroplated monotube bodies — fully rebuildable, so the kit is a long-term investment, not a consumable.
• CVP + PVP dyno graphs supplied with your dampers, so you can see exactly how your set was valved.
• Spring rate options straight from the configurator: 14k F / 6k R (comfort), 16k F / 7k R (street/track), 20k F / 8k R (track/race) and 16k F / 10k R (drift), with Faulkner springs standard and Swift springs available as an upgrade.
• 6-month warranty and a 4–6 week build-to-order lead time.
• Free shipping to the US, Canada, Mexico and Central America.

Ride Height: Street vs Track

Both systems give you full ride height control. For a street car, we suggest a conservative drop that preserves suspension travel and keeps the splitter off driveways; for track use, you can go lower and stiffer, then dial the geometry to match. Ride height and alignment work together on this chassis — once your kit is installed, read our track alignment basics guide for the 350Z, G35, 370Z & G37 to get camber and toe working with your new setup rather than against it.

Fitment

Both kits are built specifically for the Nissan 370Z and Infiniti G37 platform — no adapting, no guesswork. Because every set is made to order, your spring rates, valving and spec are confirmed with you before production starts. Shopping the wider lineup?

FAQ

Can I daily drive these coilovers?

Yes. Choose the softer spring options (14k/6k or 16k/7k) and the valving is matched to them. The TL-ONE's 20-click rebound adjustment lets you run a compliant street setting and stiffen up for track days.

What spring rates should I order?

Tell us how you use the car — street, HPDE, time attack, autocross or drift — and we'll finalize spring rates with you before your kit goes into production. Nothing is built until the spec is agreed.

How long until my kit ships?

Every kit is hand-assembled in Poland to your order, with a typical lead time of 4–6 weeks. Shipping is free to the US, Canada, Mexico and Central America.

Are the dampers rebuildable?

Yes — the 46 mm electroplated monotube bodies are fully rebuildable and revalveable, so the kit can evolve as your build does. Every kit carries a 6-month warranty.

Ready to Build Yours?

Pick your platform, pick your tier, and let's spec it together: the TL-ONE 370Z/G37 system for street-and-track versatility, or the TL-PRO 370Z/G37 system when only a true 3-way will do. Every kit is valved to your spec, dyno-documented, and built for you in Poland.
