Best Coilovers for the Toyota GR Supra A90: TL-ONE & TL-PRO Guide
If you're looking for the best coilovers for the Toyota GR Supra A90, you've already figured out what most owners learn after their first track day: the chassis is capable of far more than the factory dampers allow. Thunder Lane builds two systems for this platform — the single-adjustable Supra A90 TL-ONE Coilover System and the true 3-way Supra A90 TL-PRO Coilover System. Both are hand-assembled in Poland, built to order, and valved to your exact spec — street, HPDE, time attack, or autocross. This guide walks you through which one belongs under your Supra.
Why the A90 Supra Benefits From Proper Coilovers
The GR Supra is a genuinely fast car out of the box — stiff structure, wide track, and a torque-rich straight-six that will find every weakness in your suspension. The factory adaptive dampers do a respectable job on the street, but they're a compromise tuned for a broad audience. Push the car on circuit and you'll feel it: floaty transitions under trail braking, inconsistent platform under power-down, and no way to tune the balance yourself.
A purpose-built coilover changes the equation. Because every Thunder Lane kit is valved to order, your dampers arrive matched to your spring rates, your tire, your weight, and your use case — not a generic "sport" curve. Each set ships with its own CVP and PVP dyno graphs, so you can see exactly what your dampers do before they ever touch the car.
TL-ONE vs TL-PRO: Which to Pick
TL-ONE — single-adjustable, custom valved
The Supra A90 TL-ONE (from $2,617.31, or $2,917.31 with the Swift spring option) is the right answer for most drivers. You get 20 clicks of rebound adjustment on a damper that's already compression-valved to your exact specification. Because the hard work is done on the dyno before shipping, a single rebound knob is all you need to fine-tune for a bumpy back road versus a smooth circuit. If you daily the car and run a handful of HPDE weekends a year, the TL-ONE covers you.
TL-PRO — true 3-way with remote reservoirs
The Supra A90 TL-PRO (from $5,839.75, or $6,239.75 with Swift springs) is the flagship: a true 3-way adjustable system with independent rebound plus low-speed and high-speed compression circuits — 20 clicks of rebound, 34 clicks of low-speed compression, and 22 clicks of high-speed compression. The A90 kit runs inverted dampers front and rear for stiffness under lateral load, and the remote reservoirs use quick disconnects for painless installation and corner-weighting. If you chase lap times, run time attack, or want to separate curb compliance from platform control, this is the tool. Browse the full TL-PRO collection to see how the range is built.

Ride Height: Street vs Track Setup
Both kits are height-adjustable, so you can run a sensible street drop that clears driveways and keeps geometry happy, or drop the car to a track-focused height for events. The honest advice: set ride height once for your primary use, corner-weight the car, and then do your tuning with the clickers rather than the perches. On a TL-ONE that means rebound; on a TL-PRO you can soften high-speed compression for curbs at one circuit and firm the low-speed circuit for transitions at the next — without touching ride height.
Fitment
These systems are built specifically for the Toyota GR Supra A90 platform and are assembled to order for your exact car and spec. Because every kit is built to order, plan around the 4–6 week lead time. Shipping is free to the US, Canada, Mexico, and Central America.

FAQ
How long does a Supra A90 kit take to build?
Every kit is hand-assembled in Poland and valved to your spec, so lead time is 4–6 weeks from order to dispatch.
Can I daily drive the TL-ONE or TL-PRO?
Yes. Because valving is custom, tell us the car is street-driven and we'll build the compression curve around real-world roads. Both kits are rebuildable, so they're a long-term investment rather than a consumable.
What's the difference between the spring options?
Faulkner is the standard spring; Swift is an optional upgrade ($2,917.31 on the TL-ONE, $6,239.75 on the TL-PRO).
Do I get proof of the valving?
Yes — every coilover ships with its own CVP and PVP dyno graphs, so you can verify each damper's behavior and re-check it after future rebuilds.
