Best 2020-2024 Toyota GR Supra Coilovers (A90 Guide)

The best coilovers for the 2020–2024 Toyota GR Supra (A90) are the KW Clubsport 2-Way for track-focused drivers and the KW Variant 3 for street-and-track dual duty — both deliver independent compression and rebound damping that the factory Adaptive Variable Suspension cannot match. The A90 Supra is a genuinely fast car, with the 3.0L B58 turbo inline-six making 382 horsepower and 368 lb-ft of torque in 2021 and later cars (335 hp in 2020) and a 0–60 mph time of 3.9 seconds. But at roughly 3,400 pounds with a soft factory ride-height and comfort-biased damper tune, the stock suspension is the first thing serious drivers replace. This guide compares the coilovers, lowering springs, and sway bars we sell and install at NLP Performance in Tampa, FL, with real spring rates, lowering ranges, and prices.

Why the A90 GR Supra Needs a Suspension Upgrade

The 2020–2024 GR Supra ships with Adaptive Variable Suspension (AVS) — electronically controlled dampers that continuously switch between comfort and sport firmness. It is a good system for a factory car, but it locks you into Toyota's ride height and a fixed range of damping. Enthusiasts hit its limits fast: noticeable body roll on turn-in, a tall fender gap, and a rear axle that gets loose when you push a chassis that shares its bones with the BMW Z4 (G29). The Supra uses a MacPherson-strut front and multi-link rear, a layout that responds dramatically to a proper coilover.

A coilover conversion does three things at once: it lowers the car's center of gravity, adds real spring rate to control that 3,400-pound mass, and — on a 2-way kit — lets you tune compression and rebound independently for the surface you are on. The payoff is measurable: flatter cornering, quicker transient response, and a stance that finally fills the wheel wells. Below are the kits we stock and install, ranked by how most A90 owners actually use them.

Best GR Supra Coilovers and Suspension Upgrades (2020–2024)

Every kit below is confirmed to fit the A90 GR Supra 3.0 (the same hardware also covers the 2019+ BMW Z4 sDrive M40i it shares a chassis with). We list the real spring rates, damping adjustment, and lowering range for each so you can match the setup to how you drive.

1. KW Clubsport 2-Way — Best Overall Coilover

The KW Clubsport 2-Way is our top pick because it is a true motorsport coilover that is still road-legal (TÜV-approved in Germany) and was developed on the Nürburgring Nordschleife. It uses independent low-speed compression (12 clicks) and rebound (16 clicks) adjustment, so you can firm up body control for a track day and soften it back down for the drive home. Front spring rate is 340 lb/in and rear is 800 lb/in, and the kit ships with camber-adjustable top mounts — a critical detail for dialing in front grip on a chassis that likes negative camber.

2. KW Variant 3 (with Electronic Dampers) — Best for Adaptive-Suspension Cars

If your A90 has the factory adaptive dampers (nearly all 3.0 cars do), the KW Variant 3 with electronic-damper compatibility is the cleanest install. It plugs into the AVS wiring so you keep the factory dash controls and avoid warning lights — no separate canceller needed. Like all V3 kits, it offers independent adjustment with 12 clicks of compression and 16 clicks of rebound, plus a stepless lowering range of roughly 0.6–1.4 in front and 0.8–1.6 in rear. It is built in Germany from stainless steel for corrosion resistance.

3. KW Variant 3 (Standard) — Best Value Coilover

The standard KW Variant 3 delivers the same German-built damper technology and independent compression/rebound adjustment as the electronic version, at $3,474.00. It is the right call for A90 owners who either do not have the factory adaptive dampers or plan to run a KW Electronic Damping Cancellation kit (below) to defeat the AVS trouble codes. This is the sweet spot for a street-and-canyon Supra that visits the track a few times a year.

4. H&R Sport Springs — Best Budget Lowering

Not everyone needs a $4,000 coilover. H&R Sport Springs ($398.65) are a progressive-rate lowering spring that reuses the factory AVS dampers — the cheapest way to kill the fender gap and reduce body roll while keeping the adaptive ride. They drop the A90 Supra 1.0 in front and 0.75 in rear, a moderate, street-friendly stance that pairs well with an alignment. This is the entry point to a better-handling Supra for well under five hundred dollars.

5. KW Electronic Damping Cancellation Kit — The Essential Add-On

If you fit a non-electronic coilover (like the standard KW V3) to an A90 with adaptive dampers, the car will throw a persistent suspension fault. The KW Electronic Damping Cancellation Kit ($493.95) solves it — KW is the only manufacturer that shuts down the factory damper regulation and simultaneously suppresses the trouble codes, keeping your dash clean. Budget for this alongside any standard (non-electronic) coilover on an AVS-equipped Supra.

Chasing the drag strip instead of the road course? The HKS Hipermax Max IV SP ($3,500.00) is a drag-tuned full coilover kit built specifically for the 2020+ GR Supra MkV. And if you keep the factory springs but want to attack understeer, a set of adjustable sway bars is the highest-value handling mod on the car — see the Eibach anti-roll kit below.

GR Supra Coilovers Compared

Here is how the leading 2020–2024 GR Supra (A90) suspension options stack up on type, adjustability, and price. Every product name and price links straight to its page.

Coilovers vs Lowering Springs for the GR Supra

Coilovers are the better choice if you want adjustable ride height and damping; lowering springs are the better choice if you want a lower stance for the least money while keeping the factory dampers. A coilover like the KW V3 replaces the entire strut assembly, so you set exactly how low the car sits and how firm it rides — ideal for track use or a precise corner-balanced setup. Springs like the H&R Sport set simply swap the coils, lowering the A90 a fixed 1.0 in front / 0.75 in rear and relying on the stock AVS struts for damping. If your Supra is a weekend canyon car or occasional track toy, spend on coilovers. If it is a daily driver you just want to sit right, springs get you 80 percent of the look for roughly one-eighth the price.

Does the Supra's Adaptive Suspension (AVS) Complicate the Install?

Yes — the A90's Adaptive Variable Suspension is the single most important thing to plan around when buying coilovers. Fit a non-electronic coilover to an AVS car and the ECU logs a damper fault and lights the dash. You have two clean paths: buy a coilover engineered to retain the electronic dampers (the KW V3 with electronic-damper compatibility plugs right in), or run a standard coilover plus the KW Electronic Damping Cancellation Kit to shut the codes off. H&R Sport Springs sidestep the issue entirely because they reuse the factory adaptive struts. Confirm whether your car has adaptive dampers before ordering — it changes which kit is correct.

Installation and Alignment Notes

Plan on a professional install and a corner-balanced alignment for any coilover on the A90 Supra. In our Tampa, FL shop, a coilover swap is typically a half-day job, and we always follow it with an alignment because lowering the car changes camber and toe — skipping it eats tires fast. The KW Clubsport's camber-adjustable top mounts let us add front negative camber for grip; on springs or fixed-top-mount kits we use aftermarket camber arms if the numbers fall out of spec. Set ride height first, then corner-balance, then align — in that order — for a Supra that drives as good as it looks.
