A90 Supra Coilovers Arriving Soon!!!

Finally! It’s been an exhausting R&D process in getting a coilover available for the newest Toyota Supra. But now we can say it’s an honest improvement to the OEM suspension.

That was the hiccup in getting our coilovers released in a timely manner. While we had early access to the A90 Supra working with Toyota Motorsports in the U.S., this new platform proved to be difficult in getting to actually improve its performance on just suspension alone. But now, with the help of Japanese sports car tuner Matchless Crowd Racing (MCR), we finally have something to offer!

STREET ADVANCE Z (Part number: GSTJ4-91AS3)

MSRP: $1,200.00

After nearly two years of R&D on this car, we’re first releasing our STREET ADVANCE Z coilover kit. At $1200 retail, this kit is a great value in high performance suspension for this new car.

Geez. Two years… Why did it take so long?! We won’t go into all the details. After all, if you’re an A90 Supra owner, we really don’t want to say much to offend you. But since you’re reading this, I’d wager in my assumption that you’re looking to increase the handling performance of your car. So…… In a word, it’s a very difficult car to work with. Don’t take our word for it. If you do a quick search on “MCR A90 Supra” you’ll quickly find that MCR’s owner, Kobayashi-san, really doesn’t like the new Supra. According to him, in translated text, It can’t turn, can’t stop, and is slow. Those are supposed to be aspects that a sports car is good at!

Take it for whatever it’s worth. I happen to like the A90, but maybe the criticism of this car is just simply a tuner’s standpoint (or marketing point) in order to give the aftermarket something to work with and give the end-user something they “need”, if you know what I mean.

The fact is, the new Supra isn’t priced anywhere near other Japanese supercars like the Acura NSX or Nissan GT-R, and for good reason- it simply isn’t built like those cars. It seems like it was built with aftermarket tuning in mind.

But, it is true- the new Supra is a difficult one. It’s very electronically-laden, much like a lot of high-end sports cars these days. And, again no offense, it is very typical German engineering. That’s not a bad thing. It just takes some time to better understand their design to really improve upon it.

So, what do you get with our A90 STREET ADVANCE Coilover Kit?:


-6kg/mm front springs

-12kg/mm rear springs

-Damping adjustability (16-click rebound) for front and rear dampers

-Rear upper mounts with access holes for damping adjustment

-TEIN Developed Error Canceller Units

-Camber Adjustable Upright Insert

A few things to explain-


Our Error Canceller makes this a plug ‘n play suspension kit by connecting directly to the OEM’s Electronic Suspension control module. Without it, and simply unplugging the OEM dampers will cause a warning on your dash.

Example of TEIN Error Canceller

Our Camber Adjustable Upright Insert is a sleeve between our damper and the aluminum knuckle assembly. By allowing camber adjustment from the bottom of the strut, you can retain the OEM upper mount assembly, which is a good design in reducing NVH.

While installation of our coilovers do void the use of the Factory Electronic Suspension system, you can opt for our optional EDFC ACTIVE or EDFC ACTIVE PRO kit to allow for electronically controlled damping settings.

At last, we finally have a setup that offers true handling performance gains for the new Supra. Better late than never, and better to be well-developed than hastily done, I suppose. Anyway, expect this kit to arrive mid June 2021!
