This is the kind of Toyota Supra that we deserve

LISTEN 08:25

In the short time that it’s been around, the Toyota Supra has become an aftermarket darling. Tuners have taken to building programs for the A90 Supra with as much fervor as the nameplate commands. Even companies known for building kits for other automakers have turned their attention to the Supra.

Count Manhart Performance on that list. The German house that’s best known for tuning BMW models has prepared a comprehensive program for the Supra that includes an engine upgrade program, suspension tweaks, new wheels, and a host of aesthetic modifications to the exterior and interior. The result is a raunchy Japanese sports car that now lives up to the revered Supra nameplate.

Toyota Supra GR450 by Manhart Performance in Action

Deos the Toyota Supra GR450 Feautre Any Exterior Upgrades?

The short answer is no. Manhart Performance kept the Toyota Supra’s exterior largely intact.

There are no aerodynamic upgrades to speak of; instead, the tuner went the visual route, dressing the Supra up with red accent lines and stripes on the front splitter, side mirrors, and side skirts.

Manhart also added a grey and red racing stripe that runs the length of the Supra, starting from the hood and going all the way to the ducktail spoiler at the back. A fresh pair of 20-inch wheels now occupies the front axle while a slightly bigger pair of 21-inch wheels are now in place at the back. The wheels come in a diamond polish and are available in either gloss black or matte black.

Manhart Performance’s approach is no different from what other tuners have done with their programs for the Supra. Fellow German company AC Schnitzer also kept the sports car’s exterior intact, though it did supply a black-painted front splitter and a carbon fiber rear wing that sat on top of the stock spoiler.

On the other hand, other tuners have taken opposite approaches. EVS Tuning, for example, prepared an extensive aero kit — it came with a massive front splitter and an even more massive rear spoiler, among other bits — for the Supra that came as part of Evasive Motorsports’ wide-body project for the two-door sports car. That vehicle was displayed at the 2019 SEMA Auto Show.

Manhart’s decision to keep the exterior upgrades muted shows us that there are different approaches in preparing aftermarket programs for Toyota’s new prized sports car. These approaches depend on the objectives of each tuner, and as we’ll see later on, Manhart Performance’s objective for the A90 Supra is less about making it look good and more about improving its power and performance capabilities.


Are personalized interior upgrades available upon request?

Yes, they are. Like most tuners these days, Manhart Performance did not prepare specific interior upgrades. This approach has become prevalent in the tuning scene, though it’s not because tuners like Manhart have no attachment to the interiors of the cars they’re building programs for. Tuners have resisted the urge of dressing up the interior of cars with program-specific upgrades because they’re leaving that option open to customers.

Manhart Performance’s program for the A90 Supra is no different. Instead of offering a specific program with no personalization and customization options available, the German tuner is putting that option in the hands of its customers. That’s why it has left the A90 Supra’s interior in stock look with the caveat that potential customers can request for potential upgrades depending on how they want to dress up the interior of the A90 Supra. These customizable upgrades typically range from leather and Alcantara options, as well as carbon fiber bits and whatever other exotic material customers can think of. These upgrades do come at a cost depending on the materials that are chosen.

How Much Power Does the Toyota Supra GR450 by Manhart Have?

Manhart Performance’s engine upgrade program for the Toyota A90 Supra is as extensive as it gets. That shouldn’t come as a shock to people because the Supra is equipped with the same 3.0-liter turbocharged inline-six engine as the BMW Z4 Roadster. Incidentally, Manhart released its upgrade for the Z4 Roadster last year, and, as you might expect, there are some similarities between the two engine upgrade programs.

At the heart of this tuning kit is Manhart’s MHtronik Powerbox kit.

This program, combined with the tuner’s know-how in the art of ECU remapping, is largely responsible for the substantial increase in output coming out of the A90 Supra’s turbocharged inline-six-cylinder engine. Mind you, the sports coupe’s turbo six packs 340 horsepower and 369 pound-feet of torque in stock form. But thanks to the aforementioned MHtronik Powerbox kit, the accompanying ECU remap, and the inclusion of the tuner’s own stainless steel exhaust system with valve control, Manhart Performance was able to squeeze out 450 horsepower and 479 pound-feet of torque. For what it’s worth, Manhart’s engine upgrade program for the Z4 Roadster netted a 440-horsepower output from the Bimmer’s turbo six engine. Advantage (though not by a lot): the Toyota Supra.

How much does the raised output affect the Supra’s performance time?

In standard form, the Supra is capable of sprinting from 0 to 60 mph in just 4.1 seconds to go with an electronically limited top speed of 155 mph. Now, I don’t expect the sports car’s top speed to increase unless the limiter is removed, but as far as the acceleration time is concerned, expect the Supra GR 450 to post a faster time now that it’s packing more horses in that engine. Manhart Performance didn’t specify the time, but somewhere in the vicinity of 3.6 to 3.8 seconds isn’t out of reach.

Does the Supra GR450 have an Updated Suspension?

With the Toyota Supra now packing the kind of power we expected from it, it goes without saying that proper chassis and suspension modifications are needed to ensure that the Supra drives to its new capabilities. On that end, Manhart Performance installed lowering springs sourced from H&R to give the Supra much-needed road balance. If the H&R lowering springs aren’t to your liking, you can opt for three-way coilovers from KW Suspensions instead. Either setup works as intended. The Supra GR 450 is now a bonafide sports car.

Manhart Performance, like most tuners, doesn’t release pricing details off the bat. Part of this is because a program’s price will depend largely on the number of personalization options that a customer avails. The more options a customer gets, the higher the program’s price is going to be. That said, programs of this quality typically cost somewhere in the vicinity of $30,000 to $40,000 depending on the number of options included.

Keep your mind on that price range if you decide to let Manhart Performance work on your Toyota Supra. If you don’t own an A90 Supra and you want to spend for the whole bag, be advised that the Supra starts at around $50,000.

Final Thoughts

I was like most people who were disappointed to hear that the Toyota A90 Supra only came with 340 horsepower. But I’ve warmed up to that figure now that I know what kind of tuning potential the sports car has. It helps, too, that Manhart Performance is behind this specific program.

The tuner’s expertise in building kits for BMW models manifests itself in a positive way with this build. The whole kit is as impressive as you’d expect it to be coming from a tuner that has years of experience in the business. The only downside is the potential costs that you’ll have to pay for the program, but if you can take that hit, you’re going to be rewarded with a version of the Supra that we all wanted in the first place.

  • Leave it
    • Price could go up depending on options
    • Access to Manhart Racing could prove tricky
    • Does the Supra need the upgrade?

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio
