The Most Popular Toyota Supra Mk5 Mods | A90 Upgrades in 2025

The Toyota Supra Mk5 A90 is one of the most exciting sports cars manufactured by Toyota. The A90 Supra, as it’s known, offers plenty of power, excellent handling, amazing overall performance, and an attitude fit for sports car royalty. But, believe it or not, it can get better. Way, way better.

If you own a Mk5 Supra, there are certain mods you can install to blow this car’s stock form out of the water. We’re talking about taking its aesthetics, performance, and power to the next level. In this article, we share the eight most popular Toyota Supra Mk5 mods you should consider.

The Best Supra Mk5 Mods in 2025

1. GT Wing

One of the most popular mods for the Toyota Supra Mk5 is a GT wing to plant its rear on the track and transform its performance at high speeds. We recommend one from HKS, as the company is committed to providing well-integrated, reliable, and environmentally sound performance systems.HKS performance parts are user-friendly and easy to install. A GT wing is an amazing upgrade as it improves the aerodynamics of your car.

Features:

• Materials: Fiber Reinforced Plastics

• This product is designed for optimal downforce in the ultra-high-speed range by conducting tests on high-speed circuits.

2. Turbocharger

The Mk5 Supra is already pretty darn quick, with its stock form jumping to 60 in under 3.9 seconds. But, a little bit (okay, a lot) more power isn’t a bad idea. And while the stock turbo has been shown to reliably push to major horsepower numbers, a turbo upgrade can be an even bigger boost.

We recommend a Turbocharger from Pure Turbos, as the brand is known for being an industry leader when it comes to performance turbochargers. The Pure800 Turbo Upgrade for the Toyota Supra MK5 is of high quality, and the kit is guaranteed to improve the efficiency and power of your engine.

Features:

• Paired with the stock engine and transmission, the PURE800 turbo, downpipe, and tune make almost 700whp
• Low boost around 20psi made 559whp, 552whp, and 527whp

3. ECU Flash

Want to unlock the beast in your stock setup without spending a ton of money on aftermarket parts? We recommend the VR Tuned ECU Flash Tune. We’ll tune your Supra’s entire map range, boosting it to some very impressive numbers on both 91 and 93+octane.

This ECU Flash will increase boost pressure, adjust fuel and timing, change torque limiters, and more. Our ECU flash helps to keep your warranty safe while unlocking hidden horsepower and torque gains, enhancing driving characteristics, and throttle response.

4. Dual Tip Muffler

This is also one of the top mods for the Mk5. We recommend a product by HKS again: the HKS Stainless Steel Dual Tip Muffler Toyota Supra. This product is a reliable and environmentally sound performance system.

This muffler from HKS was designed by monitoring consumer reaction and input on material quality, external appearance, sound quality, and of course, performance issues, so you can rest assured that it will deliver on all fronts. This product is designed to be user-friendly and very easy to install.

• Stock Noise Level: 88db / idle: 58db (sport mode)

5. Wheels

There’s a reason that wheels are among the top upgrades for this vehicle. The right set of them could turn heads on the road.

At Vivid, we love the look of a set of BBS LM wheels on a Supra A90, as they’re a perfect wheel package for the body. The 20×10 and 20×11 give the Supra a nice stance, and they’re available with a Satin Bronze finish. They’re forged, optimizing the stiffness-to-weight ratio while providing the safety and long-term durability expected from BBS.

If BBS wheels aren’t your bag, check out the VR Forged D03-R Wheel Package available in Matte Black. The VR Forged D03-R monoblock wheels have a motorsports-inspired ring and are incredibly strong. This wheel is perfectly matched to any “tuner” style vehicle.

6. Steering Wheel

A steering wheel upgrade will change the interior of your vehicle for the better, and since we manufacture our own, why not suggest them? Vivid Racing’s steering wheel upgrade brings about proper ergonomics and a luxury feel that the OEM steering wheel simply does not have. 

Our steering wheel upgrade features beefier hand grips at 9 and 3 positions, giving you proper driving ergonomics. There are a ton of options you can configure, such as a colored 12 o’clock ring, matching stitching, leather, carbon fiber, perforated leather, Alcantara, and more. Because these are made off a factory steering wheel core, you retain your original buttons and trim along with reusing your airbag.

This is not a simple cover. It’s a better-engineered steering wheel.

Specification:

• 12 O’Clock Stripe and stitching in tri-color Toyota red, orange, and yellow stitching
• Black Alcantara hand grips
• Glossy black carbon fiber center trim
• Shift Light

7. Aero & Body Kit

The Supra is beautiful, but it can get even better looking by choosing aftermarket parts that complement its original body lines, such as our favorite kit from AimGain. Made from FRP, Japan, this aero set looks awesome and will also improve your Supra’s aerodynamics.

The AimGain aero kit is available at different prices depending on the parts you want. Some of the parts available include Front Spoiler, Sideskirt, Rear Side Skirt, Rear Diffuser, and Roof Spoiler.

If that set isn’t what you would like for your Toyota Supra Mk5, check out this widebody by Pandem. The Pandem Rocket Bunny Full Wide Body Aero Kit has incredible style, and the design pays careful attention not to ruin key features of the original car’s design. The aero kit enhances the look of the already-stunning A90 Supra, and it definitely exceeds the standard. Choose this design and you’ll stand out from the crowd.

8. Race Downpipe

The last (but not least) popular upgrade for the Supra is a race downpipe. The AMS Performance MKV Toyota Supra Stainless Steel Race Downpipe is a 4.5” full mandrel-bent downpipe with excellent flow.

With this AMS downpipe, power comes in earlier, and turbo spool-up is significantly improved. The long, gradual transitions within the mandrel-bent pipe allow exhaust gases to maintain velocity without a buildup of back pressure inside the system. This downpipe by AMS performs better and isn’t prone to cracking like the alternatives offered by some of the competition.

Features:

• Significantly lower back pressure means the potential for more power
• Exhaust gas can more easily flow across the turbine wheel
• Throaty exhaust note under wide open throttle
• CAD-engineered for maximum exhaust flow with unrivaled fit and finish
• 304 stainless steel 4.5″ design reduces to a 3.5″ flex section, maximizing volume and flow
• The turbine flange offers a smooth transition from the turbine outlet
• 3.15″ (80mm) outlet allows you to run either stock or aftermarket cat-back systems
• Complete bolt-on means no cutting – bolts to the factory location
• O2 sensors in OEM locations, no jumpers needed
• Mandrel-bent tubing for the best flow

Kit Includes:

• Fully stainless steel downpipe
• Adjustable mounting bracket
