The Icon Reborn: Refining the Toyota GR Supra (A90/A91)
The Toyota GR Supra (A90) marks the return of a legend. Powered by the brilliant BMW B58 engine, it offers incredible performance out of the box. However, like any modern sports car, it is restricted by factory compromises. The exhaust is muted, the cooling system struggles on the track, and the stance is conservative. ATOMIC-SHOP offers a carefully curated selection of premium upgrades to unlock the true character of your Supra, making it faster, louder, and sharper.
Breathing Fire: Intake & Exhaust
The B58 engine is a masterpiece, but it needs to breathe freely to reach its full potential.
Eventuri Carbon Intake
This is arguably the most popular and effective modification for the A90 Supra. The Eventuri Intake System is not just an air filter; it's a completely re-engineered airflow path that smooths out turbulence and significantly lowers intake temperatures. Plus, it unleashes the glorious turbo spool sound that is muffled by the stock airbox.
Akrapovič Titanium Exhaust
Transform the sound of your Supra from a hum to a roar. The Akrapovič Slip-On Line saves weight and adds a deep, sophisticated tone. For maximum performance, the Evolution Link Pipe removes restrictive filters, unlocking true straight-six music.
Cooling: Solving the B58's Weakness
The B58 runs hot, especially in high-ambient-temperature environments. For track use or spirited driving, managing heat is critical.
CSF Cooling Package
The factory cooling system is adequate for the street but can struggle on the track. We recommend the CSF High-Performance Heat Exchanger and Auxiliary Radiators. These all-aluminum units provide a massive increase in cooling capacity, preventing heat soak and ensuring the engine delivers consistent power run after run.
Suspension & Handling: Sharpening the Chassis
The Supra's chassis is rigid, but the suspension can be refined for better feedback and a more aggressive stance.
- KW & Öhlins Coilovers: Get the perfect balance between track performance and street comfort. KW V3 and Öhlins Road & Track coilovers allow for full adjustment of damping and ride height, eliminating body roll in corners.
- Eibach Springs: For a cost-effective upgrade, Eibach Pro-Kit springs work with factory adaptive dampers to lower the center of gravity while maintaining excellent ride quality.
Braking: Stopping the Beast
With increased power comes the need for superior stopping performance and thermal resistance.
Girodisc & Pagid
Upgrade to Girodisc 2-piece floating rotors to save unsprung weight and improve cooling efficiency. Pair them with Pagid or Endless brake pads for fade-free performance during intense track sessions.
FAQ: Toyota GR Supra Upgrades
What is the benefit of the Eventuri intake besides looks?
The patented Venturi housing accelerates airflow into the turbo, improving throttle response. On tuned cars, it can add 15-20hp by removing airbox restrictions and dramatically amplifying the turbo induction sound.
Will modifying my Supra void the warranty?
"Bolt-on" parts like intakes and exhausts generally do not void the entire warranty. However, ECU tuning or removing catalytic converters can affect powertrain warranty claims. Always consult with your local specialist or dealer.
Why do I need a heat exchanger upgrade?
The A90 Supra uses a water-to-air intercooler system. The "heat exchanger" is the radiator for this system. The CSF unit is larger and keeps the water colder, which directly results in lower intake air temperatures and prevents power loss due to heat.
What wheels fit the A90 Supra?
The Supra uses a 5x112 bolt pattern. We offer specific fitments from Advan and BBS designed to clear large factory brakes and sit flush with the fenders without the need for spacers.
