What are the top modifications for improving performance on a Toyota GR86?

I just purchased a Toyota GR86 and I want to know what modifications I can make to improve its performance. I'm not looking for anything too extreme, just some simple upgrades that will enhance the driving experience.

First, make sure to upgrade the air intake and exhaust system. This will improve airflow and increase horsepower.

Invest in a performance chip or ECU tune. This will optimize the engine's performance and can provide a noticeable increase in power.

Consider upgrading the suspension and adding a strut tower brace. This will improve handling and responsiveness, making for a more enjoyable drive.

Add lightweight wheels and tires for improved acceleration and handling.

Upgrade the braking system with performance rotors and brake pads. This will improve stopping power and reduce brake fade during spirited driving.
