What are some essential modifications to make to my Toyota GR86 for track racing?

I recently bought a Toyota GR86 and I plan on taking it to the track. What are some essential modifications I should make to improve its performance and handling?

First and foremost, invest in high performance tires for better grip and handling on the track.

Installing a cold air intake and a performance exhaust system can improve engine performance and increase horsepower.

Consider upgrading the suspension with coilovers or sway bars for better handling and cornering.
