How to improve handling in a Toyota GR86?

I just bought a Toyota GR86 and I feel like the handling could be better. What can I do to improve it?

You can start by upgrading the suspension with coilovers or sway bars. Also consider getting stickier tires for better grip.

Decrease the car's weight by removing unnecessary items and installing lightweight parts such as a carbon fiber hood.

Adding a rear spoiler or diffuser can add more downforce and improve traction at high speeds.
