How can I improve my Toyota GR86's handling performance?

I recently purchased a Toyota GR86 and I'm looking to enhance its handling performance. How can I achieve this without voiding the warranty?

One way to improve handling performance without voiding the warranty is to upgrade the suspension system. This can include adding a coilover kit, sway bars, and strut tower braces.

You can also look into getting a limited slip differential to improve traction and handling.

Another option is to invest in performance tires that are designed for better handling and grip on the road.
