How do I improve the handling of my Nissan GT-R on the track?

I have been struggling with my Nissan GT-R's handling when I take it out on the racetrack. It seems to have a lot of understeer and I can't seem to find the right balance. What can I do to improve its handling and become faster on the track?

Firstly, make sure your tires are properly inflated. This is crucial for maintaining good grip on the track. Secondly, consider upgrading to performance tires specifically designed for track use.
