What are the must-have features in a Ford Focus for maximum performance on the track?

I am planning on purchasing a Ford Focus to use as a track car. What specific features should I look for to enhance its performance on the track?

One feature to look for is a limited-slip differential, which will greatly improve traction and handling on the track. Also, consider investing in upgraded brakes for better stopping power.

Upgrading the suspension and adding a performance chip can also greatly improve the handling and power of your Ford Focus on the track.
