Motorsport Student Help

Hi all,
I am a motorsport student and my task is to produce a technical literature report which focuses on a specific part of a race car. It can be simple or complex. The topic must have a cutting edge technology developed as well as have opposing opinions to the topic.

The example I was given was. Does having a larger front splitter reduce oversteer. (for obvious reasons of cheating I can't use this example).

I am really struggling with trying to come up with a component to research into, and would hugely appreciate any suggestions.
Thank you all.
