What should I consider when upgrading my BMW M2's suspension?

I'm looking to improve the handling and performance of my BMW M2 by upgrading the suspension. What factors should I take into account before making a decision? Are there any specific components or brands that I should be aware of? Any advice is appreciated.

First of all, you should evaluate the intended use of your M2. Are you mainly using it for daily driving or do you plan on taking it to the track? This will help determine the type of suspension setup that would best suit your needs.
