Don't forget about your brake fluid too. My first track day in the F30 was on the stock fluid and my pedal was getting squishy late in the day.
I've used Motul RBF600 on my last few cars with great results, only downside is you really should swap it out every year. Plus amazon has it for $16 a bottle on prime. The Porsche crowd also swears by Castrol SRF fluid. But it's a bit pricey in comparison.
