How can I improve the aerodynamics of a BMW M3?

I have a BMW M3 and I want to improve its aerodynamics for better performance on the track. What modifications can I make to achieve this? Are there any specific parts or techniques that I should consider?

The best way to improve the aerodynamics of your BMW M3 is by adding a front splitter and a rear wing. These will create downforce and improve stability at high speeds. You can also consider adding a carbon fiber hood or roof to reduce weight and improve airflow.
