How do I maintain the top speed of my BMW Z4?

My BMW Z4 seems to struggle at reaching its top speed. What could be causing this and what can I do to maintain the top speed of my car?

First, make sure your tires are properly inflated and in good condition. This can greatly affect your car's top speed. Additionally, check your air filter and fuel filter to ensure they are clean and free from any buildup that could be hindering your engine's performance.

Another common issue that can affect your BMW Z4's top speed is a clogged or worn out catalytic converter. This can restrict the flow of exhaust and decrease your car's power. Consider having this checked and replaced if needed.
