What is the best modification for my Nissan 370Z?

I recently purchased a Nissan 370Z and I want to make some modifications to improve its performance. So far, I have replaced the exhaust and added a cold air intake, but I want to do even more. What modifications do you recommend for the best performance gains?

Based on my experience with the Nissan 370Z, I would highly recommend upgrading your suspension. This will greatly improve the handling and cornering capabilities of your car. Additionally, you may want to consider adding a performance chip to increase horsepower and torque.

Don't forget about the brakes! Upgrading to a big brake kit will not only improve the stopping power of your Nissan 370Z, but it will also reduce brake fade during high performance driving.
