What are the best modifications for my Nissan 370Z?

I'm looking to enhance the performance and appearance of my 370Z. Any recommendations for modifications that will give me the biggest bang for my buck?

Adding a cold air intake and exhaust system can greatly improve the horsepower and torque of your 370Z. Consider upgrading to a high-flow air filter and larger diameter exhaust pipes for maximum performance.

Upgrading to coilover suspension can greatly improve the handling and cornering abilities of your 370Z. Look for a set that offers adjustable height and damping for a customizable ride.
