Buying a good helmet is the first thing I always suggest. No point in go-fast mods if you hurt yourself on a mistake (which will happen eventually). Eventually if you find you take to the sport, then a good seat does wonders to any track car, as well as a harness. A good seat and harness that keeps you planted has been proven to help lap times.

Next I'd go with tires. Everything everyone does to their cars performance wise, means nothing if you have bad tires. No matter how fast you are, how big your brake kit is, how expensive your coils are, it all comes down to those 4 points of contact. So make sure you don't cheap out, and buy good, new tires.

Lastly, I would get an oil cooler. I would suggest a 34 row with a thermostatic plate. No point in going smaller as long as you use the thermo plate. The oil in our Zs run very hot on track days, whether it's cold or hot, so unless you want to "embarrass" yourself hitting limp mode mid track session and having to let it cool off for 15 minutes or so till it's good to go again, I'd get one.

Other than that, I hope you take to the sport and make sure you post up the results from your first race. Good luck. Also, it never hurts to message a motor sports team with a 370Z. Most of the time, they have no problems answering any questions.
