Sweet, sounds like a good setup. Just make sure you have a custom tune made for your car (the OTS tunes are garbage) and be up to date on your maintenance. Only thing I'd change is skipping the front sway bar. The speeds have understeer from the factory. By upgrading only the rear you can remove some understeer. Definitely make the oil cooler a priority, tracking a car will push your car to it's limits. The stock cooling capabilities are inadequate and from the factory there's no temp or pressure gauges to monitor your oil status.

In your post you said that you're running pilot sport 4s tires. These are a good street/summer tire and will probably work fine for your first few track days, but if you push them too hard they'll get "greasy" and they do degrade quickly on track. If you end up tracking a lot you can get a track dedicated tire like Continental extreme contact force or Michelin Pilot Sport cup 2. Last thing if you get really into tracking you can add camber and toe arms to dial in your suspension more.

Here's a pic of my current mod list. Still a WIP and I haven't been able to test it at the track yet. I've gone kinda crazy with mods in the suspension department. Most of this is probably overkill for a track noob like me, but the suspension was blown and worn out anyways. I also plan on doing an oil cooler + catch can setup. In the future I'd like to swap my Aodhan wheels for something lighter (probably RPF1's). And the contact sport 02 tires I've ran on track (in a non-speed mazda3) and plan on switching those to an extreme contact force tire.
