^ That's a few grand right there, but solid list of start out mods.
Up from there:
- Coilovers if you want to track, go-cart like handling at the sacrifice of comfort.
- Upgraded Brake Pads, Braided Lines, Eg: Project Mu HC800+, subjective and argumentative topic.
- Upgraded Rubber, Everyone here likes AD08R's as the most effective, and probably most expensive street/track tyre out there.
- Include the End-Links with the Sway Bars
Moving forward from there,
It's basically,
- Turbo
- Injectors
- Fuel Type
- Fuel Pump
- Retune, / Aftermarket
ECU
And generally becomes more complicated depending on what you're after with the car. Keeping in mind, if it's a daily driver, there is a line in the sand where it becomes not that.
