Secondly, get some great tires when you can. Once you have those tires, if you are interested, get some driving time at an autox or HPDE.

Then, if the mod bug is with you, think about your end goal. Do you plan on going FI at some point? If so, then start with the exhaust (70mm is a good size for FI). Then think about the pieces you will need for FI and start working on gathering those. Check out the FI subforum to find out what that is.

If you are not going FI, then think about what you want from the car. You can do the aesthetic mods and you can do the traditional bolt on mods. Just realize that bolts on will not give you a great amout of power or torque. Most of them will only give you 3-5hp (if that) but they will change the sound and feel of the car.

Here is my recommendation:
Full vehicle maintenance
Tires
Exhaust (70mm)
Test Pipe (70mm)
Intake (if not going FI)
Audio system
Aero upgrades (front lip, splitter, side splitters, rear diffuser, rear spoiler/wing)
Suspension upgrades
Braking upgrades
Forced Induction

Good luck and have fun!
