Why are you puting money into this car is the first question????

I have to say I have not read the whole thread but from the first few posts I can tell you that you are looking at waisting a ton of cash.

Option 1 on your wish list is fine. I would go with the 16's and run the Falken RT615s in the 205/40/16 size.
Option 2 is a waist of money at like $200 bucks its going to make that much of a difference on the street or the track.
Option 3. VERY important part for the eg chassis!!!! get one
Option 4,& 5 dont bother with. if you want to just give money away I'm a great charity.
Option 5 get ther rear only!!!!

Derek is right get a roll bar if you are gong to track the car. Do not get harnesses unless you will be tracking the car (Autox is not taking the car to the track). The chassis will be stiffened and the car will be much safer with a bar than some JDM braces.

If you do plan on tracking you car do all of you needed maintance first.
1 if the master cylnder, calipers, rotors, lines and pads have not been replaced in the last 4-5 years get a new ones.
2 replace you suspension bushings!!! OEM or aftermarket.... Anyone who puts money into a cars suspension over 8-10 years old with out replacing your bushings just built a death trap.
3 make sure all bolts on the car are torqued to spec... dont ask!!!!
4 change ALL of your fluids!!!!
5 have fun and be safe


Now if this is just for show do what ever you want but if you are thinking strongly about doing more with the car do it right the first time. Nothing hurts worse than having to pay for something twice.

It's Just My Oppinion and my shitty spelling but I hope it helps
