My answer would be why?
I mean sure it's cool and you will stand out and your ar will be really nice, but 10k is a lot to spend on something that you will never get your money back from.
I mean, i'm not saying spending / modding is bad, but i'm saying 4k tops would be enough i guess. But if that is what you want then go for it!
Summary:
CAI / Air filter - $400
Exhaust - $800
Extractors - ~$800
Rims - $1500 cheap, 3000+ nice ones
Veilside Bodykit: 1300 unpainted, 1900 painted (cheapest bodykit)
ICE - 1000 to infinity
The list can go on goes on.
One this that you have to ask is what you want the car for, show? look factor? a bit of everything? track work? drags?
My car is setup mostly for track work, with a bit of bling attached for the slightly look at me factor.
