1994' GT styling, Help :D Options

[RaceDVS]

First off, this is my first car, and I am new to these forums. I have a 94 celica GT coupe (at my buddies house bored n all, I'll have pics up a while later).

I am looking for some aesthetic advice and such, the stuff I haven't yet found by searching forums.




Okay... So I am looking to get new wheels. I was wondering if I could fit 18"http://www.1010tires.com/wheel.asp?wheelbrand=Enkei&wheelmodel=EVO6+-+Anthracite onto my car.

And with new wheels I would need new tires. I am interested in tires that are black black black and not very big. I confuse myself when it comes to tires.



Next thing on my list was a body kit, side skirts and all. That 'magic lip' one i think it was called caught my attention.
What kind of work and all does this involve?

and also will any of this affect performance? since I'm also interested in that, like i picked up somewhere that there is an optimal wheel size and such.
