hey everyone, new to celicas Options

[mitchy]

hi everyone i found this site from Ozcelica and thought i shud sign up as theres lots of info and stuff on here.
I'm from australia and I'm 16 and get my license in 2 months. I saved up for my celica and bought it myself, a 1997 ST204 SX liftback. theres some picures on here i dont know hpw to show them here but yeh. anyways it goes pretty good i donmt really know much about theM. I have a fgew questions though:

1. Whats the cosmetic differences between ST204 and ST202 and all the others? like can bumpers and what not fit each other?

2. how wide rims caan you go before they scrub on full lock?

3. i have a TVSS security system which the local toyota dealer tells me mite be a "dealer/port fit", on Ozcelica someone said the box would be under the passenger seat (which its not, that would be too easy) just wondering where that is.

4. do those tweeters in the door actually do anything?

thanks, i hope to learn things from the people on here
