From celica to yaris questions!

[crkdutch]

I currently own a 2000 celica gt.
Going to sell it.
First post btw!

I saw a slammed yaris on the internet and its been in my mind ever since.
Strongly considering into buying one. Im thinking of getting either
a black or white one. I would buy a manual one. I would only use it for summer driving so I will slam it. It would be a 2 door of course. I'd buy a used one probably between 05-10

What I want to know:

- Is the sport trim worth buying? Is there really a difference between a RS and regular one?
- Are there any defaults with certain years or do certain years look better aesthetically that i should be aware of?
- Which in your opinion is the best rim size and offset, tire size, coilover spring rates, inches of drop for a flush fitment?
