DC5 Rims & Tires

Hi, just curious about some more detailed info and people experience with fitting rims on dc5. im looking into getting an aftermarket set and want to go 18's but not sure if they would fit alright.
i have king springs in, and also not sure if i need my guards rolled.
The sizes like:
18×9 +33mm 5×114.3
18X9.5 +10MM 5X114.3
18X9.5 +34mm 5X114.3
Also with best tire sizes to go with any of these sizes.
really don't want to stay at 17"s as already have a set.

Rims in mind are:
Vordoven Forme 9
Cosmis racing XT-206R
Advan gt
Work emotion CR2P
Work emotion D9R

Also if you have ordered from US, how long roughly did you wait for posting. Or is there somewhere within Australia (Sydney) i could maybe order though or look at. Pref JDM Style, cheers CNiX
