I know the Kiwami isn't available in this size, but my wheels are 17x8 +42 fitted on stock tyres. They do stretch a little, but nothing too silly. Having said that, 8" wide rims would be the max you should go if using stock tyres. Anything more and you need to go 235.
Between the choices you have (for using with stock tyres), here are my opinions:
1) 17x7 +38: Second choice. Pushes wheels outwards by 10mm
2) 17x7 +47: Stock appearance. Does nothing to fill wheel arch.
3) 17x7 +53: Avoid. Retracts wheels inwards by 5mm.
4) 17x8 +35: Pushes wheels outwards by 26mm. Might be too much?
5) 17x8 +47: First choice. Pushes wheels outwards by 14mm.
6) 17x9 (any offset): Out of question if using stock tyres.
I've purchased wheels from
www.jdmconcept.com.au and would recommend them. Getting your stock wheels power coated properly isn't exactly cheap and you're not doing anything to fill up the wheel arches. Perhaps you could get some plastidip and spray your factory wheels first to see whether you like it. If you don't, at least you can just peel the colour off.
