you can fit any rim to these cares but as ling as the rim is light it's fine. the ones on your car are MUCH heavier than they should be. I've seen these in the markets and trust me, they will affect economy, handling, ride etc.
as i said earlier, go for anything which is lighter,... it's not about fashion, it's about function. the original vitz/yaris alloy looks like this
however if you are happy with the ones on your car then don't change them.
