nice choice m8 looks really good
but you know why you feel the rim looks small ? due to the chrome lip
those rims always look a tad smaller .. rims with a flat spoke that runs into the outer edge always look a bit bigger..
sure 18" would have looked great but i feel this def looks great as well
and when you lower it it will be more balanced all together
on my ignis i went for rims with a lip on purpose , sure mine are in one color but i do have a small / narrow lip
and because of that the spokes / center , are / is smaller .. because i saw other cars with flat spokes wheels and they looked way to big on such a small car , mine imo now look almost like 16" on pictures
your car is quite bog and also a station witch also looks bulkyer so that combo makes them look smaller then 17" but still i say its def not too small imo
and if you ever get new wheels (whitch would be stupid because you now have these
)
i would say 18" with not to much lip ....
