I would go for wheels that are painted all over. I had my whole wheel powder coated as they were half paint half alloy that was just clear lackerd.
When the part of the alloy that is left just alloy and lackerd gets chiped the wheels start to look a mess.
The wheels on the picture shown on the link you put up have silver rim and are all painted black once you chip the edge of them the water will get under the lacker and just bubble it they will look a mess then.
I had my alloy wheels 2 weeks and noticed were the nuts went in that there were bubbles in the lacker. I must have scratched them when putting the nuts in while putting the wheels on and in that time the lacker was already bubbling and they were starting to look a mess.
That is the reason I had them stripped and powder caoted.
Oh my wheels are also 17" as I was told you have to add a steering rack limiter and also get you speedo re calabrated if you fit 18" that was to much hassle 17" dont look as nice as 18" but they do for me.
