So I watched some youtube videos of installing the wheel spacers and decide to make some difference!!! 
Put some wheel spacers on my Toyota Vellfire, make them super flush.
The wheels and the body, look perfect.
Here's the result.
only 8mm on both of the front and rear sides.
those wheel spacers are damn light as a feather (joking)
yes, I bought the same wheel spacers as the youtuber use, but after my hard-working, I heard from my friends saying that wheel spacers aren't safe, so I did some research on this topic, which makes me more confused.
Can anybody tell me?

 

Hi, I'm looking add some wheel spacers too - is this the right size? 5x114,3 / 60,1mm

yes your on the right lines. you need hub centric spacers so there is a lip for the wheel to centre on. for the oem 18" wheels on the 20 series i have went for 20mm rear and 15mm front. could possibly go wider but at this width there wont be many stone chips up the side of the wagon. those bonos spacers are filmsy looking and not sure if they have passed any safety tests. I would go for H&R or Eibach, you get what you pay for...

 

Make sure you tell your Insurance company about the modifications !
