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 15mm on the front.
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?

 

Wheel spacers are perfectly safe is made to a high quality, if correctly fitted to the vehicle, if used in moderation.

Basically don't cheap out or the studs may break.
Make sure they fit your hubs/rims correctly as vehicle wheels are hub centric.
Don't stack five four inch wheel spacers on each wheel.
