Which is best to lift Yaris??

[Abdoo]

Hey there everyone,

This is my first post on this great forum, so please bear with me, I have a 2008 Yaris (Gulf).

I live in Yemen where roads are not very well done, broken and the bumps are huge which may cause the bottom of my yaris to scrape if I am carrying four people in my car...

I've heard of lift up kits, but unfortunately they do not provide them here in Yemen, however what we have are are I think are spacers but they come in either aluminum or rubber I have attached two pictures showing them...

My tire size is 185/65/15 as seen below..

My question is which would be better the aluminum or the rubber? Because I am getting biased opinions from mechanics..

On a side note someone advised me to get the rear coils of the corolla 2007 and place them on my yaris which will give it a lift up what do you guys think?
