How do these wheels compare

How do these wheels at discount tire compare to a wheel that 16x8 with 4.5 backspacing? These are 16x8.5 with -6 offset, I'm just trying to compare. I really would like to get the SCS SR8 and I beleive they have 4" backspacing but they are so hard to get. Would these stick out further than a wheel that has 4.5? To me I like a stance wider than 4.5

 

The 16x8.5 ET-6 MB 352 has 4.5-inches of backspace. That being said, the MB 352 will sit exactly the same (towards the outside) as a 16x8 with 4-inches of backspace.
