That makes a big improvement in my opinion.
Show us a side or angle view of the wheels with the spacers installed.
Where did you get them?
I did something similar. I had custom spacers made that were also wheel adapters. They have the Fiat bolt pattern and hub centric bore on one side, the extra width I wanted in the middle, and a different bolt pattern and center bore on the outside - to match some wheels I want to use. Also has the studs installed like yours. Plus some bolts with decreased thickness heads to mount the thinner spacers to the hubs, without interfering with the wheels.
