Thank you guys!
As for the rims, they are 20's and called ADV 7.0M V.2. from Hobby Design, here it is:

The dish and the outer sleeve are separate parts. What I changed is that I glued the dish to the back of the sleeve not to the front, so this way those bolts are not visible to make it look even a bit bigger.
As for lowering I tried my best that was all. I mean the inner part of the rims sleeve touches the swing arm at this ride height so to get more lowered look I would have had to modify the arms or the rims. Perhaps if I use the rims "normal" way not as described above I would have gain another 1 mm or so, but you guys are right, it would need lowering.
Thank you guys for your comments!
