Want to get XT-006 wheels but want to know how they run

[Riolizares]

There’s these wheels from cosmis racing called the xt-006 that I want and literally every other wheel I just don’t see on the car besides these. But the only problem is that it’s +8 +10 or +30 for the offset. I believe 8 and 10 is just to aggressive and I would go with like a 20 but they don’t have that offset in these wheels. I know how offset and all that works and I like the look of that deep concave look I just don’t know how they would fit on the car, yes I’m stock ride height and looking to go to coil overs. If anyone can help me with info on these wheels that would be a blessing.
