Thanks first. Sounds to me that

Sahara is the same as X except some facial makeup.

Rubicon has real mechanical difference from X

X can be upgraded with JK project and be almost as
capable as Rubicon

Is my assumption right?

More questions;

Did you do your project JK alone or sent your Wrangler
to a bodyshop?
If you changed wheel with different size, did you also adjust the speedometer and odometer setting?
Does it need to be approved by some goverment agency?
