I actually prefer
NOT to have it
That way, I can tint the windows to my liking
With rear only tint, you have a choice to either match the front with aftermarket tint or tint and get mixed matched windows
Like with my FZJ80, it originally had rear bronze tint, but I had the whole thing done limo tint (5%)
From the outside, the front windows look darker, but are easier to see through...
The rear windows look lighter, but are harder to see through....
This is due to the polarizing of the factory tint...
On the other hand, from the inside, it's much easier to see through the rear double tint than the front single tint
