I cut mine using a utility knife and then sanded down the rough edges using some 800 grit sandpaper. Turned out pretty good!
When I took my Jeep to Safelite for a windshield repair, one of the guys was telling his buddy about how the t-Rex /is/ standard (I added it to mine) and how you have to pay extra for the OEM windshield in order to get it if your windshield is replaced. I tried to explain to the guy that it was just a sticker and he doubled-down on it coming that way from the factory. I just nodded and smiled.It should be standard along with the Jeep.
I don't have any pictures of the process but here is what it looks like after cutting itI should do the same... Do you have any pictures?
I have a similar setup on my JLUR and i get 15mpg. i do not baby it.
this is when I was driving normal before I started babying it... now I managed to get it up to 14.
I do a lot of city driving, and the freeway I do go on has a ton of traffic. I have a 104lbs wheel combination, but I can't say the fuel mileage was much different before... I am trying to accelerate slow, stay under 70.. roll to lights.. nothing is helping..
Just trim the parts you removed and replace the part behind the bumper. That is what I did. All wiring is still protected.
