Mine is tied into the roll cage. You can see where the DOM tubing in penetrating the firewall and then tied into the interior cage. In fact the cage goes from front bumper to rear bumper. I also incorporated a removable engine cage along with a removable radiator top support. This way if I want I can remove the radiator and do not have to raise the engine up other then an inch or two and then pull straight out.
Here you can see how it's tied into the front bumper.
Then junked anything plastic and made my own steel grill. Added round Hella lights. Only reason they're round is because they used to be mounted on the roof. Did not use them to look like a jeep or EB. Rather had rectangular ones to keep the looks of a B2.
This is all I got for inner fenders lol. All this work was done before it went all Black.
Now that I've gone 40" IROKs there is going to be some major work on the rear wheelwells. Fronts fine.
The other benefit is the hood is completly removable with the pull of two pins.
Then remove the removable fenders and talk about trail visibility. I can look right thru the engine compartment for a good line to run.
With removable fenders removed, the exo acts like fenders, well almost.
