I did cut out the three little supports by the latch but in hindsight, it's not necessary to fit the evo intercooler. I was referring to the support beam inside the bumper itself. It does compromise the safety of the car as you're taking out a major piece of the front impact zone. Anyone with a welder and more time could leave it partially intact while still having enough room. The end parts of the support (that bolt to the car itself, bolts for the bumper are behind the marker lights btw) are still there on my car. On the picture, the red bar is where the bumper support is inside the bumper cover, the blue part is what you have to cut out to fit any kind of a large intercooler.
**In my opinion**, in any kind of major crash in this small of a car combined with the speeds we take them to (who else is a member of the 150 club), that little piece of bumper isn't going to matter in the end run. If you run into a lot of things with the front of your car, don't do this.
This is also my way that I did it, I'm not recommending anyone doing it the same way, I'm presenting it as another option. I take no responsibility for anyone that hacks out their bumper and then promptly runs headon into a tree.
