Another reason is I didn't want to install the triangles behind the stock firewall that would get in the way of the standoff mounting bolts that have large metal washers on them. The washers fit flat against the firewall. Another reason is I didn't want to negate one of the benefits of the engine design, anti vibration casing. You will notice that the standoffs for the EME engines are designed with a large mount to firewall footprint. Installing washers increase the length of the standoffs thereby increasing the vibration factor. I don't know about how much, but for me forgoing all the above in engineering wasn't worth not extending and thickening the firewall. It really wasn't that big of a deal considering the firewall just comes out of the box so you can trace around a piece of plywood, then done. Sandwich them together and you have a good reinforced mounting firewall that doesn't need the triangles in the rear. That's my story and I am stickin to it.
