Full disclosure guys, my MCR splitter/diffuser came in Friday, and JimA and I were able to take closer look at it on Saturday as we loaded up my car to take it in to receive its new motor and all of the go-fast parts listed up above.
The MCR is a complete disappointment to me. Being a "drop-in replacement" for the OEM couldn't be further from the truth. It amounts to a single-piece fiberglass bottom tray that replaces *part* of the OEM splitter and a lip that has holes in front for air to come in. The bottom tray has some ducts riveted on them, not unlike what Ourtoy did. The molded pieces don't even sit flush with the fiberglass, so air can escape into the void above the tray. The ducts themselves form a weird air pattern that doesn't really seem to direct air, in any organized fashion anyway, towards the brake rotors.
But the biggest rub is that, because it's really not the complete splitter/diffuser, we'll have to hack up the OEM splitter in order to re-use the "frame" because that's where the structure and reinforcement comes from, as well as a place for the MCR lip to line up with the ducts.
I've e-mailed Bulletproof with my concerns, but haven't heard back. They are usually very busy but eventually respond. I'm not sure whether there's anything they can do, since this was custom ordered in September and had to be flown as checked baggage from Japan at significant cost.
