True, the fact is that the area you are talking about (bellhousing\catalyzer) is the most troublesome one, flow wise. Going back from there with 2 panels that sit "flush" to the exhaust will work as good as a single panel.
Our transmission really gets too hot, my gauge says so!

I am worrying about the heat, I can make modifications later when i actually do swap. I have already made modifications to 2 of the panels for increased cooling effects and increased air flow around the high temp components

Finished the section that goes under the diff, the exhaust has an opening to cool it slightly and i need to just add some secondary vents to help cool the diff under high load.

I plan on putting some large ducts in, the sides for the suspension travel are very open so that should help right? Again im not an expert at this just trying something nobody else has for our car

Air in doesn't do much good unless you can get it out. If you don't have a direct path out, it will become stagnant/turbulent and now you have an oven. The biggest problem is that exhaust pipe baking the diff. Heat wrap or heat shield and some louvers are cheaper then a diff rebuild.

I know Sifu is getting his car ready for some track time since he told me he talked to TeamRX8. I am sure the diffuser/his 19 inch wheels isn't going to be on when he does take the car out of course.
Plus Rotr8 pretty much made his rear diffuser up from scratch. It's nice to see owners go outside the box like the two of them did.

I hope y'all figure out everything and make it work right!
I see that we have a lot of clearance issues in my opinion since I have a carbing bar right under my Mazdaspeed exhaust. Those combined are already low -__-

We actually have a lot of space, all you have to do is remove the lower part of the bumper or start from a mazdaspeed rear one.
Since chassis braces do nothing and cause clearance issues the decision between them and better undercar airflow is a no brainer, too.

But the show must go on!
Also, wouldn't allowing air flow both above and below the diffuser be better, as the airflow above will force the diffuser down and create downforce?
