I think if you put a larger splitter on the front you'll get higher air pressure in front of the car to some degree, which will push the air down through the cooler. So now I plan on covering the cooler but leaving a gap at the end of the splitter for the air to evacuate, and the splitter might even help with airflow or at least not impeded it too much. If the trans cooler needs more air, there's a slot in the BMW splitter in the vid that looks like an excellent design. OTOH, I don't love AJ's Camaro splitter ventilation as much, the holes seem like a suboptimal solution, but he can leave them out. Those holes are going to significantly reduce how effective the splitter is... The AJ Splitter has a foam core and airfoil profile so replacing it with plywood will be MUCH less effective unless you work on shaping the plywood similar to the AJ splitter, which is possible given the right tools. I also just checked out a Zebulon splitter on a car at Time Trials this weekend and it's quite thick for a splitter, maybe a little thicker than the AJ, and the underside is fully shaped. Looks great but also expensive. AJ's splitter would be less expensive but still not cheap, and neither are quick release.

Some good points.
1) I forgot about the profile shape of AJ's, which would be unlikely to get with plywood. Perhaps pricing a replacement CF board from him is the right move; I think it's a matter of "when" and not "if" the boards get damaged between track and trailer.
2) Also, as you noted, I wonder if leaving the trans cooler hole completely off is the right move for manual transmissions?
3) I also noted that there are no diffuser tunnels on the AJ board. I wonder if unnecessary or not practical, given the mounting points or other obstructions . . .
