Anyone know what the three thickness options are?

 

They said:
.063
.09
.125

They may do 3/16" if there is enough demand.

 

Would be nice for winter to protect from ice blocks and chunks of dislodged pavement or for those that rallyX, but it removes all the air inlets that cool the transfer case and turbo area. Those little slots aren't going to compensate for the stock inlets that direct flow up toward that area. I would be hesitant to run this in warm weather without at least some form of aftermarket temperature monitor for the transfer case.

 

+ aluminum is highly heat reflective, great at keeping heat out but also keeping it in. You'll be further hotboxing to a degree the heat coming from the car, esp. when not moving.

 

i got the off road option. ill see how the transmission temps are in warm socal. i might bring the oem tray at the track...

 

I've considered adding my own ducting with screens to these for my car. I'm staying stock height, but road debris in a couple places I go can make things interesting. I'd like to duct it for the transfer case and turbo, also considering modifying a stock hood with better ventilation. Also a little concerned about having these on the car without proper ducting and having any warranty issues. They could blame all sorts of issues on heat due to changes in airflow.

 

personally im not happy with my tbw, they are going to offer a $40 duct tho. at least its easy to take on and off. so i'll only use it when im hoon or rallycrossing. for daily it heat soaks too much. and definitely will not run with it on track. the rivnuts are needed for the offroad option as the bends dont hug the subframe so you it needs to be tighten by a bolt and bend as needed.
