aftermarket undertray's (bellypan)
Anyone know of an aftermarket undertray (bellypan). I've been looking for a while now and I have one I've made myself but I'm not too keen on my own craftsmanship. Thanks

honestly aluminum/sheet steel or some sort or plastic would be ideal, keep it cheap and durable. If anyone ends up making these or at least makes some sort of template let me know. I'm sure there is a lot of interest out there.

I have been pondering going to lowes/home depot and making one out of sheet aluminum, and adding an underbelly diffuser maybe, but it has been just a thought so far.
I daily drive my FC since I sold my Camry, so I haven't had time to pull the tray off and get anything going.

FC guys are too cheap to buy anything legit and plus folks run a variety of front ends. The combination of a diffuse AND frugal market means no-one's stepping up to make anything.
It's pretty much DIY or nothing.

I don't think its about us being cheap as much as no one really caring about the advantages of the under tray. People spend money on body kits and wheels all the time, no one cares about having a cleaner engine bay or less aerodynamic drag.
I personally would buy a replacement if available. Mine has several cracks and is held together by duct tape in one place.
Not true at all. It does help cooling to the radiator but your car will NEVER overheat without it if all other parts of the cooling system are operating properly. I ran without one for over 3 years, 2 of those NA and one 6 port turbo. I've driven the **** out of the car redlining third and fourth and never had a cooling problem.

But just after I rebuilt my NA engine, I forgot to put the pan back on and left it idling in the driveway for some break in and found my temp needle had risen to about 2/3 up. Now this may not be "overheated" but it was definitely way too hot for sitting at an idle.
I would conclude that at higher speeds, the pan isn't going to make too much of a difference, but if daily driving around town, it's going to cause problems.
Well if you're driving fast enough, sure it's not going to overheat. Redlining third and fourth I would consider to be fast enough.

When your idling the undertray really isnt doing much of anything IMO. The undertray is there to direct air towards the rad while in motion. I have had no undertray for quite some time. S4 N/A with electric temp gauge tee into the BAC coolant hose. NEVER higher than 185.
I just put a bomex rear bumper on and also loving my new exhaust setup.
