Is my front undertray too long?
Is it? Do you think it will trap too much of the under-hood heat? My first test drive with it on showed no overheating problems...
Here are some pictures, I do not pretend to believe it is pretty. I should have made one in cardboard first and then attempted with the ABS but oh well. I know it's ugly, I know it's not symmetrical, etc. etc.

Mounted: front view
Mounted: rear view

Looks pretty good. Better than spending big bucks for someone to make one for you. And honestly, how often are you gonna see it anyway?
One suggestion (something I plan to try) is to use some sort of 1/4 turn fasteners to facilitate removal for maintenance access.

Ok, I will try to answer everyones questions.
First of all it's 1/8" thick ABS plastic. I bought a 4' X 8' sheet of it from a local plastics supplier, I think it was about $55 total. I still have quite a bit left over, a 4' X 6' sheet would have been enough. Check the yellow pages for a plastics supplier near you, they should have ABS sheet in various thicknesses.
I'm not sure what rleete means by 1/4 turn fasteners. I do need a better way to fasten the undertray to the front lip. As of right now it's kind of a pain in the butt to take off and reattach.
I know the undertray will help cooling. The whole reason I built it was to help cooling and hopefully increase front downforce. Having an undertray reduces the amount of air that goes under the nose of the car and forces more air to go through the radiator (increases pressure in front of the radiator). My fear was that the tray was too long and would possibly block some of the airflow out of the engine bay. I had read that if the undertray is too long it can cause problems.
Sam: I have a PLX M300 wideband not a LC-1. I have the controller smushed between the center console and passenger seat...
Thanks to everyone for the compliments. I don't think it's pretty but I sure hope it's functional.
