air scoops and skid plates

I Would like to see more pics of this , I'd like to make some similar items myself , i have a torch and I'm sure i can get the lexan local , How much did yours cost per sheet If you don't mind me asking Borednstreched ?
 
i had bought a sheet for a drag windshield for my 91 tsi awd. it was 80inx80in it was $140. i used the leftover. you could get away with a 50x50 sheet to do all the skids and 2 scoops.
i ended up changing the shape of my scoops to catch more air.
