I did find some front air dams from searching, however alot of them are straight fiberglass.

Im looking for something that is more of an FRP (able to take some punishment) and is not ridiculously priced (300+ shipped)

Anyone know of any?

 

Some of the air dams produced back when these cars were new, like the dealer option IMSA air dam, or the air dam made by Kamei were made out of the same plastic/rubbery material that the stock bumpers are. Most of the reproductions made are fiberglass, and there aren't many of those either.
Unfortunatly when it comes to air dams you might want to just take what you can find...

 

word, buy fibreglass and learn how to glass!

 

is there a thread out there on how to install these and make it look right? ive seen a few and they dont look attached correctly.

 

My car will be LOOWWWW so i dont feel like constantly glassing the damn thing

I can glass just fine btw
