k guys i have been looking around the net for a while and still cant find it
what im looking for is a diy extended fender for a honda seen a itr track car today and the stock fenders seemed to be extended out where they meet the door to let air out it looked pretty cool any one know where i could find out how to do this

 

Im betting this was a fiberglass deal here. I had a set that came with my civic when i bought it from Philip Chase. It might not be the same one your talking about though.
I think the manufacturer was based in Massachusetts. Off hand I dont recall their name. You might want to IM him and ask.
