Does anybody know where i can buy just the lower air diffuser found on the gt500?

 

I think its part of the bumper.

 

Yeah, you have to buy the whole rear bumper.

 

apr makes a carbon fiber diffuser that works with the stock gt bumper that would look killer, as far as I know you have to buy the bumper but if you want that look its cheaper to order the ford accesories rear bumper for the cs/shelby gt and its the same bumper
