I dont know what to look for,,,,,,I know the one im thinking of in my head isnt there on my car.
some one help please????
Does any of you recomend one or the other or both or none,,,,I have a Iroc (w/out ram air hooked up) that I lowered on the front alot. My cars been motested a little before i got it so im thinking the deflectors are gone.

 

I would be interested in some pics as well.

 

heres a pic i pulled off of a gta... i dont have the side ones... i didnt need them

 

well unfortunately i cant tell you which parts those are...but i CAN tell you that the deflectors etc. under the car make ours cars run MUCH cooler. when i got my car it ran WAY too hot...so i went and replaced the one that sticks far down and the one that curves back from the front ground effet to the front of the radiator....and it ran perfect after that.

not sure if these are the pieces you are looking for, but these pieces do work very well in cooling the car down.
