hey , i need help looking for an aftermarket rear underbody wind diffuser for a 2003 G35 coupe, so far i have found noting, it would be much appreciated if you can send me links or give me where abouts of them.

thanks

 

nismo is what I have

 

ya but the fins are too short , i need them like 3 inches more , not saying its ugly or nething , i liek it still but i want the fins bigger

 

hey man i was thinking the same thing so here's what i did. i went to google and typed in top secret diffuser and, yep they make one although its a bit pricey like 1200 but its all carbon fiber and you can also get the vortex generators. It looked pretty bad, but if that phrase on google doesnt work keep tryin other variations.
