I found this spoiler on Egay. Appears to be made in the USA. Looks great. I assume installation is with double sided tape.

Would look even worse on a non-wide body G...doesn't flow with stock lines at all

 

Hmm, I would just have to see it but its a bitt tall for my taste

 

you HAVE to have aggressive styling to pull this off. If not, leave it alone. IMHO.

 

1. Are you slammed?
2. Are you wide body?
3. Do you have excessive tire poke?
4. Are your fenders rolled?
5. Are you interested in EXTREME downforce and +5hp stickers?

If you answered yes to to 2 of these 5 questions then this spoiler is for YOU!

 

Oem would look better imo

 

Way to big for my taste... I'd pass on it

 

lol^^^ except you would need the +10hp stickers for it to look legit
