Wow, strike two for me(?)... I was considering the CF spoiler this vendor offers for $210. shipped but after reading this thread in addition to the fitment issues I'm going through with a vendor on this site (http://forums.hybridz.org/showthread.php?t=149348&page=3) for a different CF spoiler, I'm a little gun shy. I can see this panel being a difficult piece to make but spoilers shouldn't be that hard to make and fit right.
I too would like one of these rear panels if they can work out the fitment; please let us know how it goes when/if you get a replacement.
