yeah that looks great, is that made by carl faussett, I see it doesnt fit s4 or gts...but looks like it will work
!!!!!!!!!!!!!!!

 

I am not sure, although they had a few other 928 specific pieces as well.....Anyway, I was thinking of using that as a base to build a "Strosek" type spoiler for myself, when i found that trolling on Ebay. It looks to be substantial and claims to add no stress to the existing OB spoiler. I would have to see the front to verify it, but I am with you on it fitting the S4.......just might have to move some mounting points around.

 

That isn't one of ours, sorry.
