Just got back from test fitting from GT-Spec. They just released the new carbon fiber rear diffuser from GT-Spec/Blacktop Aero. Fitment is great and looks great on the sedan.

Fits 2007-2009 G35/G37 sedans all sport/non-sport.

Wow, I like this rear valence much better than the Autokits one. Fitment looks great too. Do you know if this is available only in CF or also in FG? More importantly, can you let us know the price?? If you cannot disclose the price, where can I inquire about this? Through Ravspec?

$425.00.... I was about to order the autokits but the gills were too small for me and the vent I didn't like.

Only in CF right now.

Do you know if they plan on any GB for this diffuser?? I am definitely interested..

Looks very nice, but a little pricey

^ Hence the need for a GB.
IMO $380 sounds like a reasonable price

looks sick!

Did they say anthing about matching rear side spats?

I personally think that it looks cleaner without the rear spats. IMO spats compliment the look if you just have just the valence overlays.

looks good

how does it attach?
tape? screws? No drilling involved, right?

Looks good. I talked to Mark the other week about getting one and he was telling me it was still being re-worked. Looks like its finished now. Can't wait to get it. So does it work with the CF Rear Apron?

I think having the rear cf valences will take away from this diffuser. In person it looks much better b/c pics don't show the angles of this piece.

yes, it's 3M tape, and drilled into the bumper. I dont want this thing flying off on the highwayu

Drilling is a big no no for me, I'll go for the autokits one, which reuses a screw/nut behind the plate.

the BlacktopAero reuses the 2 screws behind the plate as well.

I'm referring to the bottom of the bumper where you don't see. There are 5 screw holes that will be unseen since its o nt he bottom, which you'll probably should do with the autokits one as well.
