I was just taking mine off the other day. It's not 20 screws, there's only 10-12 hex bolts.

What does the one you have look like? There's plenty of cheaper aftermarket ones from Japan that are made from fibreglass rather than the factory plastic made ones.

Oh yeah, I know of one car that had theirs nicked at the docks. It's piss easy to take off and you dont need a jack at all. They only took the front section and not the mid piece.

Mine is plastic, the only pic I have is of the back piece to it, the part that faces the chassis,

it looks like this.. the front piece looks more simple, just a big flat sheet of plastic..

Honestly I'm totally confused at this point, the workshop was trying to tell me one of the

diffusers looked like an "old" design not expected to be the one on the car. I am not not

sure whether they were talking about the carbon rear one, or the front piece or this piece!

paranoia on my part probably. But if they shop didn't bother raising it as an issue, I wouldn't

be freaking out.

The piece you have there is the mid part, right side is to front of the car and left to the centre. If your front diffuser is plastic, i'd bet my dollar is the factory one. Perhaps they are talking about the rear carbon diffuser. If they did rip it off, it's going to be damn exp to replace.

Also when you say simple, it does look pretty straight forward to me as well. I think you should check out the car itself.

I may have taken a photo of the diffuser before I installed it on the car. I will look when I get home and try to post it.

The engine cover, pictured in the last 1-2 posts, has two holes in the right side that hooks from the original diffuser fit nicely into, and I'm pretty sure you've got 12 M6 bolts that hold it on, all spaced around the front.

The original one also has two pieces of triangular foam on it, similar to the four pieces shown on the engine cover. Often, these are ripped off, but I've never seen the foam pieces on a non-genuine diffuser.

Incidentally, the 'lip' on the car itself is much smaller and is standard on all the GTR (with two holes on the left and two on the right), but the full underbody diffuser is only part of a V-Spec or II package. It looks like a flat piece but creates a central gap that appears to be divided into three sections when it's mated up to the lip. The non V-Spec literally looks like it's missing a part, but really isn't.
