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.

    • It doesn't look like there's a lot of options out there these days, and what's out there is performance oriented aftermarket stuff (with the GTR markup) I wonder if there are other cars with similar springs, after all its just a matter of length, diameter and stiffness. Alternatively, I did see coil spacers. Probably not the best option, but could be serviceable too.  
    • Final thought for now. Obviously the reason I was in there was to check everything is OK cooling wise, pull out the radiator to flush it etc, but I have to say the factory has done a hell of a lot of thinking about air management in a way they never did back in the R chassis days. The Redsport/400rs have (from engine forward) 2 large shrouded fans - radiator (incl AT cooler) - AC condenser - Intercooler Heat Exchanger and Oil cooler. There are shrouds and foam around everything to keep it pretty well sealed, which is good in that they have it sorted from factory, and bad in that I can't make any meaningful improvements there. The second red sport pump water pump is mounted in front of the rad in the airflow, so I will see if there is somewhere else I can stash that (unlikely, it is tight in there). The horns which are also in the rad airflow will be moved somewhere else, and hey who needs 2 when 1 would work For track days, I can also remove the lights which would block some airflow. Factory has already taken the smart option of ducting all air that went through the oil cooler down and out of the engine bay. This pic is taken from below looking up, so air comes through the cooler at the top of the pic then hits the shroud and is directed down and out of the engine bay through the engine bay lower cover Which of course is good for oil temps, but doesn't help the rad as it diverts 10-20% of airflow away So, no big improvements to be made here, I'll flush the rad out and put it all back together.....    
    • It looks so incredibly busy in there! 😮 
    • Next..... That escalated quicker than an Elon and Donald break up! I'll post up a specific DIY for radiator removal on these, but all I'm saying is that if you get a workshop to change your radiator for any reason and they give you a $1000 bill for it, go and hug them and thank them for not charging all the hours it took.....what a bastard of a job. I'll make some adjustments as I put it all back for faster access in the future, but it was a nightmare.
