Do that in the light tomorrow...Have you got a picture from further away to show where it is?

Undertray..? Deeper and deeper we go into the rabbit hole! Manual on the kitchen table tonight...Yes, there should be an under tray that it attached to?
Further check of the full manual last night does not show or mention an undertray - without such a thing the back of the bumper is open and seemingly acts like an air brake. This is what I saw when I first looked. Am I missing something here? If this is the case then the blowing out of the upper bumper edge will need reinforcement. I wonder if the reinforcing bar is an on the job fix by Maserati or the owner? The rear bumper fixed on my car definately is not reinforced but the replacement scrap one is - as does the bumper on car picture evidence you guys sent back. Will check and take some photos in the light of day and get back to you all.I would have thought there should be- and from your comments about it's acting as n "airscoop" too. The 4200 certainly does....but I scanned the parts fiche on Eurospares, probably not definitive, and it doesnt show one....!
Curious...
A small deflector would make sense - mine definitely does not have one but I could make one up and bond it to the wheel well - so long as it does not affect the airflow over the lower wing and make the car rear end 'light' at speed.I reckon they used whatever they had lying around for the reinforcement, mine is a w shaped piece of aluminium.
There is a vertical piece of metal, looks a bit like heat shield between my spare wheel well and the upper part of the bumper if I remember correctly. Will have a look after work in case I’m wrong.
Yup. I am just as puzzled as you. Going outside for a look-see. It's going to Giallo for an MOT next week - will ask Mat's opinion.Looking at the photo I posted earlier it can’t come down very far or do much that affects air flow. Or maybe I’m mistaken as to what’s there.

Wing base is on the left - Excuse the deck chair.! Can’t get a good enough picture of the top edge of the rear bumper on the car, which is distorted.The big picture:

Foxed!Just had a look. No undertray on mine and it doesn’t have those two tabs either.
Made by? Does it repel idiots?While you have it all to bits sir you might want to look at the eletromagnetic parking sensor I fitted to my car which is a metallic strip stuck inside the bumper and cannot be seen outside at all. Its not the best parking device i have ever had but it works more or less. I fitted it to my car when i had the bumper off.

Curious. W shaped reinforcement would be stronger but flatter - the surface normally has a natural slight curve.
Dave. You out there?
165! That's ten short on the blurb - makes you wonder if that extra ten was lost because of the air brake effect of the upper rear bumper design? Small things make a massive difference at that speed. The underside of the 3200 is very turbulent - there is no downforce wing above - the car seems to rely just on its upper body shape and the clever design of the lower wing bumper to hold the end down at speed. I am no expert but its a pity that Guigiaro - or the manufacturing process - handicapped it with what is in effect a small airdam 'brake' above the lower rear wing. It will be interesting to see what effect - or none - filling in the small distort gap above the air tunnel will have. It should make it a whole lot smoother aerodynamically at this critical point if I can find something to fit and fill it - it wont be that obvious to the outside but... I feel sure she will appreciate it.They achieved 175 flat, well the manual cars did according to the blurb at the time which I don't believe either!
I had 165+ out of mine a few years ago, it was stuck to the tarmac like glue so there must be lots of downforce from somewhere!
