Here's how the Pros Do an Underbody Fairing

Check this.... So you've seen the pictures of the underside of a Lotus Elise (poor goodyear accident/debacle).... Well, how about a Noble M12 GTO (twin turbo v6)?





Here you go




I also have a picture of the diffuser if you want to see that. And the interior is beautiful

Now, if you EVER see me design something that sh!tty.... Please slap me in the face (at least). To remove that front panel... First - remove the bonnet, then reach under all sorts of stuff to unbolt 6 bolts... Then drill out 104 rivets.

Then, pull hard (without bending) - because that sucker is glued on too!


Why is it riveted? Well, honestly - there's no other way to get a really high stiffness without permanent fasteners.... Bolts can do the same - but requires a LOT more work and likely would be more difficult (to get to the other end). If it were me - I'd probably go for a larger tube for the frame to get better stiffness.

Maybe it's masquerading as a monocoque.

Does anyone know anything about the ease of removal of the various Ferrari models' underbody panels?

I guess it's a hybrid monocoque/tubular space frame We should totally put a hybrid sticker on it

The car is Mid-engine Rear drive and by the looks of it there are some access points for the oil filter at least (or possibly a filter relocation kit on it?)

But accessing the front Suspension components does not look like any fun. From the pictures I've seen on the net though, it isn't all that bad once the wheel comes off and the bonnet is popped.

Thought the same, but

Even though it's a mid-engine design, I can't tell if the tray extends to the point of the oil pan.

More newer front-engine cars have a factory partial-undertray with a hatch to access the oil pan (the TSX has this, and yes, the oil tends to splash onto it when it first drains) Otherwise, IMO the aero benefits outweigh the inconvenience.

But back to the M12's tray -- what an injustice! I'm sure it helps with air flow, but the rivets and heater vents probably do not. I think I'll try Coroplast or something cheap and functional. The problem is, local Politicians went to a plastic-bag-style sign (thicker gauge) and it's harder to find "Free CP".

Something needs to go on the 'Teg, but an intake re-route for summer has to go in first (engine compartment air = source: reaching 130's again). Good on cold-starts, bad after 5 minutes I just need to make the time to do it...

The rear end in front of the diffuser is exposed for access to the engine underside

So it's basically a re-bodied Fiero?
