    I went to see this scud today and the RHS carbon panel has gone nearly white. Also, if you see in the picture the panel gap between panel and frame is much smaller on the RHS vs the LHS. My questions:
    1. It it normal for the carbon panel to deform as well as discolour
    2. Has anyone else had this issue and how to deal with it.There ways to repair discolouration but i suspect if deformed then the car needs a new part
    3. What may be the causes as its only on one side. The other is perfect
    4. Is this deformation common or can it be hiding a structural issue underneath?

    In addition the exterior bolts that hold the glass engine cover were dark brown rather than black which I would have expected. Do these come in that shade or do they also discolour?

    Many thanks for any insights in advance.

    Hehe, I'm just free associating and obsessed with my exhaust ecus. The computer will cut fuel and run lean if the exhaust ecu shows high cat temp. Lean is not good so I jumps to a conclusion of free associated. I'm a newb so it was just a thought. ;) Explain what would really happen under lean conditions.

    The resin batch used to mold the CF wasn't mixed properly.

    ... and the discolored hardware tells me it may have experienced excessive heat.

    Heat and UV light are the two things that are at play here. I'd need to see the back of the panel to see how it was made, if it was made with Autoclave and pre-preg carbon it should have UV stabilisers in it. They can be refreshed I've done a few but the colour of the resin will still be brown in places.

    I have similar "milking" of the clear coat of my RHS carbon fiber panel. Almost exactly the same although not quite as bad. It must just be a hot spot in the engine bay.

    I plan to remove the panels some day and have them sanded down and recoated with clear coat. I know of a shop who offers this as a service in Atlanta, but I haven't researched it since I've been in LA.

    Maybe one side was replaced (fresh looking), and one side was not (white)?

    Also:
    Mine are all black, but the engine cover is a "plastic" and not glass..... are you sure it was glass? Is this a real Scuderia?

    It felt like glass. I queried that as I have a CS and it is plastic. I was told that scuds have a thinned glass cover which is lighter than the standard 430. I seem to remember that I have heard that before. Is that correct?

    Anyone had the bolts holding this panel discolour and turn brown or ordered brown (is that even possible!)?

    As for one side being replaced vs the other, I did a search of the cars that are for sale in the UK and from quite a few that had engine pictures, you can see this problem (maybe not as pronounced as the one I drove) and apart from one car that was the same on both sides the others were all on the RHS only!

    The rear "glass" panel is plastic. The bolts holding my panel in place have also discolored from the sun/heat. They have a purplish-brown hue. As for the CF panel, I doubt it's an issue of one panel having been replaced as, like I said, I have nearly the exact same discoloration. I'm taking my car for a drive this morning. I'll try to remember to take a pic.

    Thanks Dave. Does the panel feel like plastic or like glass. The one I saw certainly felt like glass.
    I am wondering if it is possible to put a standard 430 panel if you have damage to save on cost?

    Re the bolts that's also very helpful info!

    Don't worry, it feels like glass.

    As far as I know the F430 Coupe glass doesn't fit for the Scuderia.

    See Eurospares:
    F430 Coupe part number 68074900 (Ferrari 430 Coup? - Glasses and Gaskets: Page 120 | Order Online Eurospares)
    430 Scuderia part number 80426400 (Ferrari 430 Scuderia - Glasses and Gaskets : Page 121 | Order Online Eurospares)

    Call Mc Carbon in California - I had the same problem - only 1 side - took out all cf in bay and shipped (did all parts so would match when done)
    They redid perfectly and backed the large panels with insulation = put back in and looks perfect - costs about $5500 plus 4 years age

    Push down on the panel. If it flexes, it's plastic.

    Here's my engine bay. Might look familiar to you.

    Are you talking about the 4 side panels only or also the air box and radiator fill tank covers? I was thinking of just doing the two large side panels.

    That sounds like a hell of a lot of money for a CF fix. I had my inlet manifolds and engine bay carbon parts reconditioned for £1200 last year. Otherwise just get pattern parts and keep the originals for refit for resale

    That sounds very expensive. The longer side panels are about GBP1600 from eurospares and I believe they are original parts. I guess Mc Carbon may be more costly as they also do additional insulation.

    Wow that is very similar!
    When you say to push down and if it flexes its plastic, are you saying that it would not be a cf part but a cheaper substitute?

    Looks like eurospares don't have a scud panel but maranello parts do and ti costs the same as one of the long carbon panels (GBP1600). i would have through it would be a more expensive item!

    Plexus is a clear plastic used as a glass replacement for the rear window. It's fitted to Scuds, CS and Challenge race cars as standard. The carbon cross beam are also fitted to stop the plexus from deforming due to the heat of the engine bay.

    I thought dave was refering to the cf panel no the engine cover.
    When I pressed on the engine lid it did not flex unlike my CS which does.

    Exactly why I asked. Might want to look at the car a lot more carefully.

    Paperwork and all numbers were matching and it was all scud... Maybe I didn't press hard enough!

    Sorry, I was referring to the plexi panel, not the CF panel. Strange if yours is glass.
