    Thanks for the link. I've checked the article shared by @ingegnere about Ford's rims. They claim a weight of 18lbs (about 8 kgs), which isn't far off Koenigsegg's numbers (6.5 kgs). Carbon Revolution also says that their CR-9 wheels are about 40-50% lighter than OEM aluminium rims, a claim in line with Ferrari's (-40% compared to GTB standard wheels).

    Here's the quote from their website (http://www.carbonrev.com/faq)

    Q: How much lighter are they than my stock wheels?
    A: "CR-9’s are between 40-50% lighter than the OEM aluminum wheels they replace with no decrease in durability or stiffness. CR-9’s on a Porsche 911 reduce the un-sprung rotating mass by over 40 lbs. (almost 20kg)."

    I would seriously doubt the software for the fluid control cares about the materials of the rims. The sensors work as they do and would run off the action of the speed of the shock shaft. If it moves a little faster then it should be handled by the standard control system. Remember, some rubber tires weigh considerably less than others and there's no setting for that. On a motorcycle you can better feel the results of reduced sprung and unsprung weight. There the suspension is also manually adjustable for racing in both high/low speed rebound and compression along with spring adjustments for race sag and static sag. The Pista is not a race car so no need for any such concerns.

    Excellent question. I'm not sure what they are doing now, but on the 599 GTB in the owners manual I seem to remember a mention if you were to change between the optional run flat tires or regular you had to have the suspension computer reprogrammed for just this reason.

    It may well require a reprogram if you switch between these wheels, or perhaps they have put it in the car's setup menu: select which wheels you are using. Its also possible they have figured out a calibration that is acceptable for both wheel and tire assemblies, or as you say, it self calibrates.

    Its not just reducing unsprung weight from rebounding, its also less rotating mass. The net result should be that things happen that much faster and more precisely. Will a keen driver notice the difference? That is my question. I am leaning toward ordering both sets of wheels and running the forged metal wheels for the street and keeping the CF wheels for maybe a time in the future I want to change it up. I would like to learn some more before I make the decision which setup I would run for the street. But it is fascinating.

    One thing I noticed on the OEM website for CF wheels, they have a video testing the wheels and they show just how much give they have. Its quite a lot more than I would have expected. I would have expected the wheel to bend slightly, then fracture. They really do bend, and then it seems they return to their original shape. Whereas metal wheels, even forged (which are best for this) will after some force, stay bent, or as I'm discussing it, they will become slightly out of round. This shows up as your car feels like its balance is off after a few years when you are driving over crummy roads many of us have. You don't have any obvious signs of damage, and you haven't hit any big potholes, yet, the car shakes at certain speeds. The standard cast wheels (this goes for anyone) are IMHO just too soft and prone to this. The forged are much better, but will still be susceptible to this. Not too hard to get your wheel and tire assembly road force balanced and that should sort it. But it does seem to me another advantage of the CF wheels is they would not be prone to this becoming slightly out of round over time.

    Fantastic pics thank you!

    Does anyone know what looks like either springs or some kind of expansion area on one of the headers does? It looks like its on both sides of the engine but only on the headers closest to the passenger cell.

    Those are bellows type flex joints. They are used to reduce the bending loads on the tubing which would exist without them due to thermal expansion on the tube and the fact the tube is basically constrained at both ends.

    The fact that only the first branch of exhaust has this flex joint may be due to its particular shape or the fact that it is particularly long, so experiences most thermal expansion, or both ;-)

    Not sure if previously discussed and apologies if so. What are the wheel finish choices?......Obviously there is silver and carbon fiber. Is there a grey/charcoal, diamond finish, etc? Thanks!

    If I recall, the 458 Speciale standard wheels were five spoke in smokey grey as well.

    You need to see a 458 sitting next to a 308 in the flesh. There's no doubt about where they were drawing their inspiration from.

    Inspiration does not mean retro. Retro is a tribute to the original, like the 2 GT 40’s

    This is not a tribute to the 308 or the 246 Dino before it

    Yes I understand. Others have since I posted there is nothing retro about this design.

    When you order luggage set, is it like for the model scale you receive after you have sold the actually car or you get them early enough that you can use them???
