Great posts.
One thing I noticed though, just above LM3's right headlight there seems to be a filled-out hole where previously there was one of the later-deleted eyebrow vents. It appears that the McLaren lads are simply going to cover it over with the orange panel of carbon fiber currently resting over the right side wheelarch cooling vents, rather than mould and autoclave a new solid panel without the vent hole.
Anyone know anything about this, and whether the same is present on all F1s?
