    Here, we can see the pipes to lead fresh air to the rear brakes of other cars. It seems that Hyundai removes the sticker on the inlet which was there in MC and Sweden (low temps for these events)

    An interesting thing is that there are three channels in Ford - one presumably leading to the rear differential and two seem to lead to the brake but why two? Do they intend to increase effectiveness by sending the air on larger area of the disc or is it for some other reason (or cooling of different part)?

    Also I haven't seen yet any photo of Yaris with hoses installed at the rear axle. Do they use them at all? Also the damper canister is at the frontal side of the strut i.e. possibly affecting the air flow coming to the brakes (not that it wouldn't enjoy some cooling).

    It's also interesting that Hyundai has the air intakes so high under the windows. I guess that it must be to prevent dirt coming into the air channel.

    Yes, there were pictures of C3 with that hole full of gravel before they put a net. Hyundai invented it much better.

    I wouldn’t be surprised if, of the two pipes on the Fiesta leading to the brake system, one is delivering air to the centre of the disc and the other to the calliper.

    Is it possible the hose is traveling via the diff, and then outward, blowing perpendiculary?

    Can someone tell something about different gravel tyre profiles, what is the difference...?

    Here we can see one Michelin option https://pbs.twimg.com/media/C6WNfoCU4AAy7Su.jpg
    Here is an other (as far as I know this one is more used) https://pbs.twimg.com/media/C6QdjXNVUAEnzjU.jpg

    I think that this year WRC and WRC2 tyres aren't same. The new cars with much more aero downforce and stronger engines need more durable tyres.

    The trailing edge of the floor at the junction of the rear wheel arch on the Hyundai seems to have a diffuser like profile. Ie, the section of floor between the front and rear wheel arches ends with a curved profile at the rear. Possibly the Toyota also?

    What are the black tunnels on the Citroen leaving out from the rear boot to the bottom? Seems a bit extensive if it`s just cabin pressure removal, and if it was that than why lead them to the bottom?
