    Oh heck yea,i can't wait for rally, i completely forgot about that, i wonder if they are also working to improve the rally physics.

    Hopefully they fix the degrees of steering on dirt/snow tracks. I want my full 900 degrees.

    Shouldn't high curbs easily disrupt the car's trajectory and/or the balance? I can see that balance wouldn't be an issue since we're taking about a car with slicks and downforce.

    Hopefully, the suspension and tire model improvements should transfer to the rally portion of the game. It would be annoying if the physics had to have a different behavior just for rally to work.

    Part 2 & 3 doesn't really show how much more real the suspension works.

    The inner curb in the second corner is still not right. In reality it is more flat and wider, so you can drive over it and that way have a faster line.

    It is nice to see the suspension work. Looks promissing.

    Anyone else excited to give the Formula 1's a go? i really am pumped to see how they handle now.

    A lot of bodyroll and wheel lift off :)

    Love the body roll. Watching replays is going to be soooo much better.

    I just hope they will add slow motion replay, at least for a short sequence, it would be a good feedback to help to set the car understanding better the motion,dampers working..., together with a good FFB at the wheel.

    But does that really happen in real life I mean that 370z looks like it could topple over..a small amount of turn would lead to only a small amount of roll etc. Here it looks like the car lists by a huge amount at every turn.

    In the real world, the body roll on onboard cam is barely noticeable..
    I don't know guys, but I think PD exagerate the body roll too much and it looks really weird and arcadish.

    Compare the first video with this one..

    On-board cams are never great for determining the degree of body-roll, that's also a soaking wet lap around the 'ring (in which only the insane would push the car 100%) against a bone dry Silverstone in a game (which will allow you to push 100% with no risk).

    Then please explain the pictures I posted of a real 370Z with as much body roll as the GT6 one?

    Now here's a little puzzle for you, of those two cars in my picture one is running stock suspension and one is running modified suspension (stiffer), which one is which?

    No, you cannot really see body roll with an in-camera but that's partly because it moves along with the car. Body roll is something you mostly feel with your body, you just know it's there and I believe that until we all get moving seats, it's a really good way to simulate that feeling.

    I think the reason might be the tires, which were selected. If it was let's say on sports hard, there could have been too much grip.

    Actually the thing I'm expecting most of GT6, apart from new tire and physics model is the standard true-to-life tires being pointed out for every car by Polyphony. I wonder if they will let us know finally (by making a list, or option to choose) which tires are stock.

    So far I've only seen in demo that KTM X-Bow has Sports Hard as default, which kind of makes sense. But on the other hand almost every powerful car in GT5 had Sports Hard as default.

    Yeah, it's been deliberately exaggerated in bumper cam etc. since GT4 at least - the exaggeration allows for small changes in angular acceleration to be much more easily detected by eye (when you'd usually do it through your body and inner ear).

    These kind of small changes occur when the car just loses grip. I.e. it's supposed to make detecting the edges of the grip envelope a bit easier.

    Interesting tidbit ,Are the R8 and GTR driven by the A.I ?

    I would guess the second of the 2 is the modified suspension, just looking at the ride height and the angle of the car when you look from front left to front right wheels. But that's just a total guess.

    I guess the first picture is the stock one

    But this has nothing to do with the body roll I talked about in the GT6 video.



    In the above GT6 video, especially during 0:33 - 0:40 the body roll is wayyyy to much and too unnatural.. it rolled, and it instantly bounced back to normal position.. it looks arcade-ish..

    in this real world video:



    Watch carefully 1:25 to 2:15
    The body roll feels natural and not that much compared to the GT6 video.

    Watch the roll of the BMW in front..hardly any at all. To get the body to swing like that you have to really chuck it in presumably while breaking to shift more weight over the front axles..Not just be driving straight and making a bit of a turn.

    It is. The second picture (which shows much more body roll) is fitted with stiffer springs and dampers, but has wider/lower profile tyres running a softer compound. As such the forces on the car are far greater and despite the stiffer suspension you get much greater body roll.

    Factors that influence body roll have nothing to do with body roll?


    Of course its more exaggerated when using in-car in a sim, you don't have g-forces telling your body what's going on, so exaggerated movement is used to help let you know whats going on. Why? Well because it works.

    I would however agree that work does need to be done on the dampers, but we do know this is not a finished build.

    The external body roll is not that different and the internal differs for the reasons I have outlined above.

    If I can only have one thing added to the game, I would want tire temps. Temps inside, middle and outside on each would give me everything that I need to perfect a tune.
