    Anyone else having a issue of GT/LMP cars dragging on the banks at Daytona?

    Even with ride height all the way up and bump stops the highest they will go, Im just dragging all the way thur the banks at daytona road course. All the way thur the banked corners is just constant scrapping sounds and the car just turning extra stiff from it just laying on the pavement so bad its making my eye balls shake from watching the screen. Does it just as bad with low fuel as it does with full fuel in every gt or lmp car. Any idea on how to fix or cope with it? Maybe something in spring or dampers i can do? Default stable set up, except like i said i have to ride hieght and bump stops all the way up trying to raise it up.

    Maybe you're just riding the bump stops. You don't want the bump stops too high. In the Ligier cars 55mm front, 75me rear height with 10mm bump stops is plenty to keep it off the ground (0 wing, ~180 springs).
    The GT cars stay off the ground easily too. The bump stops are noisy. Again 5mm bump stops on them are plenty.
    I hit the bump stops a lot through the banking on Daytona.

    the gt and lmp cars drag, beat and bang, even more when i lower the bump stops to a normal level and the scrapping sound is longer. The cars just sit down on the pavement until i get off the banking. i will try 0 wing after while and see what that does.

    This is about how much downforce is pushing down vs how stiff your springs are vs your ride height. You'll need more ride height and stiffer springs to cope with more downforce. Even on low wing settings will create a good amount of downforce at high speed. I highly recommend stiff third springs and soft regular springs on LMPs with low ride height.

    Yeah if I’m driving just the oval, I’ll set up the car asymmetrically with the ride height higher on the right side and I’ll experiment with that until there is a minimal amount of dragging. Take a look at how Indy cars are set for ovals.

    At 0 wings they still make a fair whack of downforce. Have you checked on the telemetry screen? When I’m on the banking I’ll get flashes of red on travel getting low (springs bottoming out) but the height is still >20mm, including a lot of scraping noise. I deduce that’s the bump stop noise because my car wasn’t slowing.

    Even soft-ish 3rd springs hold the car up great, really.

    .... your right, that does seem to be the sound of me riding/hitting on the bumb stops. Silly me, I thought it was the sound of me dragging the ground. I probally would have never figured that out on my own and it would have never dawned on me thats the sound of the bumbstops. Thanks

    It's odd. I don't expect sound from compressing bits of rubber.

    seems that, what ever is making it. It happens when the suspension is i guess, compressed or pushed down as far as it can for the lack of a better word, on what would I assume have to be the bumb stops.

    Definitely have had a similar issue, specifically with the LMP cars. It almost seems to bog down until I exit the turn. Very annoying.
