Is there any guide on car setup for this track. Racing cars (standard setup) reacts too much on bumps and curbs can t drive

I don't think there are any guides to car setup on this particular track; anyhow, try to read the general guide by Scaff in the Gt4 (I seem to remember) section of this forum to find some advices.
If a car reacts too much on the bumps, try to soften suspensions (reduce spring ratios), increase ride height, reduce dampers action. That would help, as a start. Doing this you'll sacrifice some driving precision, so try to find the best compromise between reactiveness (reactivity?) and precision.
