Fiream;
OH NO NOT AGAIN!!!!
That's one rough looking track. I've raced on Off-Road tracks with less bumps...
just kidding, well almost.
From the looks of that surface (Well worn Asphalt?), I recommend Yokomo 138G's. They usually work best on a rougher surface as you have there.
If the chassis is bottoming out on the bumps, then raise the RH by 1mm. You could also try a few steps heavier shock oil too. The Traction should be great except for the jumps (bumps).
