Bottoming out all the time

[Polkadot9000 0]

I can't figure out why, but I seem to be bottoming out all the time with a ride height of 5,5 aero of 6,6 and spring strength of 7,7. with rollbars of 6,6 (i believe) I've got  most of the chassis upgrades from the first season, but no engine or aero upgrades. I bottom out at around 150 mph on the straights. I also sometimes bottom out around high speed corners.
