Is this too much tire hit?

The tire pressure all revolves around what pressure "your" car performs best with. In the Dakota, we ran between 7.5 & 11.5 depending upon conditions & how the track is prepped. Once we had brand new tires installed before the first T&T run, it almost stood on the back bumper with 8.5 in the tires. We upped the pressure for the next run & it settled it back down to our normal leave, front tires appx 2" off the ground, 1.57 60' running I/CM in Baton Rouge, LA.
