Hi, xlr8, congrats on getting your license! I too am curious as to what tire pressures you might be running, from the first pic on the post the rear tire is wrinkled a bit which suggests pretty low. I run about 10 psi in my similar car running similar ET and MPH. Someone posted above what front tire pressures might be as far as contributing to bounce, I don't see that as relevant, but I could be wrong and am willing to be schooled if need be. Do you have a parachute on the car? I do, and I do use it every pass, at 125 MPH or so it won't try to pop your eyeballs out of their sockets, but you CAN feel it helping to slow the car.
