I went to Cecil County Drag Strip and could only turn 13.32 @ 112 MPH. The problem was wheel hop in 1st through 3rd gear. I lowered the rear tire air pressure to 25lbs and still had to feather the car out of the light and get off the gas in 2nd to stop the wheel hop. I did not do any burnouts prior to each run. Additionally, there was another Z06 who ran the same numbers and had the same problem as I did. Any suggestions. :-?
