I have a 96 Z28- 75,000 miles. I went to the drag strip this past weekend, and I could not get traction to save my life. I have Nitto 555R Drag Radials, and a 3400 stall, some bolt ons. I am usually 1.9 60 foot. This weekend I was 2.0-2.1 spinning most every pass.
Traction was so bad, it made me wonder if I was getting only one wheel driving the car. I had my wife take a video from right behind the car, and both tires spin for the burnout, and spin coming out of the burnout. The car does not make any noise, and it tracks straight.
I don't think the track was prepped that good, since it was more of a street car race, not a regular bracket racing program. This all might be in my head- but I just had to see if anyone else has had an issue, where everything was ok with the Posi unit 'till they left the starting line on a dragstrip?? Any test I can do to see if its OK? (Maybe a big burnout on the street to see if its laying down 2 strips??
