So I have made over 20 something passes on my new Phoenix slicks and spun every time. After watching the videos of my car it looked like the tire was wadding up bad at the hit then the spin begins.So I installed tubes and 32 rim screws per rim and went to the track tonight. The car hooked hard every pass and pulled some rear wheel 60 foots. So it you are having traction issues try tubes and rim screws, it sure helped my car. Here is a gopro of my last run tonight.
