I just got to the track this weekend with my first set of slicks. I drive a 84 F-150. The beginning of the night went well but the weather rolled in and temp dropped to about 55. It was 75 and sunny earlier.

Well my question is when I was launching later in the evening my tires were still breaking loose. I did hook up okay but I could feel the slip off the line. I was running 11psi in the tires and had a half turn in on the caltracs. I'd stall it up to 2700 and let her go. Early in the evening the tires stuck good but when it cooled down I couldn't stick it. I was getting a good burn out prior too. Any advise would help. I'm pretty new at this. The best 60ft time I could get was 2.0433. That was while it was still warm. After it cooled down I'd made adjustments and with the tires breakin loose was getting a 2.49-2.62 60ft times. Thank you all.
