Just got back from the track. 1st time with new slicks. Lost in the first round but set a new best time of 7.97 @ 87mph. Also new best 60' of 1.74. According to the conversion chart I have, this is roughly the equivalent of 12.43 in the quarter mi. Not too bad for leaving at idle (I don't want the 7.5" to scatter as I've got a hour drive home with it).
