Ok I take back the slicks comment.  I didn't see that you were running DR's.  So knock off a tenth or maybe two for the slicks, maybe none....A bunch of people are actually running faster with DR's.  I would think with all that, you'd be pretty close to 13's.....but you never know, until you try it!
