As far as getting traction i recomend the Nitto Envo, I launch consistantly at 2000 rpm's and have yet to have it break loose. Although adding a pulley and intake might help with the chances of it spinning out. i went to a 285 in the rear and a 255 in the front, i set the air pressure at 25 lbs and run all night. Dude there is video on youtube of an SRT6 with pulley and intake and it did 12.4 at 110, so I hope you can beat that cause it would be awesome!!!!
