Yesterday was my 3rd time @ the track. I don't go a whole lot. I've got 255/45/17's all the way around, and I don't think they're even Z rated. Anyway, If I launch over 2,000 rpm the back end will just bust loose. I think around 2,200 is the max I can launch. I have 4.10's & 312 rwhp w/ 342rwtq (SAE Corrected). My best time so far is 13.46 @ 106.5 mph. Will it get any better with street tires or do I have to get slicks / drag radials? ALL LAUNCHING TIPS ARE GREATLY APPRECIATED!!
