I don't think it spun, pulled good out of hole i had 18 lb in tires on 10 in. rims, two air bags, pass side 25 lb, driver side 5 lb, that was my best time and speed other were 95.3 mph @7.6 sec, but i think i have fuel issue now, fp seems to be falling off when i run it on longer 1/4 mile run on road but i have no times because it just a rd they haven't finished yet and ZMAX doesn't have test and tune this year
