i ran a 14.50 at 96 mph with my 88 lx and it has those tires... i feel i could have gotten more about a 14.4 but i dont believe it could have gotten it any lower.. but i ran out of runs any way..but gettin traction was the issue...ppl say with a trap speed like that i can get a 14.2's....will changing to z rated tires help with better hook...im just wonderin...i thought z rated tires would be harder since they can handle more speed...any thoughts
