When I dead hooked my coupe I got the best 60 ft times at 1.6. That was with drag springs 90/10's and four cylinder springs out back with eagle f1 tires. One day I hope to take the gt out to Ennis and see what she'll run.
After looking at my signature, it is kind of funny that my 17" ET Street timeslip is better than my 15" slick timeslip. I know on the slicks the car spun less, and sometimes not at all, whereas they always spun with the ET Streets.
My understanding was its easier to make up for rolling resistance with a stiffer sidewall on the big end rather then a softer wall and a car that doesnt have the power to do so, or something like that.
