i know all cars are different, some like higher than lower and that the type of car matters, as does weight. but, my question is for me and my car.

its a 9.6 full body camaro weights 3050 with me in it, i got 8 lbs in my big tire car. my 60 ft times however have no reason to them. i've been at low as 1.31 for the first run of the day and i've had 1.31 as the last run of the day. unfortunally i've also had a few 1.35 and some 1.37. this as we know is death at the finish line. your either holding a ton, or you hope that your oppounet had like a .110 r/t since you don't have a pray of running the number.

I have 28x11.5 on the back of my Firebird and run between 10 1/2 to 11. This is a footbrake car. When I ran 28x9, I ran 11.5 to 12. I use M/T bias ply's.
