I have a new combo "mods in sig" and this is about my 3rd outting to the track. I launched it today at 5k an the results were 11.12@126 w/ 1.68 60ft. Now I have been launching at 4500 due to lack of 26 spline input shaft, but the car wont 60 ft like that so.....what do you guys launch at? Also I'm running 26x11.5x17 ET streets the bias ply ones not the radial.
