After a trip to the drag strip I need some help off the line. I was able to get a best run of 13.19 at 110mph. I guess thats not to bad but I really thought I could get into the 12's. My 60 ft was 2.16. I wheel hop bad in first and some on the second shift. I'm running Goodyear F1 GS-D3 tires in 245/40 18. I can't use drag bags since I have eibach springs. How much help if any would drag radials be? Any brand get better results than the others? Thanks for any advice.
