Mild 408 build #'s
Allngn, I had a really bad 60' and still ran a 2.0 lol. That is good for street tires but horrible for E/T Streets
I am not running bias plys though, just a 275/40-17 on black ZR-1s. Let me know what you end up getting when you run the 1/4... The one thing that I did which was a horrible idea was when I put in my McLoed Master I did the drill mod. Now my LS7 clutch feels like a damn puck. Learned my lesson on that one, still trying hard to get used to it.
