Rick, how do you stand corrected? now talking about weight, I could have dropped my spare, and my smog pump, and maybe dropped an extra tenth? so with e.t. streets, and before all of the mods in my sig(wow my `oh so powerful mods) i could have gone 13.8's. It has alot to do with driving, im still using a stock shifter too, On my 13.9 run i was launching at idle, thats all my 225/60's would take, i'll admit, i only ran that once on street tires, and the electric fan and swaybar removal isnt stock, but I believe all stangs should have came with electric fans.
Then again i see guys running stock fox gt's that can't break outta the 15's, even with gears and free mods.....
