i did a quick search on here and found this.. some really smart (and attractive) dude posted it http://www.wallaceracing.com/calcrgr.php

it says 3.68 or under for stock rear tires

i run a 27" tire which would allow you to run up to 3.87

So if I want to do 165mph+ in the 1/4 with 26" tall (335/30/18's) I should install a Viper 3:07 IRS out back....?
