I've hit 11.992 on street tires, can't seem to replicate the feat on "slicks". Running MT ET Street 26x10.5/16 on 13lb MB Tolimann wheels and have tried every PSI from 25 to 15. I'm thinking I need to wait for better DA to try again. My advice is to practice practice practice until you know how the car reacts to your foot. My first runs were 13.7-13.8 @ 105 and I've dropped that almost 2 seconds in a few years. Driver mod is always the most important mod!
