Yeah, 60ft times were in range of 2.2-2.6. Running street tires so I dont break anything. I was just interested in finding out the MPH. I have 3.33 gears right now and I am installing 4.11's this weekend. That should put me in the 11's for sure with the street tires and pick up 3-4mph also. I was still in third gear going through the traps with the 3.33's.
