I have the same setup as you and I just installed a 12 bolt with 4.11's. I hope it helps alot. I was having to shift into 4th right at the first set of timing beams and my mph and et sucked.

I dropped about 3 tenths going to 4.11s. Traction becomes the issue quickly. My Nittos would not hook over a 2600 rpm launch.

What happened to your MPH in the quarter? Up down or no change?

i went 5 tenths with the 12bolt and nittos but kept the exact same mph because of the much better traction and 60's
