Iron Indian

I've been 10.94 @ 124 previously. After that run I had to upgrade my stock diff to a 9" IRS which reduced my times to 11.0 - 11.1 @ 121 range with the same low-mid 1.6 60fts

Only change this year is 15x4 Skinnies to get rid of the 18" street wheels. That small change made all the difference in the world. Here's my new PB...

10.809 @ 124.70 w/ a 1.52 60ft

I backed that up 3 times with 10.8x with low-mid 1.5 60ft. I would of never guessed Skinnies could of impacted my 60fts so much. Although the 9" robbed me a little bit of power, the reliability and the true posi diff makes it all worth it. The stock LSD sucked.

Here is my mod list for reference...

Congrats!! Great color on that goat. Skinnies makes a difference for sure. Less weight and rolling resistance!
