Performance Question with D60's
So, I am the white JK that made the mistake of going with WW and Lefthand Rubi up CC. Because of the great experience, I recently had to upgrade to Iroc 39.5 Superswampers, Dynatrac 60's with 5.38 gears in my JK 2 door. I was running 37" KM2's, Dana 44's with 5.13 gearing, and a Ripp supercharger.
I am waiting for my Dynatrac's to be built, but I am a bit worried about on road performance (increased weight of the new tires and the D60's). My question is, what will my on road performance be (ie can I drive the speed limit to the trail) in a 2 door JK with the 3.8 stock engine, Ripp Supercharger, Iroc 39.5's, Dynatrac D60's, 5.38 gears in Colorado at the speed limit? What will the performance difference be between my current set up and the new one?
Any thoughts are welcome. I am also trying to imagine performance changes. I don't know how to figure that out, but am looking for experts to advise.

Regardng your question: I would think you have enough juice with the Ripp to move your rig. You will have to watch out with the rubicrawler and 5.38's. Should be ok, but that crawler makes for lots of power.
Someone on the forum has pretty much the same set up as you will (sans Rubicrawler)---their name is escaping me....
