1. Regear will be subjective from person to person but you may want to regear with such a low gear. If you plan to go with bigger tires in the future then I might go with a gear aimed more toward that. A 4.88 would be best though as the 5.13 in a D30 has a really small pinion. And I think OffRoad Evolution runs that $999 gear special all year.
I think I going to give OffRoad Evolution a call to see hat they can do for me. It that's all it cost I just might regear it now. In Hawaii it was a few thousand for it. Thanks
