You will be pushing a lot of air even though its lowered. Don't under gear it so the engine has to work all the time just to keep it going. What engine are going to run? what transmission? With the right hp, a overdrive trans will solve a lot of gear ratio problems. You can probably find 4.10 through 4.56 pretty easy and with a decent tire hight and overdrive, they would work out great. Good low speed power, yet easy driving out on the road.

Axles of this size should be of the eight bolt lug pattern, you sure you can find the wheels you like with that bolt pattern?
