Im considering the lowering kit since ill have around 3" of lift from stock. I have JBA UCA's and the same eibach spring set up as you on order.
Couple questions:
Does the diff drop affect ground clearance in a negative way?
Do you think gas mileage is improved with lowering the diff? Random question that isn't important, I am just curious.
Technically yes it slightly reduces clearance. Not sure on the gas mileage.
