Suspension bushes?

[Blue Dog]

Seriously considering purchasing your front & rear kit to suit an FG MkII XR6 Turbo ute.
I'm happy with the factory suspension height so am not interested in going lower.
However the adjustability of the suspension height is appealing if only to level the vehicle.
Would you recommend installing an aftermarket product such as Superpro bushes over the OEM rubber bushes, or perhaps a combination of both to compliment your kit?
