i had an ARB with the 20% stiffer bilstein shocks and it felt well controlled. cranked up the torsion bars alittle since your front end will sag more. a year later i added a winch and sway aways with a 3" lift. if you do get a winch i'd recommend getting the sway away torsion bars (or another more heavy duty torsion bar) since they are 20-30% stiffer and can compensate for the additional weight.

you can then figure up the equation of lost fuel mileage, lol.
