Dreamliner is right about lowering it too far. XI's have less spring travel than RWD E46 cars, so your problem is compounded.
Almost any coilover setup offers difference coil spring rates up to 8 or 9Kg/mm. So you can go into the dirt with almost any coilover setup if that is your preference. But you will pay for the drop with a crappy ride, and poor handling. If that is OK with you, then go for it.
BTW ditch the green wheels, it looks like a carnival ride.
