JUST bought 2nd gen Rx350

Just got my first lexus, and coming from owning jeeps previously, im into offroad and overland builds. Being fully transparent its 70% looks; I don't hit the trail as much as i used to, but id love to replicate that overland SUV look. Im looking at wheel spacers and AT tires as a start for upgrades. Anything I should know before i start pouring money into this thing?
