mate, the photos and the tyres look great! Vehicle is same colour as mine.
Can I point out some experiences I have had after some 80,000 Km plus with a suspension upgrade.
You talk about wanting to drive it offroad - do half the job and you'll have to re-do it!
Spacers will not alter your vehicle's capacity to do offroad work BUT it will make your vehicle unstable due to the fact that you have lifted it.
A 50mm ARB medium duty lift kit will firm up your suspension, give you great control and stability on the highway, better cornering, no wallowing.
It will also give you great offroad capacity i.e. extra ground clearance, control over corrugated roads at 80 Km/h, safe driving conditions and ability to carry extra load (I notice you have a roof box)
When you go down that track get the "Sport" version fitted, CRDSTU has a post here somewhere on ARB lift kits.
In my case I tow a 2.5 Tonne (loaded) caravan and I found the medium duty too light and replaced the rears with the "heavy duty" springs and polyairbags.
A suspension lift will stop your vehicle sagging in the rear as it is in the photos, you'll feel like you have a brand new vehicle.
The difference in mine was amazing - I had my system fitted at 10,000 Km on the odometer at a time when I was driving down the western freeway every day.
Sorry if i've been blunt and to the point,
I hope it helps you!
