I'm in sunny Central Florida, where most of the back roads are all sand, with a few rocks thrown in by Mother Nature, just for fun.
One big problem on the SX4 is the rear differential. It's an aluminum casting and very easy to damage, so since I do love to go were others fear to tread, I got a Skid Plate for my rear differential. I also cut a nice round hole in the back of it, to facilitate easier differential oil changes.
With the addition of this Skid Plate, my delicate rear differential was protected.
I found that rather than buy expensive tires to go off-road, I just dropped my tire pressure, on all four tires, down to about 20psi and I could go places where Jeeps feared to tread. lol In the four years that I had my SX4, I never did get stuck.
Then, just In case I did need to be pulled or to pull someone else, I added these heavy duty Tow Hooks to the front of my SX4 and I had a trailer hitch on the back in place of the stock tow loop, which I broke off, pulling a big car out of a sand pit.
I have a friend who lives in Au and is a member of a 4x4 club that takes trips through the outback every year. From what I've seen of the pictures he's sent me, that's no place for a little SX4.
I had a lot of fun with my SX4, but had to unload her when Suzuki USA closed up shop.
I hope they are still open for business in the AU.
