Body lift is also not as straight forward as you may think. You have airbags in your GV and I think for cert you need to prove it doesn't interfere with the airbag operation.
I have an 02 Suzuki the same, It's had an Old Man Emu lift kit in it for about 35,000 km and 5 years. Only has a quoted 1.25" lift. The offroad tyres I run on that measure about 29.5". I can't fault the suspension kit but do shop around and do some research as OME is probably the most expensive option.
You'll probably find if you flex the rear up it'll hit the inside of the guards as well.
A few other GV things for the 1.6 model
-coby extractors and replacing the cat with a resonator really wakes it up.
-you can get a Gibson Airflow snorkel to fit (as long as you don't have ABS) - although I've had mine 4-5 years and have never seen another one.
-If you have trouble with the air actuator that engages the front diff, you can get a 5.125 diff center out of a older vitara and as long as it has the correct size side gears, it'll bolt straight in- I have done this mod.
Here's a pic of mine, the dents are from when it went on its side at Rallywoods a few years ago.
