The best kit for the Vitara is the Old Man Emu (OME) kit from ARB as it has the longer front struts. This gives about a 30mm lift. to go a bit higher, you can use Grand Vitara front springs from OME (sorry I've fogotten the part number). These are for a heavier load and make it sit up a bit higher to get your 2" lift. to get 2" at the rear, you'd go with longer springs (or spring spacers) and Rancho longer shocks.
When getting extra lift, a lot of people do a simple modification to flip the strut mount so it points down which makes the top of the strut 30 mm or so lower to give more down travel as with standard struts there is some unused travel. To do this mod, you remove the 3 bolts holding the strut mount on, remove the top bolt on the strut, take the mount out and place a socket over the welded in studs and press them out. Clean up the hole with a drill and get some 35mm HT Grade 8.8 bolts and nyloc nuts. Flip the mount over and bolt it all back together.
The Vitara is dead easy to fit a suspension kit, spring compressors are not required.
You can also do a body lift on these cars. A Guy by the name of Just Cruizin on outer limits sells an excellent kit which I fitted. Helps to get the sills up out of harms way and fit bigger tyres.
This is my Vitara in it's prime with OME suspension, the 2" body lift and small 29" Super Swampers. We were pretty sure we would have been able to fit 31" tyres with this level of lift but the Swampers were the right price.
Hope this helps. I am a bit rusty on the Suzi. check out the Outer Limits Suzi forum, AusZookers or the North Brisbane Suzuki club forums which are the bibles you nee dto know. Also a lot on the US forums too.
If you want to do something on the real cheap, flip the strut mount and get some spring spacers from Bruce on Auszookers, but make sure you still have enough strut/shock travel.
