Don't forget, the 3rd generation Vitara/Tracker has a rack&pinion steering linkage. A body lift will interfere with the length of the steering linkage. Refer to the message of the Vitara finally lifted. Had to get a machine shop to correct the steering linkage.
I'm trying to get comfirmation from Overland Components in the UK on their body lift. Calmini is juggling with the idea of mass producing one. And I'm looking at just getting a simple 1" spacer to work.
