hi there, just got my first 4x4 and i know almost nowt, could someone give me an idea of how to lift my sporty by a couple of inches? i have heard longer shocks would do it, others however say major surgery is needed to give it a "body"lift, is there a happy medium? any help would be greatly apreciated...also, what is the biggest (most practical) tyre i can put on a standard 15" rim?
