keeping my 7/100,000 warrenty intact

just got a 2002 TJ Sahara for the wife and she wants 33's on there. What can I do that will not void my factory warrenty? I was thinking 1" body, shackle, and then a 2-3" suspension lift. What engine mods can be made without voiding as well? Current plans involve headers, MSD ignition system, and cat back exhaust.



Thanks,
