Didn't actually DO anything.
but found the RVD entry, so researching

Figured that 860mm OD tyres and a 1" spacer lift juuust fits under the NCOP 1905mm total height (stock +50mm combined).
Disclaimer: May have/fit more than 1", but dropping to that will clear any stickers and still be drivable. and not look as funny as a Long-Arm TJ on 28s! (Hi Ken!)
