Outer Limits 4x4 Board

Hi all.
Im from SA. Here where we know how to braai. Haha.

i have been reading a lot in the last few years about the paj mods and and...
A few things i need confidence on is all the in and outs of fitting 33 on my nj.
Will the factory lift and gq coils be enough to fit 33" ? I do have coil over shocks in front, and will also be fitting a ball joint flip with 25 mm spacers and high tensile steel bolts. Also will i be able to keep the stock
wheels with the 33x12.5x15. My reason is simple. I would like the ground clearance without moving centre of gravity to the top by means of the body lift?! If that makes sence.
Also how much of a change would i notice in low range.

Any and all inputs would be appreciated.
Thanks.

Ok so i went ahead and fitted 33×12.5 × 15 Cooper stt on my standard wheels and all is fine, even without the gq coils. But i will be fitting them coils anyhow.
