I would drop one front and one rear shock from the Axle mounting point and let them extend fully, Jack the car up so as to let the
suspension hang at full drop.
Measure and make sure the Shocks have more than 30mm of travel left in them, look at the brake lines at the same time and see if another 30mm will max them out as
well.
Cheers.

have you already extended the brake lines, if not then yes you will need longer lines, (I am surprised that you have not had a problem already if they have not been changed).
Assuming new shocks went in with the 3" lift, shocks should be ok, when they fail, change them for longer ones!

Pretty arbitrary, but at 3" the lift is technically illegal (2" from NCOP). If you change it by going higher and need to get it passed you roadworthy requirements over the pits, then it may not comply at all (ie have to go back to 2" with no spacers.)
If it works and there is no real NEED to go higher and it is certified (engineered), then don't change anything.

Hey Wayne-o,
Have similar set up to what you described but would not recommend using the spacers unless the upper control arms have been changed in length to make the sping seats sit perfectly parallel to each other.
Would be cheaper to buy new springs (approx $200 a pair) than change those, have you considered larger tyres? they will increase diff clearance as
well as body`to ground height.
Oh and my existing brake lines have more than enough length so yours should too. (6 inch lift would need extended lines/aftermarket)
just a thought.

Tend to agree with Grandpa Jo.....
My GU (the 4.2, not the new 6.5 Chevissan) has Lovells 4" front and 5" rear springs. Recently fitted 30mm spacers to the driver's side, front and back, cos that side had sigged. The spacers made it sit just right again. I have not changed the brake lines and have had it up on a hoist so that the axles hang as low as they're ever going to, and there was still some "slack" in the lines.
I will be changing
the springs over to the Chev in due course and the old 4.2 will get the 2" lift that the Chev currently has. Note that some smart@rse put 6 or so tennis balls in the front coils of the Chev. They're all busted (of course)!!!

Whats the advantage of the coil spacers? Apart from raising vehicles centre of gravity?

majority of the driving here in the
Pilbara is rock driving, and it's not forgiving! although in other parts 30mm will make no difference, here it could be the difference between scrubbing the chasis rail or opening a door like a can of sardines! seen it happen plenty.
