Front and rear adjustable panhard rods
Caster correction of choice; plates, drop boxes or arms
Longer brake lines from each diff to chassis, or at the very least fit rear to front and get new rear one
Swap rear tail shaft end for end
Cut 15mm off rear off rear diff plate that contacts bump stops
Would be nice;
Longer rear lower arms
Heavy duty adjustable drag link so you can get steering wheel straight
Heavy duty track rod
Better steering damper
Strengthen rear top coil perches
Modify gearbox crossmember to clear front prop shaft
If I've forgotten anything I'm sure someone will say so.
I've just done a 3", could I get some more specifics on these two points please.
How does the tail shaft change for the better by turning it?
How do you cut 15mm off the steel plate? Do you need to increase the bump stop distance for more flex? I've flexed mine up with the fork lift and I can't get it to hit the rear bump stops which already have a block added on top of the plates.
Sorry I worded that badly, the plates on the rear diff that hit the bumpstops, cut 15mm off the back of them to stop them from being able to damage the bottom of your shocks on full down travel. I wasn't referring to the height of them, it's the length, if that makes sense.
And as explained above regarding the rear tail shaft.
Because of the geometries of five links just be aware that you will have different clearances at full down travel on each side, which is different again to lifting a car on two post hoist and having both sides full droop at the same time.
Depending on how fat shock is and how long your lower control arms are will determine if the bump stop plate needs to be cut.
