iv seen 3 inch springs what would i need todo to front to match this height in rear please

Aftermarket upper control arms, shocks, modified steering and torsion bars wound up.

if you stuck 3" lift springs in the front there wouldn't be any down travel left so it would be pretty hard to keep both front wheels on the ground at the same time

Not worth doing the 3 inch lift even though calmini do a 3 inch lift kit as you wont have any strength in the steering.

use the search function here and look for terrano build threads so you can see what is involved even before getting to the actual lift.
