Frontera suspension lift

G'day all,
lots of people have different opinions regarding winding up the torsion bars on 4wd's.

What I'm interested is experience of people who have wound up the front of their STANDARD fronteras - mine is a 2001 V6SE and I want to lift it a little bit.

Who has wound theirs up, how far, and to what affect. I want to know if I'll brake something or loose too much droop if I do it.

My old man tells me he wound up the front of his old rodeo and used it for years with no problem.

I want to know if I should invest in a set of RockCrawlers or something for the front if I do this.

Next the rear - what are my options and roughly what cost. I'm not so stressed about the rear, but obviously a little lift here would be good with that bloody low fuel tank. I doubt I'll go to oversize rubber as cost etc probably isn't worth it for the amount of off road it will do - plus as it does roughly 70% on road tyre wear of decent off road rubber will be too high and cost way too much. So will probably stay with standard tyre sizes but shift to coopers or bf goodridges.

cheers and thanks for your help
