Help on lifting my truck-the cheap way!

[gunnym4]

bros,
i'm back again-hope you guys bear w/ me...
need help w/ my nissan 4X4 Pick-up Truck w/c runs on geolander 31x10.5r15 tires & used around the metro only...

I want to Add (a little) More Lift to the Front Supsension to eliminate the tire rubbing everytime i do tight turns & also, to make the front levelled w/ the rear suspension as well....
What else can be done & Where's the cheapest place to have it done?

Background:
had the torsion bar cranked to the max already by my friendly talyer but it seems they ran out of ideas on lifting....& ever since then i notice a change on the Front Camber settings to Negative (very slightly) just by visual inspection...

Do i have to have it adjusted to Positive camber? even if i use it in the metro only?

Pls. Note i operate on a Tight Budget...Many thanks & Merry x-mas to all!!!
