Outer Limits 4x4 Board

G'day, just after some informed opinions on what would be a good suspension set for a 91 terrano? Is it worth bothering with a BL or is about 1 -2" avail from a stock standard upgrade?
Currently running 31 x 10.5's with slight rubbing, also got a winch and bar on front.
Any assistance greatly appreciated. Cheers Bairdy.
