I'm looking at a suspension upgrade for my 2010 BT50 dual cab. Doing the research and came across Sax suspension. Had a good talk to sales and they've got me convinced they're a good thing. Has anyone had any contact or heard feedback regarding this product? I'm keen to hear anything. Can't find much in the way of testimonials. I'm looking for a bit of flex and obviously a good reliable ride across rough conditions. I carry max of about 400kg of camping gear. Got a canopy and rear bar fitted also. I wonder if I'm just better off going for something cheaper because of the limitations of torsion/leaf? Set of leaf springs alone cost $1250. Appreciate any advice.
