3" ome lift kit

Hey everyone, im planning on putting an ome 3" kit on my 2005 double cab. Im just wondering if anyones put these kits on and what I should be buying. I do a bit of offroading but mainly street driving. I have heard nothing but good things about the OME lift so that's why Im going with it. So far I have like 885 coils and shocks for the front, the trim packer kit, new u bolts and the Dakar leaf pack for the rear. Im wondering if I should be doing new UCA's also or If my exisiting UCA's will be okay. I have an airbag kit in the back of my truck also that I plan to keep. Does anyone know if I put this lift in id be able to run 1.25" spacers to my 17" fuel wheels and 285/65/r17 nitto terra grapplers? I just want a bit more stance than my truck has now, using the wheel spacers but I don't want the tires to rub. If anyone has any input, its much appreciated! thanks guys
