I have a 1998 Taco Ext. Cab V-6 TRD Manual. Right now i have the OME 881 coils up front. My question is, if the OME coil gives 1.75" lift, can i add a 1.5" spacer on top of that, to make 3.25" of lift in the front with a diff drop? I have the ADD, will this much lift in the front be too much, i heard you can only have 2" lift with the ADD but revtek and others have a 3" lift for these same tacomas. What kind of problems will i run into if i do this?
