Are your rear spacers on top or bottom of rear spring? I installed a 3.5 front and 2.5 rear and it feels like it real sensitive driving now. The kit says to put on top but the pic shows it on the bottom so that's where I put I'm confused now. I even got it aligned too same issue. Any help would be great.You can get your fronts up to 39" but much more than that would be way cranked on the keys. I have a 2" rear spacer and 33s sitting at 40.5 rear and 39.5 front. What tire size do you have?
