I have most of my Lift parts for my ZJ, I gathered Rusty's 3' front and rear springs, quick disconnects, sway bar drop and pay day I'm after shocks and a HD rear track bar and maybe the spacers. I was wondering if I did the Rusty's 2' coils spring spacer if that would be a bad idea along with the lift coil springs? like would it slip off or pop out or something. And other thing that I am not sure of is I am sure my stock brake lines will be OK with the 3in lift, but if i put the spacer on there it will make it around 5", will the brake lines be long enough to handle that? And with the lift, should I try to find longer bumpstops?
