Pinion angle Is something you need to look at now that your lowered. Could possibly explain your "bump". I'm still new to the 3 link suspension on these cars so I'm not sure if you need an adjustable UCA or if a non adjustable will work. I do know that one of the bolts on the UCA mount needs up torque to something like 300ft.lb.... I have some nice tools and some real nice torque wrenches but I don't have one that go's over 250, I was thinking that I would either get a shop to put it in or just have them torque that bolt to 300 after I get it to 250. Also, don't reuse that bolt, you will need to replace it.
