rough country BB lift problem

I just did the BB lift on my 2007 Grand cherokee hemi. what I noticed is the spindle hits the bottom of the coil ring at full droop, is this normal?

also, did anyone experience the upper and lower control arms want to stay centered? it's almost like the rubber bushings are keep them in place and you have to use ample force to raise or lower the control arms? weird

the reason they want to stay centered is becasue the engineers designed your !S43 suspension to be at the optimal level from the factory. Hence by raising the front coils via lift spacers, you are changing the goemetry of the independant suspension.. Plus since it is a 07 it is fairly new and the suspension will be tight from the get go...

Thank you for the reply
Ok, that explains why the A-arms are tight.
But 100 people have done this lift and no one has mentioned that the spindle hits the Coil at full droop
