Readylift SST, Does anyone have pics of this lift on their truck ?

So my coworker just got the Readylift sst kit 3/2 done about two weekends ago on her 2012 Tacoma dcsb 2wd (base model I think) and after driving it around she is experiencing vibrations when coming to a stop, very noticeable to where feels like the front of the cab is shaking. The installer told her she did not need the diff drop spacers because it is a 2wd so they only put on the sway bar drop spacers.

Anyone else running this kit and having this issue? Does she need to install a CB drop bracket? I told her to get her brakes checked to make sure there is no warping of the rotors and her brake pads are wearing evenly. Also to make sure the calipers are tightened down good.
