Well, after installing my Belltech TBSS stock height kit my alignment shop says they can't get it lined up correctly. My Envoy measures about 32" on all 4 corners from ground to edge of fender, give or take an 1/8". The shop says there's no more adjustment left and the camber and caster is not achievable to get within spec. All the reading I've done on this I thought for sure I wasn't going too low to need the modified UCA's. Please take a look at the readout they gave me and let me know what ya think. I replaced the struts, springs (SS stock) outer tie rods, sway bar bushings and links. I did not replace the LCA, UCA or ball joints as they all felt tight and the shop verified that they are all tight and don't need replaced.
