Unfortunately, you'd likely have an issue with the UCA as well, if you're planning on using the coilovers with your lift kit's strut spacers. The problem is that the strut spacer moves the upper mount for the coilover down, and since the upper coilover mount protrudes out more than stock, it causes serious fitment issues with the UCAs larger tubular arms. Your best bet for a performance improvement without fitment problems is to get the coilovers on their own and then also grab a pair of BDS's Fox 2.0 Shock for a 6" Lift Kit.
