I have my CTS motor mounts installed 2 months ago, along with my 034 control arms kit. I could of order the 034 motor mounts with my 034 control arms kit but the 034 motor mount cost 50$ more per mount. So I decide to save 100$ and go with the CTS. So far, really happy, the car feel more stiff, shifts are much more direct and no extra vibration compared to stock mounts.
