Some go longer and do ok but your experience not uncommon.Changed motor and transmission mounts, with only 40k on this set. I didn't expect them to be this bad, but dang the car drives a lot better now with the engine connected to it. Went with stock mounts but I'm wishing I went with solid rubber ones.
I'm running poly mounts. They took some getting used to and have broken in over time - but they give the car a little more visceral feel - transmitting a faint vibration at idle to the cabin.
