Your stock mount looked like it was in PERFECT condition - you didn't need a new one.
All joking aside, my mount was the same way before I swapped in AWR mounts.
Durometer on those? How's the vibration?
Durometer i believe is somewhere between 65A and 70A.......Vibrations are 10x less then vibrations from the AWR front mm I used to have....but thats my opinion lol everyone has their own vibration tolerances
