I have the VT HON200 as well. They are significantly stiffer than stock, but softer than most aftermarket options. The increased vibration will cause more things to break as @spectacle mentioned above; poorly fabricated welds will crack, etc. Positive side is the motor mounts will no longer tear and leak, increase responsiveness, etc. All in all, they're good mounts for the street/track. I wish somebody made a "larger" oem style mount for our cars; something with the same properties as stock but more robust to resist tearing

 

i used blox motor mount rings. deffinatly stiffer but im not rattling fillings out my teeth either
