I am using my car mainly as a cruiser and frankly the engine mounts are realy annoying me.

The car has these currently installed... (Pro-Flex)



I rang up about going back to Std but local parts guy warned against it as the car has around 420hp and says the std ones fall apart. Are they really that bad if you put new ones in?

I see other brands like Collins and Vibra Technics




Are they any better, worse than what I currently run?
