I just did this combination on the F8X and there is some slight vibration at VERY slow speeds at start-up (1-2 mph) but goes away completely once you are on the road.

The inserts should add durability to the stock mounts since it will reduce movement overall.

I would not go with anything harsher/harder for motor mounts since they will rattle your brain out if you go with something harder than stock.
They are rated similar to factory in terms of hardness and vibrational properties unless I go full race. I just like the way they’re designed. Rev Shift has an offering too but I don’t like the black + green. They also offer stiffer or same as stock (hardness/vibration) but made from polyurethane vs rubber for longevity. I’d rather not get inserts since mine are just worn out.
