Great mounts, lots of vibration
Make sure to get the OEM motor mount brackets. Lots of noise and vibration, would try a putting a rubber pad no greater than an eighth of an inch like the kind you’d put on a skateboard to raise the trucks and dampen landings between the mounts, engine and brackets, if I was committed to using them. The mounts in combination with the Kein pitch stop, though any stiffer pitch stop than OEM would do, helped provide a noticeable decrease in slop while accelerating.
