>Better, yes and no. Just like the kirks you'll get a lot of vibration until they break in but IMO these will vibrate more because there is no soft rubber to absorb anything. And in that regard they'll hold the motor in place a little better with very little movement.
Easier to install, yes and no. Either way you have to remove the mounts, with the kirks, just add, with SS you have to cut/remove all the rubber and ring. Both stick out past the mount so putting them in isn't bad but not as simple as without.
I've have kirks and like them. Stiffer than stock and work.
I've installed the SS on someone else's mounts (MR2 w/3rd gen swap) and I don't know first hand how they are compared.
As I stated before the kirk mounts are softer than the full poly mounts. It's better for comfort that way, but not as good for performance. In a FWD application it's much more vital to keep the wheels on the ground, which means as little engine movement as possible. However there's a threshold to how much NVH each individual can stand. I installed the kirk front and rear in my previous Celica, and it was just fine for me, but there was room for improvement since the engine moved anyways, just not as much as before. However everything rattled much more than before, and compared to the performance I felt it wasn't worth it.
This time I think I'm trying the full poly inserts and see how it goes. MR2 is different from the Celica and the NVH transmission isn't the same as the chassis isn't the same. The Celica's cabin is a bit more insulated from the engine than the MR2's, and that makes a difference (I've driven MR2s with Kirk inserts and it was much worse than my 5G with kirk inserts. Both were 5SFE)
