What is the best option for stopping engine shuttering? Mine has gotten quite a bit worse with a light aluminum flywheel and race pressure plate. Is the racing beat engine torque brace the right option or is using competition motor and transmission mounts the way to go?

 

I would think that any brace or solid mounts would make it more pronounced.

 

+1

 

From the Racing Beat website:

"The Racing Beat-designed Engine Torque Brace for the 1979-85 RX-7 substantially reduces or eliminates the shuddering experienced by many RX-7 owners when engaging the clutch in either first or reverse rear"

I would also think the stiffer mounts would reduce shuttering because they don't allow as much movement

 

Solid mounts make it more rigid,They also don't absorb any of the vibrations

 

Yes.
