High Performance Tranny Mount Bushings

Mazda's competition motor mounts, which provide a 40% increase in stiffness over stock, really should be considered first if shifter, and therefore engine+tranny movement is offensive. Next stiffer option are hockey pucks which are closer to 60% increase. Anything after that is really very stiff, and if your engine has any natural vibrations (such as rotors not within 10 grams of each other, flywheel or pressure plate not quite perfect etc), the vibrations can actually wear down the threads inside your front cover where the front mount bar bolts thread in to the aluminum.

If you prefer stock motor mounts, get yourself the RB torque brace.

Tranny mounts really should be considered as secondary to motor mounts, I think.
