The Z06 uses a very similar rubber based hydraulic engine mount used on the CTS-V. Here is the Z06 stock engine mount. Look familiar?
Here is a YouTube video on the undercar with stock and aftermarket engine mounts (Pfadt Engineering - makes a lot of Corvette items). The brand does not matter and the concept is identical to our cars. Under load, the engine and powertrain movement is enough to cause issues downstream on the powertrain. The engine movement is not simply side to side, but front the back, as well, which can increase pinion loads and drivetrain thrash.
I really noticed the difference when I switched out the motor mounts on mine to the ones 2003RC1 built (the black ones). Easier to shift, no odd driveline clunks at low speeds, awesome downshifts and less drama when the wheels do hop a little. Sure, there is certainly extra vibration, which was a big shock at first compared to the stock ones, but, over time, you really start liking the feel. I feel more plugged into what the car is doing since it feels less rubbery and it's kinda cool.
