How is resting a 10lb arm on your shifter even gonna compare to having a 170lb individual in your car with you? I mean any extra weight in your car is ultimately added to the gears pulling the car. Thats all speculation but thats how I see it.

I should have waited until I installed the Z4 shifter and ZHP knob to see how it feels before I installed the weight to the selector rod, but as you may know from my other posts my car is out of commission until my new subframe bushings get here so I am trying to get as much 'other' stuff done on the car as possible in the mean time.
The ball joint of the shifter arm will support the vertical force of your hand resting on the shifter. It will not support the torque that the force of your hand creates. There will be some pressure applied to the gear shift mechanism by resting your hand on the knob. Again, I can't see how this would be much of a problem. The shifter does not control how the gears actually mesh into each other (that is set). It merely selects which gears are actively transmitting torque from the crankshaft/input shaft.
