BUT YOU CANNOT FIND THEM ANYMORE. A TYPICAL PLASTIC 75A4 TUNING KNOB WEIGHS ABOUT 3 OUNCES.
THIS WEIGHTED ONE COMES IN AT ABOUT ONE POUND -- IT'S A MONSTER! MACHINED NICELY AND WITH A NICE POLISHED FINISH.
I DON'T HAVE THE SPECIFIC MACHINING PROCESSES USED, BUT IT IS WELL DONE. IT WILL MAKE TUNING YOUR A4 SO MUCH SMOOTHER THAN THE ORIGINAL LIGHT PLASTIC KNOB. YOU MUST HAVE THE 4:1 ASSEMBLY/KNOB NOW TO "UNDO" THE OLD KNOB AND REPLACE IT WITH THIS ONE.IN OTHER WORDS, THIS DOES NOT INCLUDE THE "MECHANICAL" ASSEMBLY. INCLUDES THE KNOB, THE SPINNER, AND THE BOLT TO SECURE THE SPINNER.
