A heavier shift knob puts the weight towards the end of the shift lever.
This increased momentum while shifting gives you a greater mechanical advantage, allowing for a much more positive feeling throw when rowing through the gears.
Knob feels great and has a sleek look to it. Weighting feels good around the top and construction is solid. There was no issues with stitching or general make of the item however during installation the bottom part of the leather-type material actually tore due to friction from the shifter boot, a little disappointing but nothing I can't fix.
