i have one. it doesnt really shorten the throw, just the actual height. also its an akward location for the shift knob, unless you use something as a spacer, or a mazdaspeed knob, youll end up with about 2-3 in of empty space between the boot and the knob
As Liquid said, it doesn't change the angle your shifter sits at, but it does effectively shorten the throw some just due to the shorter length.
If you want a really short throw then get an aftermarket one, but I tried a TWM first gen one before and didn't like it. The TWM was stiff as hell for some reason and the short throw reduced the feel of the shifts a lot.
the B&M is my favorite
That's your opinion. By all means you have that right... My shifter is the best bang for your buck. These shifters are made from the highest quality aluminum and hardened steel, the shorter the throw the quicker you go!
Of course it is, B&M did the R&D for you.
But, but, but my shifter is better
