Does anybody know if a knob for a WRX STI will work for the FiST? After very brief research it looks like they both have M12x1.25 thread pitch and both have the reverse lockout. Therefore they should be interchangeable? Is the reverse lockout the same size and height? Does anyone have an STI friend that could test this theory out for me?? This would seriously open up our options for aftermarket shift knobs. I love the stock one but its good to have options.
