Got my Cobb Short Shifter installed tonight. Installation went smoothly, and more quickly than I expected considering it was my first time disassembling the storage cubby and trim around the shifter (although I did disassemble the center console when replacing my head unit, so I had that much experience).
I didn't replace any bushings, and suspect that I'll be happy enough with this configuration to not bother.
I have the shifting throw as short as I could make it without cutting/bending the front-left corner of the metal plate. I have the height set a bit shorter than stock, but not WAY shorter than stock.
Looking forward to getting used to the car with this and also my new 19mm RSB mods!
