The Mountune quick shift plate is a pain to install, but WELL worth it, being the most throw reducing option on the market!
I was going to do the boomba interior shift lever as well, but decided against it with the installation hassles (everyone breaking the thin plastic clips/pieces during install), and the lack of need for the throw to be any shorter for me, as well as the fear (very 'unfounded', I am told
) that there would be major cable bind with everything maxed out to the shortest throw possible.
I did do the under hood cable bracket bushings (also a pain, but also
maybe 'worth it'), but did not do the interior, under the shifter bushings, since I did not want to mess with that if I was not already doing the lever itself.
