Nice pics and a very nice car. But man, there is no way in hell I would mess with that TSX shifter. Stock, it's as close to perfect as it gets, IMHO.

Have you tried a shortened-throw version of the TSX shifter? Still smooth as butter. 
No, I haven't. I'm just not convinced that shorter always means better. Your kit shortened the throws by 37% and presumably you find this "better". Would it be better yet if it had shortened them by 50%? By 60%? At some point shorter is just shorter and that's all. I'm glad you like your modified shifter and that the great shift feel is retained.
For me, when an aspect of the car is already at or near best in class my inclination would be to leave well enough alone. Change for the sake of change or for "modding" bragging rights is just not for me.
Now, the shift feel on my '07 Altima is something that COULD use improvement, so I will be keeping an eye out for what becomes available down the road.
The TSX is a great car and one that I seriously considered buying. Enjoy.
