I installed this piece on my '07. The throw is very short compared to stock. It's very notchy, but with normal shifting it's not hard to shift...it's just very "mechanical." Very easy to drive/shift under normal conditions.
If I have the "need" to shift quickly, I find that I'm slower than with the stock shifter. Not terribly slow, but it takes a little more effort to get in the gate when you are shifting under "duress"...aka, racing.
Shifting into 3rd (for me) is definitely slower, again, the notchiness of it.
At times there is a slight "buzz" that can be heard...I think it's where the stick and ball meet (inside the ball?...as the lock nut is tight). It doesn't happen all the time, relatively rare, actually. But it happens. Same can be said for many aftermarket shifters as they all pretty much use poly bushings instead of rubber. Thus, more vibration is transferred through the linkage.
So, to sum things up:
1. It looks great.
2. Around town driving is a breeze and pleasant to row gears.
3. If you're a balls-out racer, you may not like it.
4. Occasional mild buzzing sound.
Hope this helps.
