Finally got around to installing a new 997 shifter ($250). This shifter isn't officially a "short shift" kit but the throws are about 25% less than the stock Boxster shifter.
My Boxster shifter has 210,000 miles on it (came with the blown engine chassis) and the bushings are so worn that the shifter just kind of flops around. This makes it hard sometimes to find the right gear on the racetrack.
Replacing the entire shifter and not having to mess with the bushings certainly saves time. And as you can see, my car doesn't have a center console so this job went really quick, like 45 mins (and I was definitely in no hurry).
The result is 150% improvement in shift quality! Not only are the throws a little bit shorter but the shifts are firm and crisp!
