Make shifting MUCH quicker and virtually eliminate missed shifts.
Helps address missed shifts caused by poor shift detent "star" profile.

The Factory Pro Shift STAR kit is an awesome upgrade for the notchy shifting.
Installation: Slightly more complicated than replacing the clutch basket. It's right behind the clutch basket.
No case splitting required.
Shift Star kit worked awesome! Not one missed shift all weekend. Easier to find neutral, too - Which is good because I have to put it in neutral to start it for some reason. Doesn't like to start with the clutch in. With the close ratio tranny, I did a lot of shifting.

|The extension of the laboratory
for engines of the Swiss Federal Institute of Technology was completed
in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940).
He had a successful career in Berlin but returned to Switzerland after
the advent of the Nazis. His architectural style was somewhat similar
to that of Erich Mendelsohn. The staircase of the laboratory is in normal
use but well preserved.
