With all the enhancements available for our shift linkage, there's still one thing no one has ever addressed.
Adjusting the rotation so all three shift planes are where they belong relative to the lever assembly has always been a PITA, and is even more difficult with a Rennshift due to the small opening to access the pinch bolt.
In addition, installing a more precise shift linkage assembly, like we all crave, makes precise adjustment even more critical.

There should be a way to maintain alignment of the tunnel rod with the fork under the shift lever, and make precisely controlled rotation adjustments in a minute or less.
An idea I've had on the back burner for a long time has finally reached the prototyping stage. (IMG:style_emoticons/default/idea.gif)

I'm going to test a replacement Fork piece (914 424 171 01) machined from billet that incorporates a worm type adjuster against the splines of the tunnel rod.
If it works it I believe it will be a game changer. (IMG:style_emoticons/default/smilie_pokal.gif) (IMG:style_emoticons/default/smoke.gif)
