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)

Here's a solidworks model to help identify the part I'm referring to.

I have been mulling this over for years as well, and only recently started collecting stuff to mess with it. Looking forward to seeing what you develop and your data (IMG:style_emoticons/default/smile.gif)

I should have a "proof of concept" part in hand sometime tomorrow.
If it functions as expected I'll make a full prototype right away.

My original idea centered around an add-on piece that clamped to the rod but I think the current direction is much more elegant and will provide really easy adjustment.

I had a Rennshift pop off at an autocross and it was tough getting it back in then tougher to line up. My fingers hurt after trying to get into the tunnel! Should be a good product!

Seems like a great idea!

However, couldnt the adjuster go on either end or even in the middle?
Wherever it is cheapest to reproduce the part with the mods I guess.

I am picturing a worm gear like a hose clamp with no slop and a locking screw of course.

So, you really think that you are smarter than the engineers that gave us an unsealed battery sitting over a crucial structural component of the car, yet under a hole that water can enter freely?

You truly believe that your ideas could be better than those that gave us foam in the rear quarter taillight area and trunk lid frame?

Of course those guys probably had two beers at every lunch, so you can't expect them to get everything right.

Looking forward to see how this works out.

I've had the benefit of 30 years experience with what they created, and more than a few deep contemplations on the various "mistakes" made by the factory. (IMG:style_emoticons/default/smoke.gif)
So if I actually do make an improvement that doesn't necessarily mean I'm smarter. (IMG:style_emoticons/default/shades.gif)

Oh, no. Here you are mistaken. Yes it fuching well will! A worm screw to angle the assembly. What could be more elegant? We might say out of kindness that the engineers thought of this and were told it was over budget. Or we might say something else. Well done!

It's possible that 30 years later, the local micro brew industry around your shop is better than the Stuttgart beer was back in the day.

A simple explanation.

If you are interested, I would be more than happy to give you my car to go from meh, to install all you bits for testing and trial....of course I would pay for the stuff....
