Weltmeister Short ShifterHave you noticed that reach to fourth gear is a bit long? I actually have to lean forward a bit to reach the shift knob for that gear. Porsche and other vendors have addressed this problem with short shifter kits.
The tube that comes out of the transmission must be rotated and slid forward and aft to access the various gears. This action is managed at the shift lever with two pivot points, the center one at the top of the housing and a second ball joint at the end of the shifter. Mechanical advantage of the shift lever is provided by the ratio of the lengths of the arm on each end from the center pivot. Change the position of the center pivot point and you can decrease the mechanical advantage which will make the motion shorter but the force required will increase.
Porsche short shifter kits are still available for later years but not for my car. The Weltmeister short shifter is designed to fit on 1970-72 914 and 1965-72 911/912. It increases the distance from the center pivot and the lower ball joint. They supply an aluminum adapter plate that mounts between the the shifter housing and the tunnel to fill the increased length.
There are three problems with this system.
The initial test drive after the change are very satisfactory. The shift positions are much more positive, and as expected the throws not nearly so long. My solution makes the shift lever about an inch longer than Weltmeister intended. This is an improvement. Without the extension it is a bit short.
And after a couple of days:
Snick, Snick. The new shifter goes snick. I did not expect such a dramatic difference in gear changing as created by the new short shifter. If you have not done this to your old 911/912, do it. Clearly more has changed than the ratio of the two levers around the center pivot point. The tolerances are much tighter leading to a feeling that the shift lever is actually attached to the transmission. No longer will I complain about vague shifting - it does not have to be that way.
From Wonder Wand to Weltmeister. Recommended.
For some, the Weltmeister short shifter is too short.
