Well, Sherwood developed his kit because Robotek (which used basically the same design, less the tabs, for more money) refused a request for a Rennlist (or predecessor) group purchase rate. His kit was (and still is?) unique in the tab parts his kit came with - I don't think any of the various other systems prevent the spring from loading the system unnecessarily when in 1st or 2d gear. I could be wrong about that, but the ones I have looked into don't deal with that issue, which leads to a whining noise when in those two gears, and wear - though possibly not significant - back in the gear box.

This harp spring system idea looks to me to be even better - genius, really. Fewer parts, no drilling of holes, the rubber boot fits, and - if you add a short shifter - no need to clearance the opening in the aluminum shift tower so the longer cross pin can move as needed.

If a guy can weld, it is easy to fabricate and add two tabs on the left side of the stock top plate, and to form and weld to the shift lever (carefully, as the lever's metal is kind of thin) a corresponding "hook" or whatnot tab mimicking the stock system on the right side of the mechanism. I did that with my Robotek (purchased before the Seine was available).

I suspect there is no money to be made selling just that part of the system. It also was just a bit awkward to attach, as the stock studs used to attach it were only marginally long enough.

The Robotek (which went out of business once the Seine appeared?) and Seine on my 915 transmissioned 911s ended issues with my or my wife's making money shifts. And eventually stopped my efforts to come up with a servo operated speed sensor input electronic progressive lockout system to make selecting too low a gear impossible. The marginal benefit no longer seemed worth the effort. The main wonder to me is why it took Porsche so long to come up with a shifter centering system which they instituted when - with the 994s? 996s?
