Also, you are DEFINATELY correct that short shift kits increase transmission wear. For the same hand speed, the short shift kit causes the trans to shift faster. Faster shifing leads to faster wear.
Its simple physics that can't be denied.
NOW, the question is "how *much* more"? On that, I am not sure. But, given the extreme amount that most SS kits give, I'd say it is not insubstantial. My cars will always retain the factory shifters. Remember, it doesn't cost more to make a short shifter, if the factory thought it was better, they would have simply done it.
I thought it was bogus too but at least he mentioned his affiliation in the article. I've driven a car with the UUC in it and it feels pretty good however I don't know squat about short shifters. I know some people who do know more about it than I do but unfortunately not about the UUC. I have heard an earfull about the others. Lots of comments about poor workmanship, sizing, et cetera.
It's been said that many of the short shifter kits tend to create a premature ending to one's transmission. The shifter is faster than God, whoops, BMW intended and crunches through important things like synchros... I'll shut up now, I don't know what I'm talking about. However, I have seen a tranny pulled apart and all the "nice" chew marks on the synchros from the short shift kits. Damn things sheer off whole bits at a time.
'87 535is - no short shift, same 'ol sloppy shifter. New bushings didn't do much.
'89 325is - perfect unadulturated garage queen
