Short Shifters...is this true?

**I think it might make sense, that if the throw is much shorter, and you do ride your hand on the shifter, that the same amount of pressure in one direction with the SS would be, eh 40-50% more than on the OEM shifter?

You've got it backwards, a short shifter is harder to shift. So it requires an imput of more force to do the same work as the stock shifter. Therefore if does not magnify the force that is input as much as the stock one.

Think of it thins way, if you were trying to pry something up, which would apply more force, a long screwdriver,, or a short one?

I said the same thing to the tech when my P5 was in for service and, after a short road test, he had mentioned the warranty could be voided if I did not remove the B&M :bs:

wrong,
look at several aftermarket short shifters its the part thats after the ball the matter the bottom half you want this longer for a shorter throw, so what you just said makes no sense basically your saying that your idea of a short shifter is the lower it is for the driver adn thats just not the trueth, the driver can hav ea shifter from the console out the windows and still be a short throw shifter becuz of whats after the ball man.

What in the world do you mean? My intervention made sense, it's the tech that was way off... I may not be 100% bilingual my friend, but your written english sucks.
 
The ideal short shift kit has a short upper half and a long lower half...That is the combo that will produce the least amount of travel by your hand. However, lenthening the lower part of the shaft screws with the internals of the transmission...I'm not an expert about that so correct me if I'm wrong.

...here's what happens in basic physics. We'll asume that the lower part of the arm is equal. When the upper length of the rod is shorter, the amount of torqe (produced by your arm) required to move it is greater. Its just like a car jack. Its easy to lift the car when using the far end of the jack, but try pushing down from half way and see how tough it is.

Even though the short shifter requires more torque from you, the force on the other side of the ball is equal to a long shaft except for one thing...MOMENTUM. When you have to push the shifter hard, you are more likely to slam it into its farthest position. Its this slamming that can wear out the forks on your transmission. With a standard shifter you (well at least I) are just guiding the stick into the right position and letting it stop where it wants to almost effortlessly.

If you get used to the travel length of a short shifter it won't be so much of a problem...in fact I doubt it has ever cause a problem that didn't already exist from the driver's shifting style. But if you are acustomed to moving the shifter hard, then a short shifter will aggrevate the situation. A tip is to never grab ahold of it. use the palm of your hand with your fingers relaxed and you'll be ok.

Agreed....It is more driver error/abuse that kills transmissions and drivetrain components. This is why I will match revs and double-clutch from time to time. It helps take some of the shock off of the drivetrain. Like mentioned in an earlier post, double-clutching and rev matching are becoming a lost art.
 
I always rev match...a way to know if you're doing it or not is to watch your passengers...do they jerk back and forth when you shift? Do you get a second whiplash from the drive train after you let out the clutch? Driving a standard can be almost as smooth as an automatic during normal driving conditions.

as far as dbl clutching goes, I try it every once in a while but my feet are too big. I have to be either braking fairly hard or not braking at all (in which case I just tap the gas with my foot and let it coast to the right rpms before I let out the clutch.

Usually I just wait till the car slows down to just above the idle speed for a particular gear before letting the clutch out. In heavy traffic this works fine cause I don't need the high rpm power to accelerate, I just want to keep the car rolling at idle.

you're thinking of heel-toe as double clutching. double clutching is just letting the clutch out while in neutral, between gears, right? but i thought this wasn't necesary or even beneficial for newer cars, since we have synchronized trannies?

30 minutes of spell checking for 4 lines of text!!! Have a good life.

End of subject.
 
I spell check as I type...if something comes out wrong, I hit the delete key and fix it.

At least you aren't typing in ALL CAPS...that's a sure sign of someone who doesn't look at the screen when they type.

I think we should bring the level of this forum past the 3rd grade...anyone hear of proof reading?

With that grammar he needs 30 minutes.
