Re: Fw: <E36> Lets compare bending the selector rod to the ERK - again...

[BenLiaw@xxxxxxx]

ron, rob, others;

actually, if you think about it logically, the lever you are using (M
Roadster) is exactly the same in both tests (with and without ERK).  the
dimension of the upper portion of the lever (above the ball) does not change
physically...it remains the same.  it would make sense that it takes the same
amount of force to move the same distance, right?

a better device for reducing the "force" of the shift (from 8.5/9.5 pounds to
some number lower) would be lengthening the upper portion of the lever
(something a ti owner like scott and others don't like).  with the extra
length, the "force" to move the shifter will decrease with more and more
length you add.

the ERK was really designed to address the "notchiness" of the shift, which i
would imagine is a more a "driver" preferrence.  ron originally bent his
selector rod, since he did not like a perceived "increase" in notchiness.  the
ERK moves the selector rod in line, to reduce any additional notchiness.

i've learn that severely increased angles on the selector rod will wear out
the input shaft seals of the transmission, talking from other short shifter
companies in the recent past.  from a conscience frame of mind, i can only
recommend some sort of solution that straightens out the selector rod as close
to, or better than, stock.

perhaps a better measurement of "notchiness" is actually comparing the
following: 3rd to 4th and watching the "spikes" in increased forced used.
this would probaby more accurately depict "notchiness" vs. "force" used with
and with the ERK.
