Re: Lets compare selector rod pin deltas with & without the ERK **Rob

Hi Ron,

    Thank you very much for providing such excellent, detailed information.

    However, I would like to clarify two things which are a source of
confusion regarding the ERK and are not clarified by your post:

1) The ERK is *only* designed for M-Roadster or UUC Motorwerks Level 3 (M3
Level 2) shifters.  We do not recommend the ERK with any other shifters, we
do not sell it for any other shifters, we say "use the ERK only with Level
3/M-Roadster shifters."  The ERK is not designed to be used with other
shifters at all.  In your post, you show that you have tested the ERK with
other shifters and provide that data table... the numbers that look better
than stock are only with the M-Roadster shifter.   Showing the data with
non-recommended parts combinations infers that UUC Motorwerks recommends the
ERK with those shifters - we do not.  It is damaging to UUC Motorwerks'
reputation of producing properly engineered parts to suggest that we
recommend such obvious mismatches.

2) In your post, you said "the disadvantage of the ERK with the Z3-M shift
lever is... the fact that it raises the shift lever ~one inch compared to
non-ERK."  This is not accurate in terms of the total upgrade.  I hear that
question about height from people considering an ERK, and your post further
confused the issue... the M-Roadster/Level 3 lever is 20mm shorter than a
stock lever from any E36 3-series.  The ERK raises the lever 25mm, bringing
the entire shifter assembly to just 5mm higher than the stock lever.  This
is nowhere near one inch and is hardly noticeable.  Again, that kind of
confusing information affects the enthusiast's perceptions and ultimate
decision.

    There is an all-new (as of this morning) shockwave Shifter demo on the
web site graphically illustrating the difference in shifter throw, selector
rod angles, and shifter height between a stock lever, a Level 3 lever, and a
Level 3 with ERK:

    Ron, the reason I'm detailing these issues is that you are a valuable
and highly esteemed source of information for the E36.  When your posts are
unclear on points such as these, it adversely affects the decision-making
ability of the enthusiast and also unneccessarily damages the reputation of
UUC Motorwerks.
