Re: 89 m3 shifting

Sure -- I've done this...  

...on a Fiat Uno Fire 1000 (Fire meant that it was completely built by
machine without human intervention -- so I was told -- until final
inspection.  I think the tolerances were a little loose :=)) when I was in
Italy.  Just needed a little more effort :=)....

Since its your car, and you have a working clutch, why not use it?  "Real"
race cars whose drivers shift without clutching get rebuilt after every
race -- do you wanna do that?

If you do, it will work at just about any RPM on your or any other car --
you just have to know what revs the engine will be running when in the
next gear and engage at that point (after either letting the engine slow
to that RPM or after having blipped the throttle accordingly).  This is
basically the same routine you should follow when rev-matching and
double-declutching anyways, except that you';ll be skipping the clutch
part.  Again, do you really want to risk damaging your tranny so taht you
can boast too?

Anyways, you'll need to either figure-out what revs go with what MPH in
each gear (using your final drive ratio, tranny gear ratios, wheel+tire
radius, 2*pi, etc.), or just drive alot and take alot of notes in your
head regarding what speeds equal what RPMS in what gear.

Good luck.
