Short Shift: Z3 or Motornix

[BMW BMXer]

Ok for the z3 I got this parts list:
1 25-11-1-220-379 Spec. circlip (infamous bitch clip)
2 25-11-1-220-439 Spec. shim
1 25-11-1-220-832 6-Bush Bearing
1 25-11-1-469-397 Trans. Shifter bushing
1 25-11-1-434-148 Shift lever (Z3 1.9)
1 25-11-2-225-369 7-M3 bar (bow)

Now I called the dealer and they tried to sell me a bunch of other crap with it.

I want to get ride of some of my side to side play and shorten the throw a bit. The side to side play in my lever is pretty bad the dealer said I might need a selector rod and all this other stuff and the price kept goin up

The shop I am going to has the original lever and bushings, and I assume the rest of the hardware for my eta.

Should I just pick up the z3 lever ($94 cdn) or do I have to get the parts listed above? I am trying not to get raped here.

OR
should I just get this shift kit http://www.motronixmotorsports.com/p...er&cartype=BMW and save myself the hassle of tracking down parts...



ANY HELP would be good
thanks
