Installing MazdaTrix Short Shifter - Use included bushings or new Mazda bushings?
 

I bought a new MazdaTrix S5 short shifter with supplied bushings to put in my 88TII (S4) and then bought 2 official 8AF1-17-481 Mazda bushing sets as well. I wasnt sure, so I bought an extra set because I heard that a bad set of bushings can mean all the world of difference between a good feeling and a bad feeling when driving.

In looking at the two, the lower Mazda bushing is quite a bit softer than the lower MazdaTrix one and there seems to be barely half a 1/16th of an inch difference in height between the two (The MazdaTrix being the taller). The MazdaTrix upper bushing looks exactly like the official Mazda bushing (same color), only it too is just barely taller and is a tad softer.

Is any one better than the other performance wise? Life span wise? Fitting/Installation wise?

Thanks

first use what came with kit from Mazdatrix (its meant to work together) and if that does not work right, try other set :D
