I am not using the black reinforced gears in my m03, but I think my gearbox problems are due to the fact that I was running it with a 7t brushed motor for a while , bashing around before I switched to silvercans... The new bearings I put in there did not fit smoothly, but I did not want spend too much on the car, so I used the 1mm washer to space things out a little inside the box... It got smoother as I kept running it, but I am sure there is still some friction in there......

If the stock gears are used, it is impossible to build a rough gear box in a M03. Yes, the parts need to be in good shape, but that's a given.
