That's totally wrong.
With 12 screws you can have COMPLETE access to the WHOLE drive train, including the front and rear gearboxes, spur gear etc...
13 screws if you use the central stiffener.
It's still more than on the SD or Evo 3, but I find it very nice to be able to do that, you have a clear view of the drive train.
Back to the subject, both are very fast, and both hard to maintain. Yet I found a belt driven car should be easier to drive than a shaft driven car, because the drive train feels smoother on power.
