Lastly you can over tighten the plastic ones and crush them against the outer bearings. I have done that on my original R40.
Yeah X 4 and its directly connected to the wheels. Its well worth doing this if your looking for performance. I can talk about unsprung weight of the wheels all day. This is essentially like getting lightweight wheels for a real car.
The unsprung weight of the wheel has a lot to do with how fast a car can accelerate. If you like lightweight shafts and 2speeds. This is almost the same effect but great in a sense. It should also increase handling efficiency.
I have lightweight rims for my real car. Its like night and day. Car becomes more responsive , doesnt get bothered by bumps as much , acceleration and braking is improved.
Ill just replace them if needed. I never had to with my racer2. But well see.
