That's why the stock riders usually use front one-way and center one-way also.
If you ride with stock motor it is reccomended to use one-way because it almost always faster than the diff-diff.
When you use one-way you should watch your driving style, because, there will be no brake with one-way. You will get used to it, don't worry.
You don't need any other parts to use the one-way, just buy the Tamiya's original front one-way set, mount it and go for a ride.
