Example: let's say you are making a hard right turn... The outer wheel will naturally want to rotate more since it has more ground to cover than your inside wheel.. The more time your wheels stay planted to the track, the better traction you have..
A standard 4WD diff tries to rotate both front wheels at the same constant speed causing the outer wheel to slip a little every time you make a turn. Some traction is always lost when this happens.
A one way can 'free wheel' your front wheels allowing the outer wheel to rotate at a different speed than your inside wheel when you make a turn (same as a 2WD car). This means more traction every time you make a turn and a little better chance to make faster turns that the other racers.

It's nice to have once you get used to using one. The Front One-Way is specifically for indoor higher traction surfaces where your wheels will stay in contact with the track most of the time.
The Center One-Way is specifically for off-road tracks where the front differential action is still required to maintain grip over bumpy and loose surfaces.
Hope this helps.

That is just wrong. You have it completely the wrong way round. The whole point of a diff is that it is there to allow the wheels to rotate at different speeds (hence the name differential) so that there is no slip between inner and outer wheels. This is one of the disadvantages of front oneways replacing diffs (centre one ways allow you to keep the diff operation at the front).
What a one way gives you is more turn in by removing the breaking on the front wheels. The wheels can only provide so much traction or grip. In
permanent 4WD the front wheels have to brake and turn. With a one way all that grip can be used for more turn. However your breaking is much reduced.
