If you learn to use the one-way properly you will be able to run fast and smooth without using brakes. A one-way is basically a solid axle that gives semi-diff action in corners when you release the throttle. So, you go into the corner fast and hard (the front of the car will push slightly) then you simply release the throttle and the diff action will take effect and the car will cut into the apex without braking. As soon as the car cuts towards the apex learn to get back on the power as soon as possible to get the car back in the locked front axle position to get the most benefits down the next straight.
