Well the brakes you lose when you use a one-way. I used a one-way in my NTC3. If you have the rest of the car set up then the one-way will give you alot of steering. I was able to come into a corner on the gas more, and still cut the corner close and fast. Try using like quarter throttle through turns, it helped me to get through a little. Once you get used to it, you'll like it alot more.
If you need a setup to start with LMK.
