the quad brake conversion comes with normal disc`s,the 7075 cnc disc`s as far as I Know are 4 disc`s 8 pads, code no H87345. There is also a plate that fits under the disc`s that is differant between two and four plate brake`s, which you should get with the conversion.
I`m runing quad brake`s with cnc disc`s and abs once setup there`s no fade and they stop my hyper on the dot!
