Hi, I run slotted & green pads on all corners. They are brilliant, I do a fair bit of towing, without trailer brakes, & I have always been happy with the slotted discs. I travel between Melbourne & Gympie at highway speeds towing about 900kilos of trailer and the slotted really can handle the extra load. They are far better than stock. Just around town they are a little overkill, unless you give the brakes a real workout on a regular basis.
