All 4-bolt mounts do the same job really, just some are lighter and more expensive. Standard Echo ones should be fine but if you really want to go fancy get some of the Try-all mounts or the Echo Tr mounts, they take the need of the plastic washers out so you just tighten your bolts and the pads set them selves up square to the rim The echo ones are cheaper then the try-all, so if your thinking about them, get the echo.
