You would have to file a mm off the bottom of the old suspension mount. I just tried putting the older taller one piece mount on the front and it does give you a little extra toe out. But, it looks like if you filed a mm off the bottom to reduce the height the belt would rub on the underside of the mount. The picture supplied looks like there is a 1mm spacer under the mount? I am running the new solid SD-300FR with 1mm spacers and it was designed to clear the belt on the BD. This came out with the new SD-300RF for the rear of the car. The old style are not being produced anymore, this is a part that is being changed with no new part number.
