you have to run the disc just below the width of the cut out on the calliper body do you not, making sure that your pads are clear with the pistons fully retracted?

Problem I can see here is the low ofset, and the TCA limiting how far the bell can move the disc back, and the wheel limiting how far you can move the bracket out. And are not most if not all decent callipers like brembo and AP's all radially mounted anyway?
