Did you try what RANS suggests for the RadLoc seat clamp? Piece of innertube around the plastic piece on the bottom. They also sell a little retention device that mounts on the rail just behind the clamp.
The plastic retainer for the idler can be replaced by any number of pieces, such as a pen tube, or odd bits from the hardware store. RANS sells replacements.
Was something rubbing against the back of the seat mesh? Or, on the front?
Does your rack work for you at that angle?
They have since changed the design of the sprint braces. (I have an '08)
