To be clear, in street touring both adjustable and non-adjustable camber plates such as Dinan are considered upper camber adjustment. If you use them, it is not legal to use the M lower control arms.
However, as silly as it is, you can take the stock arm and add an offset bushing which results in the arm being the same length as the M arm, and use that in conjunction with the camber plates.
This is my post describing doing exactly this for STX competition:
