The big problem with M3 control arms is that they put the top of the wheel in, reducing room in the wheel well.
You can get adjustable camber plates for stock springs - this is probably your best bet. There's a hack where you can also flip your Dinam camber plates and install the adjustable camber plates to them.
You can see an example here:

I had to order longer bolts for the Dinam camber plate, but it worked well. Could get over -4 up front with these.
