Redun and I both have them fitted buddy As per your rear ARB thread
They should be for E46M3
They should be purple blue in colour and bigger not by much but trust me once on car they sure feel better
They should nicely fit rears the same and come with D rubbers
I believe they do a set of H&R for normal Zs
But they DO NOT fit rear as diff in way
As dub says buddy
I'd politely say funk this I'm taking my car elsewhere to them buddy
Just checked your link from.dc guys I get my stuff from them
But sadly buddy for sure that's a standard z4 set up you've bought and your M ones are already larger and stronger than that
