Standard shocks question please

[Paul02]

Hello again , did quick search but couldn't get answer . Looking for standard type rear shocks not Billies or anything as stiff .

Is there anything else avaliable off the shelf other than Bmw part no. 33521113758 , and I don't even know what they are .

Many thanks
Paul UK

Have you tried Jaymic, they once had some? Fay is also very helpful.
