Lowering of an ABC suspension

Hello everyone. I have a question, of which I think there are certainly different people here in the forum who can answer it. How can you lower an ABC chassis without necessarily buying an additional control module for a lot of money? I thought so in real sensors or poles or so (to modify this). Workshop with a lot of skill and understanding I have at hand – just wanted to ask here before to not unnecessarily drag the whole (the work) into the length and we may not answer the wrong part first and try. Thanks already in advance. Oh and still what – who can not post anything on my question, it should let – so no answers like – why do you want to lower is shit etc. Please only posts, who can answer my question. Thank you!!! I believe that you have to write this right here otherwise trash me here with your advices etc. only too! P.S. Who does not want to post it – then gladly by PN
