To be quite honest, I do not think it is such a good idea. I read the other threads about all the mathematics and science behind the springs (not too difficult)... but to make it easier:

Springs are expensive, especially OEMs. Not sure the price, but if my old car's springs were expensive, I should think a car which is basically a Mercedes would have expensive springs too.

You cut those, and you'd better like the results. Otherwise you damaged perfectly fine parts on your car... and now have to go buy new ones.

And as ppro said, there are lowering springs. It would be easy to just try those or ask around about what you are looking for looks wise and performance wise, rather than cutting up your car's parts!

It is just a fact of more things can go wrong than right in this case. But people have done it on here to their Crossfires and they seem to like it. You could buy lowering springs, try them on... if you like them good. Then you can sell the OEM springs and probably break even on all your expenses.
