Well, H&R doesn't make "springs engineered to work on a specific model" for this car. They only make the sports "specifically engineered for" the 328xi.
If the standard is just to look cool, only an idiot would make such a terrible performance based decision. Your car will ride like crap, and you'll ruin the struts with both options. Might as well save some money on your ricer, if that's really all you want to achieve anyways.
Personally, if you're looking to upgrade your suspension on a BMW, I'd want to do work worthy of a BMW and accomplish more than just a tucked/slammed look at the expense of the driving experience.
