24" on a stiff bmw, you better pray to never hit any pothole bigger than a nickel. Then add on the cost of all the stressed suspension components, like ball joints and such, and you will be one broke mofo. You think 24" will be pimp. I'm curious how you will find replacing $500 control arms, and doing an alignment every 3 months. Or how you will achieve the "correct", and clearly out of spec alignment that will prevent your rubber band tires from being eaten like crazy. Or how much do you think you will enjoy replacing 24" tires. I understand you can buy cheap shit, but that is what you will get, cheap shit.
