It does look nice, but at what cost to handling? Then again, I see people buying drop springs that have spring rates that seem odd to me. Or look like they give the car saggy ass.
With sleeve overs, people do exactly what you and I want, equal gap. But I guess that's not good for handling either. So to me, just do whatever works for you. I mean, most m3 owners don't even track it. So if it looks good, rides nice and you're happy, do it!
