does this explain why when i drove my 440i with passive Msport and an M4C back to back on track, i wasn't impressed by the M4C at all?

Not quite. I'm not sure what about the M4 ZCP you weren't impressed about, haha.

So, if you were going to improve the stock suspension on a F31 (B46), street use only, don’t want to lower it much, but remove some of the float and roll, what’s the best option? I’ve read all the posts but I don’t see any consensus.
