The main reason is unsprung weight. Those 4 / 6 / 8 pot calipers come at a hefty weight penalty. Unsprung weight is the mortal enemy of handling.

This is a sore spot for me too. As a roadcar, floating calipers are fine but as a trackie, you really need at least 4 pot calipers or bigger for a car that is 3600+ pounds.

I remember once, I was following a Z28 SS (floating calipers like BMW) down a straightaway, I saw the brake lights but he ran right off the end of the track. We looked at his brakes and they taco'ed. The brake caliper instead of being a uniform "U" was a wide open "V". At full extension, the pads didn't even touch the rotors.....

So if you track your Bimmer, get some aftermarket brakes. For a road car, they are fine.
