The one step further crazy idea is if the F85 front calipers would fit! 6 pot instead of 4 which would be amazing.
Since the front rotors are the same size on the E70 M and F85, one would assume the caliper would fit the rotor the same, but question would be if it fits the knuckle on the hub.
E70 M
Front rotors: 395 x 36
Front Calipers: 34117847241/2 (4 piston)
Rear rotors: 385 x 24
Rear Calipers: (matches F85) single piston
F85 M
Front rotors: 395 x 36
Front Calipers: 34117852967/8 (6 piston)
Rear rotors: 385 x 24
Rear Calipers: (matches F70 M) single piston
