anyone running dual master cylinders/No ABS

[Ikrana]

Hi everyone.

due to regulations i need to upgrade my master cylinder on my car.
now running 328x28 4 pot front and 295x25 2pot + 1 spot caliper rear.

I wonder if anyone have any experiance running a mr-s without ABS? and how the car feels and handle?
or if anyone fitted dual master cylinders. or did anyone maybe just change to a diffrent bore cylinder that fits bolt on and in that way keep the ABS?

any input would be great.

thanks
Robert.
