Brembo Upgrades for 135i?

Ok, bit of a brake noob, stick with me.

the 135i has Brembo 6 piston calipers up front and 4 piston calipers in back...

rotors are 338x26mm in the front and rear 324x22mm...

Why are there no direct replacement rotors from Brembo available in cross drilled and/or slotted set up? am i missing something?

also, who has done cross drilled and/or slotted rotors and can report as to whether or not they improve/worsen braking performance?
