you can get vented disks. I used a brembo vented/mintex pad combo and they were very good. However, the problem comes with the calipers. you need calipers that specifically go with the vented set up, which are only found on early K11 march imports. Some people say you can grind a bit off the claw of the caliper, but i dont really see that as being safe.

Well the calipers are newer than K10 ones so yeah they've got to help, definitly cant be any worse. The disks & pads obviously assist in making a huge difference too.
Brakeparts (i think) sell vented disks and calipers for the K10. Trouble is finding them in stock!
if i were you'd i'd just get a new pair of standard disks, mintex pads, free the caliper sliders off, change the back cylinder, adjust the shoes and change the fluid, and you should have superb brakes.
