It's the calipers that interfere with the rims, not the disks.

So it all depends on the size of the calipers you are going to use. 300 mm disks are not going to fit within the OEM brake caliper bracket. What calipers are you planning on running?

All parts are OEM. Can i install brake calipers for 300 mm brake disk ? Because i look in some catalogs and the measurement for 278 and 300 mm brake disks are same and i think there is no problem to change to bigger disk, but what about the calipers ?

But here i saw that disk http://www.streetbeatcustoms.com/SP-Performance/Brake-Rotors/Mazda-3-SP-Performance-Cross-Drilled-and-Slotted-Vented-Front-Rotors-_-F26_373/741466/ that is the same measurements like my OEMs..

One question at a time. I have no idea what you are asking now!

I want to know can i take 300 mm disk kit from any other Mazda 3 2.0 liter and install it to my car or can appear a problem like incompatibility?

I'm guessing you have a 2.0i Sedan. In that case, you'd need the 2.3S calipers, caliper brackets, S model pads, and S rotors (300mm). Hope that helps. Or you could just buy the Mazdaspeed3 calipers, brackets, and rotors. The Mazdaspeed3 calipers are the largest.

In the aforementioned six-car comparo, the Mazda 3 s was quickest to 30 mph, to 60 mph, to 100 mph, and through the quarter-mile. In that group, it also racked up the surest skidpad grip, the fastest lane-change speed, and the shortest stopping distance—168 feet from 70 mph, hip-deep in sports-car territory.

See if you can get the 2.3s calipers. The breaking distance is impressive
