This is how my discs are mounted... Wonder why they are all fitted on wrong side?????
They are mounted backwards they need to be flipped sides. Just went out to my car to confirm and double check.

Air goes into the center (backside) and thrown outward around the circumference via centripetal force (or is it centrifugal?)...a mini air pump.

The discs are backwards...likely typical street driving is no impact.

Hmm...the slots on my slotted Brembos face the wrong way. My friend and I were discussing this a few years back. I think the internal directional vanes between the discs go the opposite way though.

Brembo BBK rotors are different from our stocks the slots on those go the same direction as the OP's car, opposite from our stock rotors. OP's rotors are indeed the wrong direction just needs to flip sides that's all.

Our breaks are a Volute (pump), I'm sure there is another name for the air guys, but that's what us fluid guys call it!

Pumps from center and increases the volume and velocity at the tip speed of the outer circumference. Classic pump design and highly efficient. It is very easy to reverse for those that don't understand the dynamics. Many want the tips to scoop the air, but this is not efficient as the veins get smaller. This increases energy needed i.e. increased pressure and reduced velocity. This will cause increased heat and a less efficient pump.

Cheers
