I am not sure about the actual measurement but I knew that the brakes we have comes from E3. I think you'll need to open up and measure. Sorry can't help much.
I read from a few forums that some claimed Airtrek Turbo is actually manufactured from 'remaining unused Evo parts'. hahaha.. not sure if it's true. I knew that brake from E3 and engine internals and blocks from E4/5. So just to clear the store, they made Airtreks. haha...

Honestly, the brakes are actually fine for stock. BUt if you increase the power even slightly, it will not be able to handle the car. This is because it's over 150kgs heavier than Evos. So the extra weight is killing the 2 pots calipers.

They ran out of Remaining Parts, so that was the end of Air Treks......![]()
