Dimensions of stock front rotors?

Hi all

Can anyone supply all the dimensions for the front brake discs/rotors?

I believe the diameter and thickness is 294x24, but does anyone have the height? Assuming CB is 56.1mm - can anyone confirm?

295x25.5mm if 2009 WRX "beefy" rotor. (http://jamalb.net/pictures/brakespecs/dba_4000_cat.jpg)

294x24mm using the "regular" WRX rotor. (http://jamalb.net/pictures/brakespecs/dba_650_cat.jpg)

Those are aftermarket WRX rotors in stock WRX size. Read the compiled brake info on NASIOC, it's very informative.

That doesn't really answer my question, but do you have a link?

Technically I think this is the size of rotor on the car:



And this is the older WRX rotor:



Pictures are from centric. Not quite as fancy as the DBA drawings.

FWIW, a search of Centric's online parts DB returns 120.47021 on the hitlist as the front rotor for our car (here in the US and the high end overseas models).
