What Does W Or W/o Flange On Mounting Hat Mean?

[CitizenPete]

I have RX300 AWD 1999 and I want to purchase rotors here: http://catalog.autohausaz.com/autohausaz/d...rt=Brake%20Disc

What the heck does this mean?

"Must know which type, WITH or WITHOUT "flange" on the mounting hat. 43512-33100 is Type A- WITHOUT flange 43512-48011 is Type B- WITH flange. For models with production year from 1/1998 to 1/2003."

Do I need the flange or not???

thanks for any help with this.

I am not sure what they are referring to but at least they do give you factory part numbers in the red text. 43512-48011 (with flange) is the only front rotor I know of for the RX. Go to irontoad.com to see the part #'s. You may even want to buy them there.
