DBA Rotors for Big Brake Upgrade?

[Staaahp]

Hey guys,

Gathering parts to do the big brake upgrade next weekend.

Got NB8A calipers to put on with some HEL brake lines and bendix ultimates.

Had my heart set on DBA 4000 T3 slotted rotors, but i'm actually not too sure which model to get. Does anyone have the product code for the Rear/Front model to suit NA8/NB8A?

Also does anyone know where to source them cheaply?

Thanks all!

255mm - DBA 4538S - Front

250mm - DBA 4534S - Rear

Bump, some searches later would indicate the above ^

Anyone know some good sellers re brakes?
