I think you'll find that the DBA648X don't suit a WRX either, for a WRX it would be DBA650X (drilled), and DBA650S (slotted).

The drilled ones are more for show, as they WILL crack around the holes if given a hard time. The slotted ones will stand up to whatever you throw at them.

I have 2 sets of brand new DBA650S available for cheaper than that. PM me for price.
