After STFA have a question on brake replacement
 

pretty sure my rear brakes are in need of replacement so, I'm taking this opportunity to:

Replacing OEM fronts with DBA 4000k rotors and Hawk HPS pads.

Then considering upgrading OEM rears to S8 rears and Hawk HPS pads. My question is are the S8 rears a waste with the HP2 fronts? Would replacing the rear rotors with the OEM sized AWE slotted be a better option.

No plans to run a BBK in the front anytime soon, but there is always that chance of an upgrade though (come across a great deal or something). The car is never tracked and probably never will be.

S8 could be OK depending on pads but probably not nessasary esp if you're not planning on BBK fronts
