Ok... well I am on a big money crunch now so I need to go with the cheapest sadly... so if I order these two from autohausaz.com:

MDB1369 Mintex
Brake Pad Set; Rear; OE Supplier Compound
1 set per car
$32.75
_____________________________________
34211158936 Balo
Brake Disc/Brake Rotor; Rear Left/Right; Solid 280x10mm
2 per car.
$38.95
(x2 right? so total $80?)

Grand total: $110 [for pads and rotors]

and bring to my mechanic, he should be all set to replace the rears correct?

Thanks guys!
