2007 g6 needs brakes and rotor replacement
I bought a 2007 g6 last july. Within less than 5k miles my rotors were warped and were changed before the car was sold to me. I went to napa and they told me they had two different sizes... I went with the 11.7 size rotors and put them on my car and started to hear scratching so I went back to napa and got the 10" size.. 9k miles later they warped.. so now, I'm puzzled... Can anyone tell me
A). Which size rotor is correct?
B). Which slotted and drilled rotors do I go with? (Because most likely I will end up buying those)
