    I'm about to do a brake job with Porterfield Pads and my rotors have ridges in them (all 4). (maybe due to racing pads installed by PO, not sure yet, I have a feeling he swapped pads without turning the rotors, pads are still ok)
    My question is how many times can 308 rotors be turned before they are undersized ? (I hate to just swap pads when the rotors are groved.)
    Where is a good place to have them turned? Brakes Plus type of place or NAPA etc?
    (the car has 60k miles, so I assume they've been turned once already)

    The manufacturer usually stamps the minimum thickness allowed into the outer edge (so the shop doing the work doesn't have to try to figure it out and deal with the related "liabilty" issues ;)).

    Nothing special or unusual about a 308 brake rotor so shouldn't be any different cost-wise.

    Read the article on Girodisc website. The way I understood you only have to turn if they are badly badly scored.
