    you need to measure the thickness of the rotors and find the machine to specification to determine if they can be safely cut. if they are within specification then it is perfectly safe.

    +1 measure the rotors....you should be able to machine the rotors if they are thicker than like 22.5....22 is the min. after cutting...you can usually get about 2 cuts out of a set of rotors.....if your planning on doing the rear you should have at least like 9...8.5 is the min. after cutting......however if the rotors are to thin....you can go aftermarket for the rotors but when it comes to pads stick to OEM or a decent aftermarket brand such as Hawk or something....personally i would not buy NAPA or autozone pads...we get cars all the time with brake squeal and such due to aftermarket brake pads ( if you really take the time to compare the OEM pad to like a NAPA pad the dimensions are completely off..i even know some people that have had to grind down the tabs on the end of NAPA pads to get them to fit properly)

    yea nothing is more aggravating than cut-to-fit brake pads.

    The only bad thing about turning rotors is that they will warp quicker than new ones, meaning you'll be back replacing them sooner. IF you have the money get brembo blanks or OEM rotors and slap on a good set of pads for a DD.

    If the rotors are the originals, then I'd bet good money they need to be replaced. The only way to tell what to do is to measure the thickness though. There's really no need to grind them down unless they have big grooves or other inconsistencies. Just replace the pads and within a few hundred miles the pads will conform to the shape of the rotor. I never bother having my rotors machined. I just replace them every second set of pads. Well, normally I would, but on my STi I got 55k miles out of my first set of brake pads and I don't know if my rotors will be able to make 110k miles when I expect these pads to wear out!

    I took the rotors to pep- boys, they said that they were thick enough to have them shave so I did that for $12 it'll be good for now but next time i know i have to buy new ones. The only thing that I really screw up is that one of the bolts that holds the caliper was so rusted that the head broke off, but i was able to take care of it

    thanks for all of your help guys.
