so i think i need new rotors because i have steering wheel shimmy while breaking at high speeds. do i need to replace all four rotors? i have an 08 v6

I had your same problem, my front rotors warped causing a braking shimmy as well. Replaced my front rotors and pads and the problem was solved.

You will be ok with just the fronts. Only change the back ones when needed. I had the same problem. Thought about getting the rotors machined, but it was just simpler to swap them out.

You can just have them turned. My local alignment shop charged $70 to remove, machine and replace the fronts on my wifes car. Didn't even need new pads. New rotors were twice that price.

Orielly's can turn them for you. Dont know what they charge though.

If you're going to have them turned, it's best to have them turned ON the car as opposed to removing, turning and reinstalling the rotors.

When you have them turned on the car it also takes in to account any lateral runout you have on your spindle/hub from surfaces that don't mate prefectly between the spindle/hub and rotor. In other words you get a more true turn.

Any shop these days that has decent brake service capabilities should have the equipment to do an on-car turn. If they don't, look elsewhere.

For reference, one brand of an on-car lathe is called Pro-cut.

Front rotors, steering shimmy, rear rotors, brake paddle pulsates. I would never turn the rotors to cure the problem. Always replace the rotors. The reason for the problem is due to the thinning of the rotors. When you turn the rotors, you put a band aid on it, and the problem will come right back and worse. Always replace the rotors!

Nothing wrong with machining rotors. When they get thin, close to the spec, yes they will warp easier. But have you seen the thickness of the rotors on these cars. It takes a lot of heat to warp them. If you are constantly doing it you are either riding the brakes or needing to invest into some better race style brakes.
