    Shave rotors or buy new ones?

    What's going on guys. So my early 14' ST needs new pads for sure but, I am not sure if I should shave the stock rotors or just go ahead and get slotted rotors from Stop Tech. Any suggestions on if I should use the stock rotors for another 30-40k miles after they get shaved? Thanks!

    Most of the time you can get new rotors for the same price as getting them turned.

    I would reuse if thickness is good to go or buy new ones. I've never had issues swapping pads on rotors.

    Stoptech rotors (slotted) are fantastic! I'd recommend them.

    Unless you have some uneven surfaces on the rotors (Called runout), you often do not need to do anything, other than a light scuffing with sandpaper, install new pads, and bed them in.

    But moving to new Centric rotors, or even better than OEM is Centric Premium rotors, is so affordable these days...

    I usually can go 2 pad changes before I need to change rotors, assuming street pads.

    Since you have an early 14, have you thought about switching from 12.6" to 13.1" rotors? The caliper brackets and dust shields are about $60 plus the OEM rotors are about $50 each. Stoptech rotors are at least twice that amount, but the cost would be the same whether you went with 12.6 or 13.1. So actually, it would be about $60 extra to get the larger brakes with the better cooled rotor design.

    Add Kevin's rear Frankenbrake upgrade for about $220 and you could have larger slotted Stoptech rotors all the way around. This is what I'm going to do to my early '14 when I need to change pads.

    If your rotors are within spec and aren't warped I'd stick with them or upgrade to a larger size. No need to go to a fancy brand for more $ over blanks at Advance. I use Advance Auto parts rotors on my TT car and when they crack I get them swapped under warranty, and they don't crack any sooner than expensive name brands I have used in the past.

    If you're not doing the brakes yourself, Considering how much money you'd be spending on replacing your rotors, which is about $200 for all 4 corners OEM, you could buy the Focus RS brake kit from Ford Racing and call it a day. It's more expensive, but those should last you YEARS of street use.

    I checked out that RS kit on CJ Pony parts and it's $1440 for the front and $480 for the rear. And the stock wheels won't fit so you'll need spacers or new wheels. The 16" spare on the 13-early 14's might not even fit the rears anymore. So now you'd be looking at $2k plus new wheels if spacers won't work, and a larger spare tire or full size spare. I'm sure they're nice brakes but it would be way cheaper to just replace the rotors and pads, or go the bigger rotor route by changing out the caliper brackets.

    Uh, no. You can get them turned for $10-15 each. You aren't going to get new ones for that, though most rotors can only be turned once. I highly recommend either turning them or replacing them with every pad replacement. All I can say about those of you that say it's OK to sand them lightly is maybe you don't care much about the long-term, or maybe you aren't as particular as I am. I have never paid for a brake job and have done the brakes on all my cars, including several with drum brakes. Additionally, I have had several long term cars, seven, eight, and even two cars eleven years, and one 16 years. My experience says that pads break in better and last longer when you take care with your rotors. Why would you go to the trouble of replacing your pads with Hawks, only to have them have issues after 10k miles because of uneven rotor wear?
    Do the right thing; turn or replace your rotors when you replace your pads.
