My Evo X Final Edition’s stock brake pads were running low. I recently took my own new brake pads to the dealership for servicing and installing the new pads. The dealership outsourced the 'disk machining' job to some workshop (to my knowledge it’s a business for normal cars but not performance car workshop) because the rotor has to be machined first before installing the new pads. The workshop guys said to the dealership staff that 'the metal part of the rotor is too strong to be machined, we have to slow down' (quoting what the staff told me) to make the process work, but eventually, they failed. The rotor (front one) surface is not flat (described as the wave kind of surface by the dealership staff) after they finished, and it's recommended not to be used. Then, they didn't machine the other front one. The two rear ones were machined. The dealership staff suggests me to get new rotors. The quoted genuine part is $3500 for the two front rotors (I asked that the hats are good - it’s a two piece rotor). However, I suspect that the workshop guys didn't recognise that my rotors were genuine 'performance rotors' which is stronger than the normal vehicle, then they might have miss-operated by applying normal rotor machining process, which damaged my rotor. I don't have a way to prove this at the moment, but after consulting with my car club guys, motorsport people and my mechanics, I believe that I have reasonable doubts that this outsourced workshop should be at fault. This results in that I lost two front rotors that should have more than half of its lifetime and I'm worried about the safety of the rear ones.
I got my car in Feb 2016, only daily driving and hill cruise, but not track days. It’s done 33000 km atm.
What at do you think? Is it the workshop who stuffed my rotor?
The images show the damaged rotor. The ‘cuts’ look rough.

Reason: Be accurate
I would definitely favour filing a lawsuit for this if I were in your shoes, and aiming to settle it by asking the dealership to give me a set of Girodisc rotors. Girodisc rotors are cheaper, lighter, and better. In this way everyone is better off.
WAFJ. The rotor is no harder than any other rotor. They tried to make too deep of a cut with the tool moving too quickly. The place that machined those rotors ****ed up and owes you a set of rotors.
Jesus what a ****ing amateur mistake. Looks like they used a dull tool and ran it way too deep. In my exp resurfacing rotors is not really something that is done anymore. you clean up the rotors and then bed the pads in, or you just replace the rotors with the pads. There is no real reason on a street car that you HAVE to resurface a rotor when replacing pads unless you waited way too long and the rotor surface was damaged.
Someone owes you new rotors, If the OEM ones are $3500 then I would try and get them to pay for some girodisk 2 piece rotors. (although this won't likely happen)
Get in touch with the service manager at the dealership and ask him how he wants to make this right. Let him make the first move, then weigh your options. If he is willing to pay for it all, then no need to get all judge judy on the ****.
We all made it past 2nd grade and should know how to spell.
Voice to text does that to me sometimes, though.
Dealership owes you rotors. I can't believe they are trying to pass the cost on to you.
The bolded word makes it believable...lol. Most dealers will gladly make someone unhappy and likely to never come back over $20. Let alone $3500. Not surprised at all. With enough pushing, he'll likely be able to get this handled though.
The better question is how does a dealership not have a brake lathe in their shop..
