Start calling local shops, some can. Have you put new pads on and tried bedding them in to see if its just a glazing on the rotor causing your issue?

[crazyasiantl]

i havent tried that yet. should i try that with cheap pads or get something good like ebc or hawk?

also, the front rotors almost look chrome..theyre pretty reflective compared to what ive seen. is that glazing?

sorry..im a brake noob

Get a good pad like the green stuff, they have a good break in coating on them that will help.

I have yet to see a shop that can turn (resurface) slotted rotors. The only thing the shops can do is to grind or deglaze slotted rotors.

My last set of Rotora slotted front were warped, and I had to buy a new set.

This seems to be a popular misconception. I've done plenty of them with the standard old fashioned ammco lathe that a lot of shops use. I've used round bits as well as the traditional triangular ones. I personally think some shops don't want to try them out of fear that they might be hard on the lathe or bits. With an expensive set of roters like dba, I'd call around till you find someone who's comfortable doing them. I'd trust a machine shop that caters to garages more than diy'ers, especially ones that do engine machining as well. You could also try garages that do performance work.

Well, this may be a lost art. With most brake shops nowadays hiring younger lads who have absolutely no idea what an old fashioned ammco lathe even look like, this would be hard to come by.

It also helps if you can give us the names of places that will turn slotted rotors.

I wish I could be specific, but I doubt that any parts chain has a "policy" on turning drilled and/or slotted rotors. You're just as likely to get a skilled old timer who won't even try it , as an eager kid who'll gladly try it and screw it up. Basically anyone who can properly turn an ordinary rotor can do it.
I agree it's a dying art, with the cost of most new rotors being so cheap.
I just think with expensive , good rotors it's worth a few phone calls.

i do it all day at o'reilly including on my own slotted rotors (dba) all it does it skip over the slot. if you can turn a standard rotor, you can turn a slotted rotor. no biggie
