My front rotors are warped from the track using Carbotech XP8 pads. I need a rotor that can hold up to heat better than stock.

From my research, it seems like the Racing Brake 1 piece slotted for $126 may be the best. They use an alloyed, gray iron and heat treated (not sure what our stock rotors use). Plus the slotting may help a bit.

I'd like to go with their 2 piece rotors for even better heat dissapation and lighter weight, but they $305 per rotor. This rotor uses a Racing Formula alloyed gray iron and heat treated.

If the 1 piece will hold up, then that would be fine with me. But if they end up failing, then of course the 2 piece rotors would have been the better choice.

It's $360 more for the 2 piece rotors...but I'd rather not spend the extra if it's overkill.

Any opinions with those who have had similar experiences or direct and accurate knowledge please respond. Thanks in advance.

^ Those are race pads, you should not use them on the street. It'll kill wear out your rotor as well as your pads. I swap out those and bobcats for the streets on the same rotor, no problems. As long as you buy from a good company it'll all be the same I use StopTech slotted rotors, they are good.

I have the 2 pc rotors and they wear like iron (duh)

They have been through about 8 sets of pads and the wear is still in spec

Can't compare to the 1 pc though as I never went there :)

I bought a spare set of rotor rings for the front and they are still in the box........great economy :) but I never expected the first set to last as long as they have

I use the XP8s for the track (road course, not autox) so they are good there. I agree I need to start swapping out for the bobcats.

I checked Stoptechs site and they don't currently offer rotors for our cars...maybe I missed it.

From RacingBrake website:

NOTICE
(TRACK RACING ONLY)

RB two-piece rotors are made from specially formulated alloys and high carbon cast ion and are proven in the race tracks that they are highly resistant to wear, warping or thermal cracking under extreme heat cycles than OE or others.

Since our disc material is different from OE or other rotor manufacturers, the same racing pads you used to know or install (typically Carbotech or Ferrado) and work well on these rotors may not function satisfactorily on our rotors. One of the most common issues is the pad deposit which is a substance emitted from the pad under high heat and transferred to the rotor surface that can cause vibration, pedal pulsation and hot spots on rotors surface resulting in thermal cracks or pre-mature brake failure.

It?s your own protection and responsibility to ensure that you use the true racing pads that used by professional racers like Hawk, Mintex, Raybestos (Porterfield), Cobalt or Pagid that can really take the heat without pad deposit concern. Nothing comes without a cost, professional racing pads prices are usually 20-30 percent more than Carbotech or Ferrado which are more popular to weekend racers.

Also, your rotors are probably, simply, "warped" (quotes used on purpse) with uneven pad deposit. You can try to clean the rotors and rebed the brakes, or have them turned (though turning cuts rotor thickness, so be sure they're still well within spec. after being turned) to clean the rotor surface of uneven compound deposit.

Oh and I think that carbotech might have deals where you can get black rotors for 25$ each or something when you buy pads.

i have run the carbotech xp 8 for nearly 3 yrs now and i have never had any rotor warpage. ??? I do run high speed tracks, r compund tires and i do run oem front rotors (they are pretty good). look to see if something else is causing this prob because i dont think it is the pads and the oem rotors are even used by race teams.

^ If you swap out between race pads and street pads, the rotor will get glazed and messed up.

not if you clean your rotors before putting the other pads on--thats what i have been doing for 3 yrs now--seriously

Yup. Also, staying within the same family of compound material also helps.

hands down; Centric, at $60 each you can afford to have multiple sets and change them with the pads

I thought it was uneven pad deposit too. But then I took them to get turned and the tool was fine on half the rotor and didn't touch the other half...definitely warped to my surprise.

Next time, I am buying Centric rotors for ~$65 front and ~$55 rear ea. I don't see any need to get slotted rotors. It's either that or a two-piece dBa if I wanted go all out.
