Well to be clear in the case of one rotor there was a radial crack from the outer edge to the hat, then a 360 degree circular crack around the hat. On the other there was a radial crack from the outer edge through the hat to the centerbore. I don' t want anyone to think I was left with two rotor halves. Though one rotor was it two pieces, it did not fall apart completely until the wheel and caliper were removed.
Yes, I'm lucky, maybe I should buy a lottery ticket--or maybe I just used up all my luck?

To add to Kurt's comment. I was indeed puzzled when I was replied by one of their reps that for track use, I should use a two=piece rotor, and that their one-piece rotors were not intended for track duty. My reply was quite polite, explaining that thousands of e30 owners track and even race on tiny 260mmx 21mm rotors with aboslutely noadverse effect, at least not to the magnitude that interests us: we are atlaking about a crack that splits the whole rotor in two, and a hat that separated from the friction surface.
I guess that my explanation was clear enough, which resulted in RB agreeing to replace the rotors and have their tech department inspect the two "defective" rotors.
When the Street kit was offered, I had the choice between several rotor manufacturers: ATE, Balo, Brembo, and then somebody noticed that neat RB disc with the venting located like on a BMW: inward. and it was a pricey option which doubled the price of rotors. Rotors looked good and it was my pick... So from now on, I will keep on offering it, but for street duty only. Trackers may elect to choose the usual high quality, yet cheaper, Brembo, Balo, Zimmerman, ATE.Leave a comment:

Well, In an effort to be fair, we should let RacingBrake investigate the cause of my rotor failure.
I will say this though. Many of us have been spoiled by high quality OEM German parts. I know that I have run severely heat checked rotors for many track days without ever having a failure. With rotors like Brembo and Balo, I could continue to run them until they were at minimum thickness. It should be common sense that you should check your rotors after or before every session to make sure that any heat checking has not worked itself to the outer edge of the rotor. Nevertheless when you are used to high quality rotors that last a certain amount of time (10 track days, 15 track days, etc.) its easy to get lazy.
My rotors failed after 4 track days (actually only 3 days worth of sessions). I did check my rotors before the session in which they failed. There was a lot of heat checking, but I did not see any heat checking that had migrated to the edges of the rotor. That said, its was more of a cursory glance than a thorough inspection. When the rotors failed they exhibited a vibration which was felt through the pedal and I left the track immediately (thankfully via the pit entrance and not via the wall or tire barrier ;) )
I would not expect RB to warranty anything that was used on track. But like Lee, I was a bit surprised when they said that their Corrado rotor was not designed for track use. The company name is RacingBrake after all. I was also highly disappointed with the short service life coupled with the way in which the rotors came apart. After some prodding RB has agreed to examine the rotors and get back to us. I think we should leave it there until they have had a chance to inspect them.
However, I would encourage and Street Kit users who are using the RB Corrado rotor on track to be very careful. You should probably not wait for the heat checking to migrate to the edges before replacing them.

Anyone w/ experience with "Brake Performance"
Seeking for people who have had rotors from this company.
And with especially their Corrado rotors. In all honesty, Kurt and myself are experiencing some serious disapointment with RacingBrake's service and products. Therefore I am seeking for an alternate supplier of Corrado discs.
I will be upfront with you guys, I am extremely disapointed when a company rep tells me that RacingBrake's rotors shouldn't be used on a track. I will disclose more, later, but just to reassure you, there's no problem at all if you use the Street kit on the street. If the kit is used for track purpose, it seems that RacingBrake will not honore any warranty, which is pretty disapointing when you have "Racing" in your company name. More later.
Kurt, if you want to add details, it's up to you.
