Brake Rotors Don't Warp
#33
I think he means (like a lot of track people) that he pefers slotted/drilled but for intense track use since blanks and drilled/slotted crack anyway he perfers to go for the less expensive blanks. He doesn't question the funtionality but the amount of rotors he needs to go through regardless if they are drilled or blanks.
in any case both of you guys seem to take this whole thing to an entirely different level. when it really comes down to it, a good driver and a good set of tires is all you really need.

Then he goes on to say that he doesn't use drilled/slotted rotors....but rather uses blank rotors that he cracks every 3 days and has to replace.
Sorry, but his posts make no sense. He's a cheerleader for drilled/slotted rotors, yet he doesn't use them himself, instead choosing to crack and replace his blank rotors every 3 days. That's the very definition of hypocritcal.

The additional functionality of drilled and/or slotted rotors serve me, in my particular car, in my particular situation, no purpose on track. The rotors will crack regardless.
Again, reading comprehension failure on your part. I clearly stated that aftermarket slotted and/or drilled rotors are cheaper than OEM blanks. True. I also stated that my blanks are cheaper than drilled and slotted rotors. Also true. The blanks I use are not OEM. True yet again. As stated before, there is no advantage in me running drilled/slotted rotors, when they cost more, and offer me, in my situation, zero benefit.
I sincerely doubt there are more than a handful of posters here who regularly heat their brakes enough to make them glow like I do. I fully acknowledge the potential benefit of drilled/slotted rotors. Unfortunately, in my case, reaching equilibrium temperature 100 degrees lower doesn't do much, when your rotor temps are nearly 4 digits.

As I've stated before, if you track your car with any degree of proficiency, you would have run into brake issues at some point, and experienced these issues firsthand.

Proper research involves reading and understanding the entire subject
Has anyone ever seen a warped rotor? If so, I'd love to see a picture of it. Maybe even a video of the rotor on a lathe with a dial indicator attached to it.
Why is it that doesn't exist? Think about it? LOL
"In fact every case of "warped brake disc" that I have investigated, whether on a racing car or a street car, has turned out to be friction pad material transferred unevenly to the surface of the disc. This uneven deposition results in thickness variation (TV) or run-out due to hot spotting that occurred at elevated temperatures." - Carroll Smith, StopTech
'nuff said.

Key words: worse, spiral (warp, loophole),drat!, cementite = atom of carbon.
Cementite (warp, spiral) exists in molecular level. Very hard to take pictures of them with conventional camera. I believe in Caroll Smith from StopTech.

A 1999 Grand vitara I serviced had a completely inoperable front left wheel. upon further inspection we found that the disc rotor was so deformed that it was jammed up against the caliper bracket. With the rotor removed and placed on a flat surface, it was clear to the naked eye that the surface was severely distorted.
The car was driven by a young graduate student who did complain of various braking issues but was too busy to bring the car in.
resurfacing the rotor resolved the issues.
----------------
in the country I worked in, new rotors were prohibitively expensive and were not replaced until they were potato chips

As usual, you simply choose to ignore all counterpoints and presented evidence. Please, stop spreading misinformation. Are you a mechanic by profession? By personal interest? Hobby?
Let me guess. You think wings are for track use only because they don't make any downforce at street speeds, right?

Good. And here's a quote of his:
"In fact every case of "warped brake disc" that I have investigated, whether on a racing car or a street car, has turned out to be friction pad material transferred unevenly to the surface of the disc."
Glad to see you believe in him.
