Re: AMD
I never binned them I sold them actually to another forum member (for buttons and was aware of the issues) who tried them and he then got rid also! I then stuck some ceramics on. twos up to you saki, I'm sure you know what that means

Re: AMD
This is on the net too...
First we need to look briefly how discs work. Through friction, we convert forward motion into heat. The heat transfers mainly into the brake discs and pads and they are effectively ‘air cooled’ by the speed. As the disc starts to get hotter it expands. Then as it cools it shrinks back to exactly the same size and shape it was before the process started. The trouble is it can only do this within certain parameters and if the disc gets hotter than its maximum temperature then it will no longer return to the same size and shape that it started. It will cool as a totally different shape. In other words it is warped.

Re: AMD
Source?
My information was from Stop Tech, one of the largest brake companies in the world, and was written by a race engineer.
Your information was from a blog, and was not signed or attributed to anyone. The site was selling brake discs...for motorcycles. In other words, 5mm thick, weighing a pound. Further, it was for race applications. He was referring to using far too thin discs for inappropriate applications. Further still, you failed to quote the part where he described super cheap, thin motorcycle discs as being potentially warped (still with no backup or data to support the claim, just hyperbole), pushing visitors to the site to buy higher end (higher margin) items.
We on the other hand were talking about 20lb rotors for street cars.

Sorry for helping.
Re: AMD
Oh, so that makes the information wrong then, so metals don't expand and contract with heat, build up on discs does happen, agree, high spots on the discs causes hot spots and uneven temps, a disc cooling unevenly will warp, twist, buckle or whatever you want to call it... Source, 5 years motor racing, bucket loads of discs, lathe and dial gauge, an apprenticeship studying casting and metalurgy, could be wrong though

Re: AMD
What's my comment got to do with what you've mentioned?? Just saying JHM for the winOh, so that makes the information wrong then, so metals don't expand and contract with heat, build up on discs does happen, agree, high spots on the discs causes hot spots and uneven temps, a disc cooling unevenly will warp, twist, buckle or whatever you want to call it...
