they are not floating discs but rigid. Mine went at 6k klm i purchased the EBC floating discs, a bit of a pop at 400 for two on my speedmaster, but they seem to be great discs, very little pressure needed or you will be wrapping your arms around the person in the car ahead of you, you can feel them center up from time to time as well which should help with the warping issue, i learned that many of the front discs on both speedmasters and americas went south very quickly. To soft or something.
PS make sure you replace the pads if you do the discs even if they look like they don't need it.
