The only problem with the chinese rotors is that they are not floaters, at all.  The buttons are as solid as you can get them, so any wobble is translated as a surge in the brake line and you feel it.

I have had mine on my bike for a couple of years now and, having ridden plenty of ye olde Ducatis with fixed rotors, I was used to it.

The carriers and the surfaces are very good. Mine look great too, after 2 years.  The only pregnant dog I had is the buttons and that's possible fixed by fiddling with them.

I did have several conversations with the makers of the ones I got and I believe they are now shipping them with buttons that have about 1mm of play, making them semi-floaters, like the standard Brembo disks.

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

that sounds like the ones S3 sell out here.  the local disc grinder used to do them new for them as an additional cost option and also redo a few due to warranty issues, but said he hasn't done any for a while.  so maybe that's all it took.

the floating thing is funny.  anyone who worked at a bmw dealership during the r1200gs days know how many variations of disc mounting they went through to try to stop them warping.  it was quite amazing the stuff they did, none of which really seemed to solve the problem bikes.

were those bmws stainless or iron?

i never had any warping on the old fixed cast iron type on my pantahs.  they were >6mm thick though, pretty hard to warp
