My stock rotors "warped" years ago. This is no surprise, road brakes just don't seem to be able to keep up with the conditions here (my 350Z is the worst culprit, disks and pads have been changed, the brakes still belch smoke and judder like mad after half an hour of hard use).
Anyway, since the stockers had warped I ordered some Galfer wave rotors. When they turned up I was pleased - look great, way lighter.
In the meantime the stock rotors UN-warped. I go along with the theory that disks don't warp, they just get uneven deposits of pad material, and if you are using abrasive pads eventually they clean themselves up (until next time). So it was years before I fitted the Galfers (house moves and other chaos).
When I fitted the Galfers they almost immediately "warped". As I said above I don't think these things do actually warp, but whatever, they juddered.
They've fixed themselves now though, so I don't think there is an inherent problem, and hence I'll give them a positive review.
Significant saving in un-sprung weight, stop the bike at least as well as stock, look good. Buy, if you have the cash handy.
