Just tried to replace the rt99 rotors on my red etap 22 calipers with XT 800 ones, and I can't stop them rubbing. It's only very light but enough you can hear it. I suspect it's just that they're too thick, so my question is this - apart from the spenny SRAM ones, are there any good centerlock rotor options which are thinner than the Shimano ones (like the SRAM ones are)?

Rotors should be about the same width I think. You need to open pistons fully and center it very carefully, not a lot of clearance with these brakes when all is new

It's fine with a worn (1.6mm) Shimano rotor, just not a new one. They do all appear to be about 1.8 new though. Will swap the pads and see if that helps. Wonder if the spring isn't pushing the pistons back enough/opening the pads enough. It's a very, very slight rub so must just be catching.
