Yup. Which is why I didn't ;-) I couldn't find any decent electric carbon ones is all. I may see about getting oem ones dipped. There are a set of Japanese brakes that are good that go under the 15s, but cos I'm blessed with a couple of amazing mates, I can get better for the same or less. But they won't give enough clearance under the 15s to be safe with expansion. Hence my original post.
